In-line NRVs: This type of non-return valve uses a spring and the flow is allowed when the upstream pressure exceeds the spring tension. Again when the pressure goes below the pressure to overcome spring tension the flow is blocked. Folding Disc NRVs: Mainly used for gaseous or low-pressure liquid service, this type of non-return valves are made in a wafer body pattern.

Disc Check Valve prevent the overturn flow of release fluid in the closed method, hence recommended for guaranteed non return valve flow for any liquid & gas process. They are also proper for wide range of fluid purpose such as hot water, process lines, and condensate and water arrangement. Our accessible valve with disc and spring construction
