PRODUCT INTRODUCTION


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.

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. It is also referred as SILENT CHECK VALVE.

The valve dual plate check valve design conforms to APS 594 as well as API 6D except face to face dimensions of ANSI 125 cast iron valves of sizes 65mm (2½”) to 600mm (24”). Valve inspection and testing conforms to API 598.

MVS Dual Plate 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.

Features

Light Weight thus easier handling and self supporting.

More compact & Structurally sound design.

Same valve can be installed horizontally or vertically.

Only Check Valve which can be installed for flow upside down due to spring assisted closure.

Low Pressure Drop and reduced Energy Loss irrespective of Pressure Ratings.

Streamlined flow – way.

Efficient and Positive sealing under most flow and pressure conditions. Valve close before flow reversal, at zero velocity.

Inherently Non-Slamming. No external devices / attachments required.

Water Hammer almost non-existent.

Long life and trouble-free operation.
