Silent Check Valve (TH017)

Product overview:

Silent Check Valve refers to the valve that automatically opens and closes depending on the flow of medium itself, which is used to prevent the backflow of medium, also known as check valve, one-way valve and backflow valve. The valve is suitable for water supply and drainage system, high-rise building pipe network, widely used in the pipeline at the pump outlet. When the medium flows in the specified direction, the valve is jacked open under the action of medium force to realize opening; when the medium flows in reverse, the valve disc and the sealing surface of the valve seat are closed tightly because of the spring force at the back of the valve disc and the reverse force of the medium, and the sealing surface of the valve seat is closed because of rubber sealing, so as to achieve silencing and The purpose of preventing the reverse flow of media.
