Non Rising Stem Sewer Gate Valve 8 Inch PN16 Nut Type

DIN-F4 Non-rising Stem Resilient Seated Gate Valve Brass Nut Type

1. PRODUCT PROFILE

DIN-F4 Non-rising Stem Resilient Seated Gate Valve Brass Nut Type is one type of gate valve with flexible wedge as its on-off disc, which moving direction is perpendicular with flow. Gate valve is one of the most widely used valves in various fluid transportation projects.In traditional gate valves, there are common phenomena such as fluid leakage and serious internal corrosion. Common soft-seal gate valves and stems on the market The shaft seal is easy to leak, and it is impossible to replace the seal ring under the condition of constant water and any opening. Prosper Flow resilient seat seal gate valve adopts novel structural design, strict manufacturing technology and high-performance new materials, which overcomes the traditional gate seal failure. can manufacture resilient seated gate valve according to the standard of DIN3202 F4/F5/BS5163 with sizes of 2″~12″ (DN50~300mm).
