Noise Control Check Valve

Silencing check valves are mainly used in valve design to avoid absorbing and reducing pressure wave noise during opening and closing. Optimized flow channel design can improve the flow direction of the medium, reduce the flow resistance coefficient, and thus reduce the noise generated by the fluid during the flow process. Valve disc sealing materials usually use rubber soft seals, which have good sealing performance and can provide cushioning when the valve disc is closed, reducing the impact sound of the valve disc on the valve seat; The improvement of the spring reset mechanism also enables the spring to help the valve disc quickly and smoothly close when the medium stops flowing or flows back, reducing and avoiding the noise caused by the valve disc directly hitting the valve seat in traditional check valves. Therefore, the noise reducing check valves produced by Shanghai Meiyan Yi Pump Valve are widely used in environments that require quietness.
