Description & Features

The dual plate wafer check valves has two spring loaded half-moon shaped discs that rotate about their shaft. The disc plates are kept shut by the torsion spring. When fluid flows in the forwards direction, the pressure of the fluid causes the disc plates to hinge open, allowing flow. Dual plate check valve is closed by the spring as soon as flow ceases, before any reverse flow can occur.

● Light weight, versatile design, 80 to 90% lighter than conventional full-body check valves.

● Reduces pipe supports, simplifies piping, easier, less costly installation.

● Reduced thermal and seismic considerations.

● No need for additional expensive support.

● Optimum space utilization; simplified piping.

● Spring-loaded, double door design has low cracking pressure.

● Discs open 85° to ensure positive closing.

● Materials and trims available for all services within temperature range.
