SINGLE DISC CHECK VALVE

Light weight, versatile design - 80% to 90% less than conventional full-body swing check valves Single Disc opening, Single integrated arm/ disc assembly, Spring-loaded disc calculated to increase the responsiveness of the disc, Elastomer o-ring seat secured in body with dove-tail groove, Integrated body seat, Non-blow out shaft design. Optimizes space utilization, Lowers installation costs, Reduces pipe supports, Requires less number of man-hours, Unobstructed flow Stable disc at lower flow velocities, No shearing of disc from arm, Non-rotating disc for longer life.

NON SLAM CHECK VALVE

Disc Check Valve is advanced designs 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 flexibly accommodates various types of flange selection. The valves can be fitted in any direction in pipelines. Zero leakage for soft seated valves.

DUAL PLATE CHECK VALVE

The dual Plate Check Valve is an all purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or life check valve. Dual Plate Check Valve has cylindrical body which makes the valve look like any other pipe fitting. A cylindrical body has much more uniform distribution of stress compared to a conventional swing check valve. A cylindrical body of the pressure containing part of the Dual Plate Check Valve can be designed to withstand extreme much to the weight (thickness) of valve. Thus for severe/ rugged loading conditions, these valves have a distinct edge over the conventional valves both in terms of safety and economics besides general versatility. The Dual Plate Check Valve employs two spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by torsion spring action without requiring reverse flow. This design offers the twin advantages of No Water Hammer and Non Slam simultaneously. All features put together make the Dual Plate Check Valve one of the most efficient design. Dual Plat Check Valves are available in wafer design, flanged wafer design and extended design with flanged ends having face to face dimensions as that of a swing check valve.
