DUAL PLATE
Dual plate check valves are used to protect installations against backflow. They are entirely operated by reaction of flow and they do not require any external actuation.
The main advantages of dual plate check valves vs swing check valves are: lightweight, short dimensions. Moreover, line shock is reduced or eliminated. Due to the reduced face to face this check valve can be mounted vertically or horizontally thanks to a return spring.
Dual check valve can be designed as wafer, lug or flanged type.

dual-plate check valves are designed especially for systems or applications where there is low pressure drop.
These check valves prevent backflow in horizontal and vertical pipelines. They are wafer-type valves with a double swing design, two hinge pins and four springs.
dual-plate check valves can be used with a wide range of liquid, gas and vapor systems.
Due to better flow performances, smaller installation space, lower weight and easier installation, dual plate check valves are widely used in the flow control industry. Neway dual plate check valves are in compliance with API 594.
