The conventional check valve switches off quickly that prompts water surge to cause the piping system pressure rising abruptly and triggers big noise. As a result, the pipeline and other equipments will be severely damaged. The piston slow closed check valve has resolved the problems that the normal check valve brought. The speed of opening and closing can be modulated to decrease the impact of water hammer and minimize noise, therefore making the effect of slow close and silencing noise possible.

Function: the piston slowly closed check valve is not just preventing the fluid reversing, but also it can prevent water hammer or surge occurring. Therefore it makes a safety and silent on/off effect and provides the pipeline with safe operation.
