NRV (Reflux Valves)

A Non-Return Valve (NRV), commonly known as a reflux valve, is a one-way flow control device that allows fluid or gas to flow in only one direction. It prevents backflow or reverse flow in a pipeline or system, ensuring that the substance moves in the intended direction and doesn’t flow backward. Reflux valves are essential for maintaining system efficiency and safety by preventing unwanted reversals in flow.

A reflux valve, also known as a Non-Return Valve (NRV) or check valve, is a mechanical device designed to control the flow of fluids within a piping system by permitting the fluid to flow in one direction while preventing it from backflowing in the opposite direction. These valves play a crucial role in various industrial, commercial, and residential applications, ensuring the safe, efficient, and controlled transfer of liquids or gases.
Reflux valves come in various designs and configurations to suit specific requirements and applications, but they all share a common function: to prevent the reverse flow of fluid, which can be detrimental in many cases. Here's a more detailed description of reflux valves:
