Dual Plate Check Valve

dual-plate check valves are wafer-type valves with a short overall length. Their excellent hydrodynamic properties result in very low pressure losses. Their lower weight brings advantages during installation, transport and storage.
They are suitable for liquid, gas and steam in heating, air conditioning and cooling systems. However, they can also be used in steam and condensate systems, in the water supply, and in oil and natural gas pipes.
With the suitable springs, they can be installed in any position.
