Socket end resilient seated gate valve is one type of gate valve with flexible wedge as its on-off disc, which moving direction is perpendicular with flow. Gate valve can be only full open or full close. They are widely used in series of industries, especially in water supply projects, public works, water treatment plant, fire fighting, etc. Prosper Flow can manufacture resilient seated gate valve according to the standard of ISO 2531 with sizes of 3″~12″ (DN80~300mm).
