Engineering Steam Solutions





“Floline” Offers Disc check valves (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.



•  Disc Check Valve is an advanced design which gives full flow and occupy very less space than other type of Non Return Valve. • •  DCVs are simple to fit between two pipe flanges.
•  Spring loaded disc to prevent reverse flow in pipe lines.
•  Stronger, lighter and smaller than conventional swing check valves, hence less expensive to install and maintain.
•  Compact Design of valves fexibly accommodates various types of flange selection.
•  The valves can be fitted in any plane/direction in pipelines.
•  Available in 15mm to 200 mm sizes.
•  Extremely low operating pressure. Self centering type design.
•  Zero leakage for soft seated valves.
•  Design : Manufactures standard
•  Testing : As per API 598

Oprations :

Disc Check Valves are opened by the pressure of the fluid and closed through compression spring
as soon as flow stops thus preventing reverse flow.

Oprations :

Designed and Manufactured in accordance with BS 7438
