For the specific applications in different industrial area, we have designed effective series of dual disc check valves. A device two seats that combines in sequence.
It is used to prevent back flow in the system. It performs well with assurance of tight shut off. It is space saving valves. It offers comfortable mounting options. It can be mounted vertical or horizontal.
Depending upon the operational fields, we provide different options for construction materials. We offer cast stainless steel, high alloy steels like alloy-20, hastelloy, cast carbon steel, CD4MCu, cast iron, S.G.iron and as per requirement
Our series of dual disc check valves are manufacturer as per API 594. It is tested confirming API-598. Such series is available with soft sealing and metal to metal sealing. It is also available with rubber seat and PTFE seat.
