BIG SIZE RESILENT SEATED GATE VALVE

Big Size Resilient Seated Gate Valve Product Information

Big size resilient seated gate valve is large sized resilient seated gate valve from 14″ to 40″ (DN350~DN1000mm). Its on-off disc is the flexible wedge gate, whose moving direction is perpendicular with flow. Resilient seated gate valve can be only full open or full close. Water gate valves are widely used in series of industries, especially in water supply projects, public works, water treatment plan, fire fighting, etc. We can design and manufacture the big sized gate valve according to standard of EN1171 and EN1074-2 with sizes of 14”~40” (DN350~DN1000mm).
