Cast Steel Check Valve

Home/Tags/Material/Cast Steel Check Valve

A cast steel check valve is a mechanical device used in fluid systems to control the flow of fluids by allowing them to flow in one direction while preventing reverse flow. It consists of a cast steel body with a hinged or swing-type disc that opens under forward flow pressure and closes to prevent backflow, ensuring the unidirectional flow of fluids.
