ORBINOX CANADA, ORBINOX USA, ORBINOX BRAZIL, ORBINOX SPAIN, ORBINOX UK, ORBINOX FRANCE, ORBINOX GERMANY, ORBINOX INDIA, ORBINOX CHINA, ORBINOX S.E.A. www.orbinox.com OBX 11/12 Revision 1 MU-1 The Orbinox model MU is a 4 sided sealing penstock. The gates are suitable for different types of applications with a highly versatile flow control for waste water treatment plants, irrigation, hydraulic works and hydro-electric power plants. From sizes 150 mm x 150 mm to 1200 mm x 1200 mm, the MU model has a unique seal design that can achieve minimal equal seating and unseating (bidirectional) leakage rates. Sizes 1300 mm x 1300 mm up to 2000 mm x 2000 mm are available in both uni-directional (only suitable for seating water heads) and bi-directional configurations. The maximum leakage rate is lower the maximum allowable recommended by DIN 19569-4 (class 5) and AWWA C561 under normal conditions. Orbinox also designs and manufactures the MU model penstock in larger sizes, for more demanding service conditions. For more information please contact an Orbinox representative. The MU penstock is manufactured in general accordance to DIN 19569. Other standards such as AWWA C561 and BS 7775 also available. The standard MU model is manufactured in stainless steel which has a higher corrosion resistance in many applications which results into a longer life cycle with little or no maintenance. Other materials of construction are available upon request, such as AISI 904L, Duplex stainless, etc. GENERAL DESCRIPTION CONSTRUCTION DESIGN MODEL

In order to be able to operate the gate, stem extensions are necessary. Stem guides are used to limit the “unsupported” length of the stem extension in order to avoid any buckling failure. The stem guide has a HWMPE guide to reduce friction between the guide and the extension. Non-Rising Stem Configuration As standard, non-rising stem gate configurations are used with self-contained frame designs. Therefore, the stem extension does not support the axial load (only torque) and less wall brackets are required. As a general rule, a stem guide should be installed every 3 meters of unsupported stem extension. Rising Stem Configuration As standard, rising stem gate configurations are used with open-frame designs. Therefore, the stem extension has to support the axial load when the gate is operated. In consequence, the use of stem guides are critical to avoid any buckling failure. As a general rule, a stem guide should be installed every 2 meters of unsupported stem extension. This section briefly describes the installation, operation and maintenance of MU penstocks. For more detailed information please refer to the “MU IOM Manual”. Installation: Orbinox MU penstocks are installed by means of Anchor Bolts. Depending on the size and working conditions they shall be either of the mechanical or chemical type (see table below). In order to avoid leakage between the concrete wall and the frame, Orbinox recommends the use of construction sealant equivalent to Sikaflex 11FC sealant (200ml per meter of opening perimeter). The minimum concrete strength shall be 20.7 MPa. The tolerance of the concrete construction (flatness, levelness and plumbness) shall be in accordance to DIN 18202. For detailed information about type, size and quantity of the required anchor bolts at the installation, please refer to the notes on the “General Arrangement Drawing”. Maintenance and Operation: The Orbinox MU penstocks need practically no maintenance. The stem shall be kept lubricated and seals shall be replaced if damaged. The MU penstock is closed by applying a clockwise rotation. Applying too much force on the operator when closing the gate may cause damage to the stem.
