Class150 Class300 Ductile Iron Wafer Check Valve

Short Description:

Ductile iron Dual Plate Wafer Check Valves, wafer check valve

The dual-plate check valve opening and closing member is opened or closed by the medium flow and the force to prevent the back flow of the valve from being called a check valve. Check valves are automatic valves, mainly used on pipes with one-way flow of media, allowing only the media to flow in one direction to prevent accidents.

The dual-plate check valve is used for pure pipelines and industrial, environmental, water treatment, high-rise building water supply and drainage pipelines to prevent reverse flow of media. The check valve adopts a clip type, the butterfly plate has two semicircles, and the spring is forcibly reset, and the sealing surface can be a body wear welding wear material or a lining rubber, and the utility model has wide application range and reliable sealing.
