Best Reflux Valve Manufacturer in Delhi â Features, Diagram & Price Guide
 In every fluid transport or pumping system, preventing reverse flow is essential to avoid system damage and maintain efficiency. Thatâs 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.
Itâs 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
â  One-Way Flow Control â Prevents reverse flow in pressurized systems. â  Durable Build â Manufactured using cast iron, ductile iron, or stainless steel. â  Leakproof Design â Tested under hydrostatic pressure. â  Smooth Operation â Low-pressure drop and quick closing mechanism. â  Corrosion-Resistant Coating â Ideal for water, sewage, and industrial fluids.
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

What is a Reflux Valve? Diagram, Price List & Best Supplier in Delhi
In fluid and pipeline systems, ensuring one-way flow is crucial to avoid backflow and system damage. Thatâs where reflux valves come into play. Also known as non-return valves (NRVs), reflux valves are used in water supply lines, sewage systems, pumping stations, and more.
As a trusted reflux valve manufacturer and supplier in Delhi, Udhhyog offers premium-quality, long-lasting valves for municipal, commercial, and industrial use.
This article explains what a reflux valve is, how it works, its diagram, pricing, and where to get the best reflux valve in Delhi.
What is a Reflux Valve?
A reflux valve is a type of non-return valve that allows fluid to flow in only one direction and automatically prevents backflow. It is typically installed in pumping systems, especially on the delivery side of pumps.
Reflux Valve is Also Known As:
NRV (Non-Return Valve)
One-Way Valve
Check Valve
Non-Return Check Valve
Reflux Valve Working Principle
The valve has a disc or flap that opens when the fluid flows forward. When reverse flow occurs, the disc automatically closes due to gravity or spring action, preventing backflow.
This makes reflux valves essential in vertical pipelines and pumping applications, especially where system damage due to reverse pressure must be avoided.
Reflux Valve Diagram
The reflux valve diagram typically includes:
Valve body
Disc/flap or check plate
Flow arrow (direction indicator)
Spring (in spring-loaded variants)
The diagram helps engineers and technicians understand installation orientation, internal structure, and maintenance procedure.
Types of Reflux Valves
