Technical parameters and characteristics
Silent Check Valve
This Silent Check Valve is designed by our engineers and technicians with reference to advanced products of the same type at home and abroad. The internal flow passage is streamlined and equipped with a fluid guide, which greatly reduces the fluid resistance. The valve is mainly used at the outlet of the water pump or other places to prevent the backflow of the medium, which can effectively prevent the water hammer impact and noise generated when the medium of the ordinary check valve backflows, thus extending the service life. Multi-element sealing structure is adopted: metal and rubber are combined, and the sealing surface of the valve seat is sealed with a cone, which can be closed tightly under medium and low-pressure conditions without leakage, overcoming the shortcomings of poor sealing performance of general check valves.
