Wafer Type Check Valve, Forged Valves Manufacturer In India

We offers disc check valve (wafer type) especially for chemical, Food processing, Pharmaceuticals, Pulp and Paper, Textiles, Power generation, Refrigeration & Air Conditioning etc. The valves are used in Oil lines, Processing line, Hot and cold water systems, steam and condensates, Gas lines etc.

Size Range : 1/2″ to 4″ Screwed
Size Range : 1/2″ to 12″ Wafer Type
Operation : Disc Check Valves are opened by the pressure of the fluid and closed through compression spring a soon as flow stops thus preventing reverse flow.
Standard : Designed and Manufactured in accordance with BS 7438
Application : Air, Water, Light Oil, Gas, Light Chemical
Size Range : 1/4″ to 6″ Screwed / Flanged / Triclover End

Silent Features

Self centering type design.
Testing : As per API 598.
Available in 15 mm to 300 mm sizes
Extremely low operating pressure.
Zero leakage for soft seated valves
DCVs are simple to fit between tow pipe flanges.
Spring loaded disc to prevent reverse flow in pipe lines.
The valves can be fitted in any plane / direction in pipe lines.
Disc Check Valve is an advance design which gives full flow and occupies very less space than other type of Non Return Valve. This also available IBR Certificate in Form III C.
Compact Design of Valves flexibly accommodates various types of flange selection’s Stronger, lighter and smaller than conventional swing check valves, hence less expensive to install and maintain.
