Resilient-Seated Gate Valve (F4), Ductile Iron

Product Code: MD-VLV-0009

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. | POM sliding guides on the wedge ensure low operating torque. | The body sealing system is maintenance-free and corrosion-resistant. | The short face-to-face dimension (DIN 3202 F4) minimizes installation space. | For DN 350 and larger sizes, a gearbox can be supplied on request. | Suitable for both underground and above-ground installation. | The bonnet bolts are wax-coated to protect them against corrosion. | 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 as an option. | 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. | Each time the valve is opened, the flow cleans the sealing surface and prevents dirt and sediment build-up. | WRAS approved for potable-water service. Applications: Pipelines | Water treatment plants | Pumping stations | Tanks | Seawater applications | Power plants (cooling-water pipelines) | Industrial applications
