Resilient Seated Gate Valve PN25 Product Information
Resilient seated gate valve PN25 is one type of non-rising stem gate valve according to standard of EN1171 and EN1074-2, whose flexible wedge gate is coated with rubber NBR or EPDM. Its moving direction is perpendicular with flow. PN25 gate valve can be only full open or full close. PN25 resilient seated gate valves are widely used in series of industries, especially in water supply projects, public works, water treatment plan, fire fighting, etc. Flowspec Luokai can manufacture and supply the resilient seated gate valve PN25bar with sizes of 2”~12” (DN50~DN300mm).
