The valves are supplied with the obturator in closed position, to prevent damage to the stem during transport and storage. Flanges or weld ends are closed with protective covers. A one-coat alkyd/acryl enamel, blue RAL 5002, is applied at the factory to protect the external surfaces.The flangefaces havebeen coated with an anti-corrosive which can easily be removed. The inner surfaces are protected with full ...

To prevent corrosion damage to the external surfaces of the valve when installed in corrosive environments, it must be coated with a coating which is suitable for the conditions specific to the plant. Moving parts (e.g. stems) must not be coated, so as not to impair the reliable function of the valve. 6 Commissioning and operation STAAL gate valves are intended for use in gate positions “closed” or ...

pressure has been released. Be aware that even with the pipeline in a pressureless state, the valve body may still be under pressure when the valve is in closed position. For this reason, the valve must be in the semi-open position when the pressure is released from the pipeline. During routine inspections, the loss o ...

Maintenance and repair work to gearbox and/or actuator If a valve with handwheel which has not been prepared by the factory for fitting a gearbox and/or actuator is to be converted, it will be necessary to weld on a mounting flange. The threaded bush may have to be changed, too, depending on the model. 8.1 Correct fitting of mounting flange, correct installation of threa ...
