In this article, we’ll explore both the pilot operated non return valve and the wafer type NRV valve, understand their working principles, advantages, applications, and how Udhhyog delivers the best in class products across sectors.

🔍 What is a Non Return Valve (NRV)?

A non return valve, also known as a check valve, allows fluid to flow in only one direction. Its primary role is to prevent reverse flow, which could otherwise damage pumps, contaminate clean lines, or disrupt system operation.

Unlike gate or globe valves, NRVs are automatic. They require no manual actuation or power supply, making them ideal for energy-efficient flow control.

🧠 Understanding the Pilot Operated Non Return Valve

The pilot operated non return valve is a smart evolution in NRV technology. Unlike conventional NRVs that depend purely on flow pressure to open or close, this type of valve includes a pilot mechanism—a control device that senses upstream or downstream conditions to trigger the valve operation.

✅ Key Features of Pilot Operated NRVs:

Precise Control: Opens only when system conditions meet specific pressure criteria.

No Slamming: Prevents sudden shut-off, reducing water hammer and shock.

Failsafe Mechanism: Designed to lock or unlock under set pilot pressures.

Remote Actuation: Some models allow manual or pneumatic overrides.

🔧 Applications:

High-pressure pumping stations

Water distribution networks

Oil and gas flow lines

Fire suppression systems

Marine and offshore platforms

These valves are especially valuable where flow reversal could damage critical equipment, or where automated safety control is required.

🧩 Wafer Type NRV Valve – Compact, Reliable, and Efficient

The wafer type NRV valve is one of the most space-efficient non return valves. It is designed to be sandwiched between two flanges in a piping system.

Instead of using a large body and bonnet like conventional valves, wafer NRVs consist of a flat disc or dual plates that open and close based on flow pressure.

✅ Benefits of Wafer Type NRV Valves:

Space Saving: Ideal for compact setups or where installation space is limited.

Lightweight Design: Reduces pipeline load and shipping cost.

Quick Installation: No need for special fittings—fits between existing flanges.

Low Pressure Drop: Disc design allows smooth, streamlined flow.

🔧 Typical Use Cases:

HVAC systems

Chemical dosing lines

Irrigation and agriculture

Cooling towers

Food and pharma processing units

At Udhhyog, our wafer type NRV valves are available in cast iron, stainless steel, bronze, and PTFE-lined variants to suit a wide range of fluids.
