Reflux valves are crucial in pumping and pipeline systems, ensuring fluid flows in one direction while preventing backflow. These valves are especially useful in water supply systems, sewage lines, fire pipelines, and industrial applications.
As a top reflux valve manufacturer and supplier in Delhi, Udhhyog provides durable and efficient valves made from cast iron, ductile iron, and stainless steel. This guide explains what reflux valves are, their alternate names, common uses, and offers a price comparison across sizes and materials.
What is a Reflux Valve?
A reflux valve is a type of non-return valve (NRV) designed to allow fluid to flow in only one direction. It blocks reverse flow automatically when the flow pressure drops or reverses, preventing damage to the pump and pipeline system.
These valves are often installed on the outlet side of pumps in vertical or horizontal pipelines.
Alternate Names for Reflux Valves
Reflux valves are commonly known as:
Non-Return Valve (NRV)
Check Valve
Backflow Preventer
One-Way Valve
Anti-Return Valve
While the names differ across industries and countries, the core functionality remains the same: blocking reverse flow.
Uses and Applications of Reflux Valves
Reflux valves serve critical functions across many sectors. Here’s where they’re typically used:
✅ 1. Water Supply Systems
To prevent back pressure and contamination in clean water lines.
✅ 2. Sewage and Drainage Lines
Protects pumping stations from sewage backflow, especially during power failures.
✅ 3. Fire Fighting Pipelines
Ensures pressurized water flows only in one direction in sprinkler systems.
✅ 4. Pump Delivery Pipes
Stops water hammer and pump reversal due to sudden shutdown.
✅ 5. Industrial Processing Units
Used in oil, chemical, and fluid processing plants to maintain flow direction.
✅ 6. Irrigation Systems
Helps control flow in agricultural pumping units and canal systems.
Types of Reflux Valves Available at Udhhyog
🔹 Swing Type Reflux Valve
Simple flap design.
Suitable for low-pressure water pipelines.
🔹 Lift Type Reflux Valve
Offers better sealing and quicker shutoff.
Used in vertical pipelines and high-rise buildings.
🔹 Spring-Loaded Reflux Valve
Spring pushes the disc back in place for quick closure.
Ideal for vertical or inclined installations.
🔹 Dual Plate Check Valve
Two spring-loaded plates close quickly.
Used in industrial and chemical systems.
Reflux Valve Material Options
Cast Iron (CI): Most cost-effective, used in water systems.
Ductile Iron (DI): Stronger and more flexible than CI.
Stainless Steel (SS): Best for corrosive environments, like chemicals.
