Resilient-Seated Gate Valve

Product Code: MD-VLV-0010

Features: Smooth flow surfaces coated with electrostatic powder coating and an EPDM-encapsulated wedge provide 100% tight shut-off. | The body and bonnet are manufactured from ductile iron and withstand the high stresses that may occur in pipelines. | Plastic sliding guides on the wedge ensure low operating torque. | The body sealing system is maintenance-free and corrosion-resistant. The long F5 face-to-face dimension is used. | For DN 250 and larger sizes, a gearbox can be supplied on request. | The wedge and body guide rails provide stable operation. | The stainless-steel operating stem has rolled threads for high strength and low operating torque. | Internal and external surfaces are coated with a minimum 250 µm fusion-bonded epoxy; a 300 µm coating can be applied on request. | Suitable for underground and above-ground service and can be operated by actuator, gearbox, handwheel or extension spindle. | The stem bearing and upper stem nuts are made of MS58 brass; precision machining provides low operating torque. | The streamlined body and wedge design minimizes flow disturbance and pressure loss. | WRAS approved for potable-water service. Applications: Underground and above-ground pipelines | Water treatment plants | Pumping stations | Seawater applications | Fire-hydrant connections | Power plants (cooling-water pipelines) | Potable-water distribution lines
