Non-slam check valves, also known as silent check valves, have a short-stroke piston and a spring that opposes the piston’s linear motion in the flow direction. The non-slam check valve’s short stroke and spring action allow it to open and close rapidly, reducing the shockwave impact of the water hammer and getting the name silent check valve.
Application:
The main purpose is to be used in pipeline systems that require controlling the direction of fluid flow and reducing noise. Its application areas include but are not limited to: pipeline systems in water supply systems, drainage systems, chemical industry, pharmaceutical industry, food industry, and other fields.
Noise reduction function: It can effectively reduce the impact and noise generated by the fluid when the valve is closed, and reduce the vibration and noise of the pipeline system.
Check function: It can prevent the backflow or reverse flow of fluid, ensuring the normal operation and safe operation of the pipeline system.
