Cast iron check valve is a valve that prevents the reverse flow of fluid in pipeline. It is basically composed of valve body, cover, disc and other components. When the fluid flows in the normal direction, the valve disc opens to allow the fluid to pass through; When the fluid flow reversely, the disc closes. It is often used in water supply and drainage systems, industrial pipelines and petrochemical industries.
Cast iron check valves are suitable for a variety of fluid media, including water, oil, gas, etc. It can be installed vertically or horizontally.
Its key benefits are as following:
1.Compact structure: cast iron check valve structure is relatively simple, composed of fewer components, easy installation and maintenance.
2.Corrosion resistance: Cast iron check valves are usually made of corrosion-resistant cast iron materials and can be used in a variety of media for a long time without damage.
3.Good sealing: Cast iron check valve has good sealing performance, can effectively prevent fluid leakage and reverse flow.
4.Wear resistance: the disc of the cast iron check valve is usually treated with surface hardening, so that it has a high wear resistance and extends the service life.
