Dharmi Engineers Disc Check Valves feature a wafer type, compact and rugged Cast Carbon Steel or Stainless Steel design and are suitable for any process liquid, air, gas, steam etc. The Single Disc Check Valve (Wafer Type Disc Check Valve) consists of four main components: the body, a disc, a star guide and a spring. The Disc check valves are opened by the pressure of fluid and closed through compression spring as soon as flow stops thus preventing reverse flow.
The design of Wafer Design, Sandwich Type Single Disc Spring Loaded Check Valves allows them to be installed between any flanges of different standard and in any position; including vertical pipelines where the fluid flows downwards. Wafer Type Spring Loaded Single Disc Check Valves is also available with Zero Leakage by the use of Soft Seat. Dharmi Engineers has cover Disk Check Valve up to 4” (DN100) Size and Pressure Rating up to 300#.
