H81X-16Q Grooved Type Silencer Check Valve

H81X-16Q Grooved Type Silencer Check Valve

PRODUCT DESCRIPTION

1.The grooved silencer check valve is a special valve that combines the groove connection method, silencer function and check function.
2.It is mainly used in pipeline systems to prevent medium back flow.
3.Reduce water hammer impact and reduce noise when the valve is closed.

FEATURES

1.Groove connection：The clamp-type groove connection is adopted, and no welding or thread processing is required during installation. It is fastened by rubber sealing rings and clamps, which simplifies construction and facilitates maintenance.
2..Silence design：Slow closing structure: When the valve disc is closed, it is slowly closed through springs, hydraulic damping or lever mechanisms to avoid the impact noise caused by the instantaneous closing of traditional check valves.
3.Flow channel optimization: The streamlined design inside the valve body reduces turbulence and vibration noise.
4.Check function：The valve disc is opened by the forward flow pressure of the medium, and automatically closed when the medium is reversed to prevent back flow
5.Low noise: The slow-closing design significantly reduces the "water hammer effect" and the impact sound of the valve closing, and is suitable for noise-sensitive environments (such as hospitals and residential areas).
6.Easy installation: The groove connection saves man-hours and is particularly suitable for renovation projects or places with limited space.
7.Durability: The valve disc is mostly made of stainless steel or copper alloy, and the sealing material is nitrile rubber or EPDM, which is corrosion-resistant and has a long service life.
8.Simple maintenance: The detachable structure is convenient for cleaning pipeline impurities or replacing seals

APPLICATION

1.Building water supply and drainage: high-rise building water pump outlet, to prevent water hammer from damaging the pipe when the pump is stopped.
2.HVAC: chilled water circulation system, to reduce the noise of pump start and stop.
3.Fire protection system: protect fire pumps in the sprinkler network to avoid back flow and contamination of water sources.
4.Industrial circulating water: cooling water return pipeline, to reduce the impact of water hammer on the heat exchanger.
5.Municipal water supply: booster pump station outlet, to ensure stable operation of the network.
