Flanged Gate Valves
Elastomer Seated Gate Valve
An elastomer seated gate valve is a flanged isolation valve in which a rubber-coated wedge (disc) moves vertically inside the body and is raised and lowered by handwheel to open and close the line. When fully open, the flow path is as free as the pipe diameter, with virtually no pressure loss; the rubber-coated wedge closes against the body bottom without leaving a cavity, ensuring leak-free sealing.
With GGG40.3 ductile iron body and cover, rubber-coated cast wedge and NBR/EPDM sealing, it is used in water from DN40 to DN450 at 16 bar working pressure and up to 80 °C. Short (F4) and long (F5) face-to-face length series are available.
