CI Wafer Type Check Valve

Cast iron wafer check valve is a kind of automatic valve, which relies on the force generated by the flow of the medium itself to open and close automatically. The main function of this type of valve is to prevent the backflow of the medium in the pipeline. Usually, when the medium flows in the positive direction, the pressure will push the valve to open; and when the medium flows in the opposite direction, the valve will be in the medium pressure and its own gravity under the action of the closure, so as to prevent the reverse flow of the medium!

ci wafer type check valve Description

 

Cast iron wafer check valve is a cast iron valve body as the main material, using the wafer connection structure of the one-way flow control valve, through the valve flap automatically open and close to prevent backflow of fluids, to protect pumps, pipelines and other equipment. Typical applications include low and medium pressure water supply systems, building water supply and drainage and general industrial processes.

Core component design
Valve body material: HT200/HT250 grey cast iron, with medium corrosion resistance and economy, suitable for normal temperature, non-strong corrosive media (such as water, low pressure steam);
Valve flap type: rotary opening type or butterfly valve flap (double/single), using cast iron, bronze or stainless steel, to meet different sealing needs;
Seal form:
Elastic seal: valve seat embedded EPDM or NBR rubber ring, suitable for low pressure clean media;
Metal hard seal: valve and seat surfacing wear-resistant alloy, particle abrasion.
