Care of Materials
08/2018
95-03091
Page 7
Care of Component Materials
NOTE: SPX FLOW recommends the use of an FDA-approved anti-seize compound on all threaded
connections.
WARNING
Failure to comply with the Care of Component Materials could lead to bodily injury.
Stainless Steel Corrosion
Corrosion resistance is greatest when a layer of oxide film is
formed on the surface of stainless steel. If film is disturbed or
destroyed, stainless steel becomes much less resistant to
corrosion and may rust, pit or crack.
Corrosion pitting, rusting and stress cracks may occur due to
chemical attack. Use only cleaning chemicals specified by a
reputable chemical manufacturer for use with stainless steel. Do
not use excessive concentrations, temperatures or exposure
times. Avoid contact with highly corrosive acids such as
hydrofluoric, hydrochloric or sulfuric. Also avoid prolonged
contact
with
chloride-containing
chemicals,
especially
in
presence of acid. If chlorine-based sanitizers are used, such as
sodium hypochlorite (bleach), do not exceed concentrations of
150 ppm available chlorine, do not exceed contact time of 20
minutes, and do not exceed temperatures of 104°F (40°C).
Corrosion discoloration, deposits or pitting may occur under
product deposits or under gaskets. Keep surfaces clean,
including those under gaskets or in grooves or tight corners.
Clean immediately after use. Do not allow equipment to set idle,
exposed to air with accumulated foreign material on the surface.
Corrosion pitting may occur when stray electrical currents come
in contact with moist stainless steel. Ensure all electrical devices
connected to the equipment are correctly grounded.
Elastomer Seal
Replacement Following
Passivation
Passivation chemicals can damage product contact areas of this
equipment. Elastomers (rubber components) are most likely to be
affected. Always inspect all elastomer seals after passivation is
completed. Replace any seals showing signs of chemical attack.
Indications may include swelling, cracks, loss of elasticity or any
other noticeable changes when compared with new components.

Installation
When installing the valve, ensure that no foreign materials (e.g.
tools, screws, welding wire, lubricants, cloths, etc.) are enclosed
in the system.
Location
The valve must be in a vertical position to ensure that the vent/
drain outlet system functions properly.
The vent/drain outlet at the bottom of the Mix Proof valve must
not be obstructed. The unrestricted vent/drain outlet must allow
leakages and cleaning/rinsing/sterilization fluids to go to
atmosphere in order to guarantee mix proof safe separation. If
hoses, pipes, or other components are mounted to the vent/drain
outlet to prevent splashing of leakage and cleaning/rinsing/
sterilization fluids, then they must be designed such that the fluids
flow freely to atmosphere.
Locate the valve for easy access for inspection.
Ensure that the valves and pipe systems drain properly. The two-
piece body option enables the positions of the connections to be
adjusted in relation to each other.
Welding Instructions
Figure 1 - Valve orientation
VA100-725
Prior to installing, thoroughly inspect each valve. When using
buttweld two-piece body valves, clamp connections must be used
on either the upper or lower body to allow for servicing of the o-
ring seal between the bodies. This does not apply to single-piece
bodies.
Mix Proof valves with welded connections require the following to
be performed before installation:
•
Prior to installation, remove the stem actuator assembly and
lower bearing carrier.
•
Remove all seals from the body.
•
Weld the body into position, ensuring that the connection is
free of tension and distortion.
NOTE: Orient the valve so that the "UP" inscription (near the
adapter-to-body connection) is pointed toward the actuator. See
Figure 1.
CAUTION
Welding must be carried out by qualified personnel.
For manifold welding, fixture tables are recommended. Matrix
manifold welding requires a controlled deliberate process to
maintain the alignment of the parts.
Air Supply
Install the valves using dry, filtered air. Lubrication is not required.
If using lubricated air, refer to the solenoid manufacturer’s
specifications. The air supply must be 75 to 90 psi (5.2 to 6.2
bar).
Flow Direction
The valves should be installed to close against the flow to prevent
water hammer.
CAUTION
CAUTION
Isolate products away from the valve
prior to performing maintenance.
CAUTION
Before attempting to buttweld an
automatic valve into a line, disassemble
the body from the actuator. Dissipate
heat away from the valve body to
prevent warping.

Fittings
When using suitable fittings, Mix Proof valves with detachable
connections can be installed in a pipe system per the fitting
requirements. The valve must be installed free of tension. After
the valve is installed in the pipe system, attach the control air
hoses and connect the electrical supply.
Pipeline Support
Install adequate supports to prevent strain on the fittings, valves
and equipment connections.
.
1.
Install supports at least every 10 feet on straight runs of
piping. (Figure 2, item C).
2.
Install supports on both sides of the valves as close as
possible to the connections. (Figure 2, item D).
3.
Install supports at each change of pipeline direction. (Figure
2, item E and F).
4.
For pipelines passing through walls, floors or ceilings, provide
at least 1 inch (25 mm) of clearance around the pipe to allow
for expansion and contraction. (Figure 2, item G).
CAUTION
In higher temperature applications, ensure proper accommoda-
tion for thermal expansion in the pipeline design to minimize
stresses on the valve bodies. Excessive mechanical and thermal
stresses can distort and damage the valve bodies.
Installing Valve Manifolds
Install automatic valve manifolds with a uniform pitch for proper
drainage. Elevate one corner of the cluster and pitch 1/16" per
foot (1.59 mm per meter) if desired. Arrange the supports for the
floor-mounted valve manifolds to provide alignment of the inlet
and outlet lines.

Connect the electrical control cord to the valve at location A
(see Figure 4).
NOTE: Control tops are available with strain relief cord grip for
hard wiring or threaded pin connectors for quick disconnect.
Mating cables must be ordered separately.
7.
Operate the valve through the available conditions (closed,
open, upper seat cleaning and lower seat cleaning). See
Table 3, “Solenoid/Valve Position,” on page 17.
Quality of Control Air to
Control Module
Do not exceed the following values:
•
Suspended solids content:
Particle size: 5 microns max.
Particle Density: 5 mg/m3 max. (= quality class 3)
•
Water content: Dewpoint +35°F (+1.6°C)
(= quality class 3). For applications at great elevations or at
low ambient temperatures, the dewpoint changes.
•

(= quality class 5).
External Flush - Liquid
Vent Cavity
NOTE: Liquid flush of the vent cavity is
typically used in applications with high
sugar content product that may
crystallize if dried. Cavity flush is
recommended after valve transitions to
keep the seats and cavity moist.

Connect the cavity cleaning supply to a suitable liquid supply to
flush the vent/drain (Figure 7) during the operation of the
processing system.
The flush supply line can be connected to the pipe system by 1/4"
(6 mm) rigid or poly flow tubing. The flush supply is blocked when
the valve is open.
Connect the supply line to the adapter connection with poly flow
tubing (Figure 7).
WARNING
During CIP cleaning and valve opening (W71), fluid escapes from
the drain port. Drain this off to prevent a possible hazard to per-
sonnel.
Regulate the flush supply (Figure 7, item A) for pressures of 30
psi minimum, 50 psi maximum.
The maximum solution temperature is 180°F (60°C).
WARNING
Cavity cleaning operation must fall within the fail-safe control sys-
tem. See “Cleaning” on page 23.
WARNING
Take proper precaution to safeguard the flush water supply, such
as installing backflow prevention devices.

Steam Vent Cavity, Upper and Lower Stem
Use both Upper Stem Steam Flush Adapter and Lower Stem
Steam Adapter.
This option allows continuous steaming of the vent cavity (in both
open and closed positions), upper and lower stems.
DANGER
Valves equipped with the steam flush option for stem and vent
cavity can produce high temperatures and steam hazards that
may result in personal injury or death.
To steam flush the upper and/or lower stem as well as the vent
cavity, the Mix Proof Valve must be ordered with the Steam Flush
for stem and vent cavity. This option (See Figure 9 on page 12)
contains the following components:
•
External flush connection, 1/4" NPT.
•
Modified adapter with removed o-rings to flush the stem.
•
Jacket with 1/4" Tube (S.S.) on lower balancer to flush the
lower stem (balancer).
•

Installation
Installation of a steam flush system on a W70 Series Mix Proof
valve should be done only by a licensed Steam Fitter.
The valve must be installed vertically to drain out any steam/
condensate and have a drain funnel placed directly below it.
Refer to Figure 9 to see the shut-off valves in the supply lines.
Function
The low pressure steam enters through port B of the upper stem
steam flush adapter. Steam purges the outside and inside of the
upper stem and the vent cavity. Steam exits out the leakage port
F.
For steam flushing the outside of the lower stem (balancer), the
low pressure steam enters port D and exits at port E.

Operating Parameters
Temperature Range:
No special precautions are required for applications within a tem-
perature range of 32°F to 180°F (0°C to 82°C).
For applications above 190°F (88°C), clearances can be affected
by excessive thermal expansion when the valve is installed in
compact fabrications or manifolds. Valve bodies have thicker
cross-sections than tubing, but thermal expansion can affect
clearances in interconnecting piping sections.
Operating valves above 180°F (82°C) could result in shortened
life of elastomers and/or erratic valve operation.
If operating below 32°F (0°C):
•
Control air must have an appropriately low dew point.
•
Valve stems must be protected from icing to ensure long
working life for valve stem seals.
Solenoid valves may not be used in the control module in room
environments below 32°F (0°C) and over 140°F (60°C), as func-
tion cannot be guaranteed.

Operation
All functions of W70 Series Mix Proof valves are pneumatically
controlled using a 75 min. to 90 max. psi (5.2 to 6.2 bar) clean air
supply.
The valve contains a large and small spring in the valve actuator.
The springs compress the valve seats to seal closed.
Large Spring
•
Located in top air chamber of cylinder.
•
Holds valve in the closed position.
Small Spring
•
Located in the extended hub of the upper piston.
•
When the valve is open, the spring acts on the upper seat
stem to hold the upper and lower plugs together.

Test Procedures
Positive Fail-Safe Detection Test
Perform a test to verify the fully closed fail-safe position. The
valve stem feedback proximity sensors should be set for the fully
opened and fully closed positions of the valve. See Figure 12 for
port and corresponding chambers.
Decommission the system, drain the lines and lock out the
pumps.
1.
With the valve fully closed, confirm that the proximity sensors
conform to the tables on page 18. Verify the sensor status on
the PLC control system.
2.
Pressurize air chamber 1 to open the valve. Confirm that the
proximity sensors conform to the tables on page 18. Verify
the sensor status on the PLC control system.
3.
Vent air chamber 1 to close the valve.
4.
If used, activate the upper seat lift either through the control
system or by supplying air to port 2.
5.
When the upper seat lifts, confirm that the proximity sensors
conform to the values in the tables on page 18. If the yoke
area does not have a limit sensor, visually confirm the upper
seat lifting.
6.
Vent the air in chamber 2 to deactivate the seat lift.
7.
If used, pressurize air chamber 3 to activate the lower seat
push.
8.
Confirm that the proximity sensors conform to the tables on
page 18. Verify the sensor status on the PLC control system.
9.
Vent the air in chamber 3 to deactivate the seat lift.
10. Disconnect the air from the valve actuator, placing the valve
in the fail-safe position. Verify that the proximity sensors reg-
ister that the valve is fully closed.
Corrective Action
If the double seat Mix Proof valve fails to respond as indicated
above, immediately check the valve assembly and wiring to
locate and correct the cause:
•
First, check the proximity sensor adjustment.
•
Check for the correct assembly and adjustment of the valve.

Maintenance
Maintenance Intervals
Maintain adequate stock of replacement parts. See the items in
bold beginning on page 38 for recommended spare parts.
Maintenance intervals should be determined by the user and
specific application, based on the following conditions:
•
Daily operation period
•
Sensoring frequency
•
Application parameters, such as temperature, pressure, and
flow
•
Product type
•
CIP time and temperature
Use the following recommendation as a rough guide:
•
For fluid temperatures ranging from 180°F to 212°F (82°C to
100°C): approx. every 3 to 6 months
•
For fluid temperatures of 140°F (60°C) and lower: approx.
every 12 months
The values listed above are only general guidelines and do not
apply, for example, to fluids which crystallize on contact with air.
The values listed are subject to the chemical resistance of the
seal material.
W70 Series Mix Proof valves operate best at temperatures below
180°F (82°C), regardless of seal type.
The maximum temperature of 280°F (138°C) listed for the seat
seal type is the rating for the elastomers only, in a static
condition. This is not the temperature rating for the valve in
operation.
The 180°F (82°C) max. rating also applies to valves welded
together in a manifold. Operating W70 Series Mix Proof valves at
temperatures above 180°F (82°C) could result in shortened life of
elastomers and/or erratic valve operation.

Inspection
Inspect the following on a regular basis:
•
Actuator connections for air leaks
•
Valve body and stem O-rings
•
Valve seats (If leakage occurs, see “Troubleshooting” on
page 61.)
•
Pneumatic connections:
–
Air pressure at supply connection
–
Air lines for kinks and leaks
–
Threaded connections for tight fit
–
Clean air filter at regular intervals
•
Electrical connections secure on control module:
–
Wire connections tight on terminal strip
–
Electrical connections to control module
–
Threaded strain relief for tight fit.
Lubrication
No lubrication is required other than as noted in the disassembly
and assembly procedures. Use Dow Corning #7 or equivalent
food grade non-petroleum (silicone) grease on seals and O-rings.
Apply Bostik Never-Seez® White Food Grade with PTFE or
equivalent to all bolts and threaded stem parts.
Cleaning
Cleaning-In-Place (CIP)
CIP methods can be used to clean installed automatic valves
without disassembly. Select methods based on the specific
requirements of sanitarians and each application. Check with
local chemical suppliers for the most effective cleaning agents
and procedures intended for the application, in order to properly
dissolve the product residue. Ensure that the cleaning agent is
compliant with the temperature range and elastomer material.
Mix Proof valves can be fitted with a 1/4 NPT flush connection for
rinsing the area between the seats and the vent/drain port. The
area can be flushed regularly in the event of long times between
CIP cleanings. See “External Flush - Liquid Vent Cavity” on
page 10.
DANGER
Do not put a hand into the yoke or body
of a pneumatically-actuated valve.
VA100-359b
CAUTION
Avoid splashing any liquid into the air
vent of the actuator during clean up
NOTE: Actuate each valve or use seat
lifting to ensure effective cleaning and
sanitizing. Expose all product-contact
surfaces to the appropriate cleaning
solutions.

Cleaning Procedure
Mix Proof valves are designed to use a cleaning solution supplied
by a CIP system. The vent outlet/cavity must be unobstructed to
guarantee the leakage of fluid to atmosphere.
Establish cleaning procedures for each installation depending on
product characteristics, operating parameters (temperature,
velocity, valve cycles), and product velocities.
The following statements are intended as suggestions or
guidelines for cleaning procedures and will vary by application:
•
For seat lifting valves, when the upper or lower body is in
CIP, seat movement should occur. Seat cleaning positions
are factory-set and marked in the yoke area. Seat cleaning
will produce visible leakage from the vent outlet. Brief
multiple lifts should occur for each step in the CIP program,
excluding the initial rinse.
NOTE: Seat cleaning is not
recommended during the initial rinse.
•
Maximum Solution Temperature is 180°F (82°C).
•
Maximum line pressure during seat cleaning is 90 psi (6.2
bar).
•
Minimum cleaning solution velocity is 5 ft/s (0.3 m/s).
•
Cleaning time is dependent on the inlet pressure. The
recommended cycle time is 3 to 5 seconds per cycle after the
valve achieves the seat clean position. This seat clean cycle
time of each valve should be visually confirmed during
commissioning.
•
Typical cleaning procedures include pulsing the seat during
cleaning until the valve has been demonstrated to be clean.
This is usually accomplished in 3 to 5 consecutive pulses per
step in the CIP program; however, each installation and
product varies, so pulsing should continue until all product/
debris is removed.
•
For the optional external flush of the vent cavity, water flush
can be activated during the final rinse.
•
Every few months of operation, remove and inspect one
valve in the system to ensure that complete cleaning is being
achieved.
CAUTION
During valve opening and CIP cleaning,
fluid escapes from the drain port. Drain it
off to prevent any possible hazard to
personnel.

Seat lifting models are factory set. See Figure 18 and Figure 19.
Scribe lines (item A) within the acid-etched adjustment zone (item
B) provide a visual indication of the correct factory-set
adjustment. Screw the adjusting sleeve and adjusting nut until the
bottom edges align with the scribe line as shown in Figure 19,
item A.
NOTE: Always adjust the lower seat clean first.
WARNING
Do not adjust the seat clean collars with pliers, vice-grips or
adjustable jaw pliers (channel locks).
If required, adjust the seat movement. With the valve closed,
using a 3/16" diameter pin spanner or allen wrench, adjust the
movement of the seats to the factory settings or within the
adjustment zone (Figure 18 and Figure 19, item B). Once a
successful seat movement is established, clearly mark where the
bottom edges of the adjusting sleeve and adjusting nut align, to
ensure proper resetting after disassembly.
Lower seat
Operate the lower seat clean cycle multiple times. Observe the
indicator stem movement at the top of the actuator, or at the
balancer on the bottom of the valve.
To adjust the movement of the lower seat for cleaning, rotate the
adjusting sleeve in the yoke (Figure 20, item B):
•
W71: Rotate right to increase; left to decrease.
•
W72RS: Rotate left to increase; right to decrease. See also
“W72RS Lower Stem Measurement” on page 26.
Upper seat
Operate the upper lift cycle multiple times. Observe the outer
stem movement by watching the adjusting nut in the yoke (Figure
20, item A).
•
To adjust the movement of the upper seat, rotate the
adjusting nut (Figure 20, item A) left to increase; right to
decrease.

W72RS Lower Stem Measurement
For the W72RS models, the location of the lower stem is more
critical than the stem travel. Confirm the proper location of the
lower stem by measuring the distance from the lower seal
retainer to the lower shoulder of the stem (Figure 21, dimension
"A") when the valve is static.
•
To increase this measurement distance and allow more
cleaning of the lower seat, turn the adjustment sleeve to the
left.
•
To decrease the distance and allow less cleaning of the lower
seat, turn the adjustment sleeve to the right.
Removing Valve from
System
Before removing the actuator/valve stem assembly from the valve
body, drain all product lines connected to the body.

Actuator O-ring and
Bearing Replacement
CAUTION
The valve stems and actuator must be removed from the valve
body before servicing the actuator components.
CAUTION
Although WCB fully-maintainable actuators are designed with a
contained spring for safety, always use caution when handling
any piston/spring assembly as any compressed coil spring can
be extremely dangerous.
NOTE: Do not pressurize the actuator with air when the stems
are removed. This may tear the O-rings and cause the actuator to
leak air when it is re-assembled.
NOTE: If present, the control module must be removed to replace
the O-rings and bearings in the top of the cylinder assembly.
Please refer to control module publication 95-03083.
