In every fluid transport or pumping system, preventing reverse flow is essential to avoid system damage and maintain efficiency. That’s where the reflux valve, also known as a non-return valve (NRV) or check valve, plays a crucial role.
As the leading reflux valve manufacturer in Delhi, Udhhyog supplies a wide variety of reflux valves made from CI, DI, and SS for use in municipal water systems, sewage pipelines, firefighting systems, and industrial applications.
This article will guide you through the key features of reflux valves, their diagram, and provide a complete price guide for Delhi buyers.
What is a Reflux Valve?
A reflux valve is designed to allow fluid to flow in one direction and automatically block flow in the reverse direction. I
t protects pumps and pipelines from the effects of back pressure or reverse flow.
It’s most commonly installed on the delivery side of pumps and is crucial in systems where flow reversal could cause flooding, contamination, or equipment damage.
Key Features of Udhhyog Reflux Valves
✅ One-Way Flow Control – Prevents reverse flow in pressurized systems.

Reflux Valve Diagram & Working Principle
The reflux valve operates with a swing-type disc or spring-loaded mechanism. As water or fluid flows forward, it pushes open the disc. When flow stops or reverses, the disc automatically closes, blocking backflow.
Components:
Valve Body
Flap or Disc
Hinge (for swing type)
Spring (for spring-loaded models)
Seat Ring
The diagram visually represents the internal mechanism, direction of flow, and closure method—critical for system designers and installers.
