Introduction to Check Valve

secureluokai 四月 24, 2026

A check valve is a self-actuating valve device that opens and closes automatically by the power of the fluid itself. Its core function is to prevent medium backflow and ensure the stable one-way flow of piping systems.

Widely applied in industrial fluid control, hydraulic systems, water supply and drainage engineering and other fields, check valves play a vital role especially in scenarios where reverse impact and contamination need to be avoided.

Its working principle adopts the coordinated design of fluid mechanics and mechanical structures. The pressure difference generated by medium flow drives the movement of the valve disc, achieving reliable sealing without external energy supply.
