Metal Check Valve – Automatic Opening and Closing Valve

The metal check valve is a one-way valve that relies on the medium's own flow and pressure to automatically open and close, specifically designed to prevent backflow of the medium and ensure the safe operation of pipelines and equipment. When the medium flows in the forward direction, the pressure acting on the valve disc or ball causes the valve to open; When the medium stops flowing or flows in the reverse direction, the valve disc or ball returns to its original position due to gravity or spring force, quickly closing the valve.

Primarily made of metal, the valve features a simple structure, high temperature and pressure resistance, and excellent corrosion resistance. It is widely used in the fields of petrochemicals, electric power, metallurgy, and water supply, making it an ideal choice for unidirectional fluid control under high temperature, high pressure, and corrosive conditions.
