The Shaft stem Extension Resilient Seat Gate Valve is usually used for underground service and buried service. The resilient 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 soft seat gate 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.
