Specification of this Stainless Steel Check Valve Dual Plate Check Valve
Wafer Type Dual Plate Check Valves are maintained open by the flow of fluid in the forward direction and are closed by back pressure of the fluid or by the weight of the closing mechanism or by a spring force. Available in Various designs and sizes. The range of these valves available from 50mm to massive units of 1600mm dia. All features put together make the valve as the most efficient & versatile design.The Dual Plate Check Valve employs two-spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place. This design offers the twin advantages of No Water Hammer and Non Slam together. All the features put together make Dual Plate Check Valve as the most efficient & versatile design. It is also referred to as SILENT CHECK VALVE. 
Parameters of this Stainless Steel Check Valve Dual Plate Check Valve

Features

Small in size, light in weight, compact in structure, easy in maintenance.
Two torsion springs are used excreting on each of the pair valve plates. Which close the plates quickly
and automatically.
