Product Details

working principle:

When the medium flows in the specified direction, the valve disc is pushed open by the force of the medium to achieve opening; when the medium flows back, the sealing surface of the valve disc and the valve seat is tightly sealed due to the spring force on the back of the valve disc and the reverse force of the medium. Fitting and closing, because the valve disc sealing surface is sealed with rubber, it can achieve the purpose of silencing and preventing the backflow of the medium.

Features:

Silent check valve refers to a valve that relies on the flow of the medium itself to automatically open and close the valve disc to prevent the backflow of the medium. It is also called a check valve, one-way valve, and reverse flow valve. This valve is suitable for water supply and drainage systems, high-rise building pipe networks, and is widely used in pipes at the pump outlet.
