Silent operating valves for air and gas pipeline systems
Position: valves series
Summary
The Silent operating valves for air and gas pipeline systems uses the outline design conformed to hydraulics so as to get a better faired water path and there is an elevator design used inside it for the guarantee of minimum pressure loss. It is mounted on the outlet of the water pump and can close quickly before the water flow goes back so as to avoid the water hammer, water shock sound and destructive shock and to get the target of silencing, back-flow preventing and equipment protecting. It is used extensively for the systems of the water supply and drainage, fire-fighting, warming industries etc.
