OS&Y rising stem resilient seat gate valve

SUZHOU RSF VALVE is one of leading manufacturers of water works valves in China. We have more than 15years experience in producing resilient seat gate valve, metal to metal seat gate valve, non return valve ( swing check valve, ball check valve, dual plate check valve, nozzle check valve, tilting disc slanted butterfly check valve), globe valve, strainer, etc.

The EN1171 DIN3352 ductile iron OS&Y rising stem or non-rising stem resilient seat gate valve simple design makes it one of the most common water works valves in use. It can be applied to both liquid and gas services, although it is mostly used in liquid services. The soft seated gate valve was designed primarily for on-off service, where the resilient seated sluice valve is operated infrequently. It is not recommended to partly open the valve for adjustment of flow rate or emergent pressure relief blow-off. RSF’s resilient seated gate valve is widely used in the industry of potable water, sewage, and sea water.
