1 / 2Dual-Plate Check Valve — product view
Dual-Plate Check Valve
Dual-plate model with a GG25 body and EPDM seal
A pair of plates admits forward flow and closes against reversal. Do not assume the same dimensions or head loss as a disc or single swing check valve. Assess line velocity, pressure drop and compatibility of the EPDM seal with the liquid.
Final selection requires the complete product code and the service conditions.
UNDERSTAND THE APPLICATION
A solution for your application.
Application areas
Pump discharge backflow control · Water distribution headers
Selection considerations
Verify installation orientation, flow velocity and closing conditions.
Opening and stable operation depend on the line conditions. Consider the risk of reverse flow together with flow direction and the proposed installation orientation.

Frequently asked questions
How do I check seal compatibility?+
State the fluid composition and operating temperature; EPDM is not suitable for every chemical environment.
Will this valve eliminate water hammer?+
Not by itself. Evaluate pump deceleration, line length and valve closure dynamics together.
What should I verify before specifying Truevalve Dual-Plate Check Valve?+
Confirm the permissible orientation and pressure–temperature limits in the selected check valve’s technical document. Assess the effect of rapid closure on upstream and downstream pressures at system level.
What should I include in my quotation request?+
Line size, connection and orientation; Fluid, temperature and flow range; Reverse-flow and closure conditions. For replacement equipment, also provide the nameplate and connection dimensions.
Where can I check the technical drawing and dimensions?+
Open the manufacturer PDF in the Technical Documents section. Match the relevant entry to the product type, nominal size and variant code. Not every option in a family catalogue belongs to the same product.
