Dual Plate Check valve – NRV

A Dual Plate Check valve, also known as a Non-Return Valve (NRV), is a type of valve used to ensure fluid flows only in one direction. It consists of two plates that swing open on hinges to allow flow in the forward direction and automatically close to prevent reverse flow. This design provides efficient operation with minimal pressure drop and reduced water hammer effect. Dual Plate Check valves are commonly used in various industries to maintain fluid flow control and prevent backflow.
