Product Overview
A 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, silencer check valve, counterflow valve, and back pressure valve. . Its main function is to prevent the backflow of the medium, prevent the reverse rotation of the pump and drive motor, and release the container medium. It can also be used on pipelines supplying auxiliary systems where the pressure may rise above the system pressure. Mainly used for pure pipelines and industrial, environmental protection, water treatment, high-rise building water supply, and drainage pipelines to prevent the reverse flow of media.
Product Features
The valve disc is guided by the central axis at both ends of the inlet and outlet, opening and closing flexibly, and can be installed horizontally or vertically. The valve disc is spring-loaded, and its rapid closing can effectively reduce water hammer pressure, with good sealing performance and no noise when closing. Wear-resistant and long service life.
