DUAL CHECK VALVE
DUAL CHECK VALVE
( Non-Return Valve )
Structural features
Two plate structure (Dual Plate)
 There are two crescent-shaped plates inside the valve that open when the flow is flowing and quickly close with the force of a spring when the flow is reversed.
Fast response speed and low water hammer generation.
Compact design
 Shorter face-to-face distance than conventional swing check valves. Space-saving, suitable for tight installation spaces.
Lightweight
 It is easy to handle because the structure is simple and the materials are minimal, making it light.
Easy to install and maintain.
Low pressure loss
 Both plates open easily in the direction of fluid flow, and pressure loss is small depending on the flow rate.
Water Hammer Reduction
 Reduces water hammer with quick plate closing and spring operation. Effective in protecting pipes and equipment when the pump stops (shock reduction)
