Resilient seated gate valves
T.I.S. resilient seated gate valve is a bidirectional on/off full port valve, made of ductile iron and designed for the supply and distribution of drinking water and also used in sewage water treatment plants.
The wedge is fully rubber lined with high quality EPDM material, which ensures a perfect hydraulic sealing of the valve: thanks to the elastic features of the rubber, the obturator can recover its original shape also after long periods of compression when the valve is closed. During opening and closing operations the sliding friction of the wedge on the valve body is reduced by its slippery guides: in this way the operating torque is lowered, and the valve life is extended.
Resilient seated gate valve is generally equipped with an operating handwheel, but versions with square cap, with stem extension, with position indicator, with manual gearbox or with electric actuator are available upon request.
The valve is suitable for drinking water application: the fusion bonded epoxy process (FBE), with certified resin powders used for internal and external surfaces, guarantees a heavy corrosion protection.
