⚙️ Pressure Reducing Valves (PRV), Pressure Regulators & Reducers | Udhhyog Guide
Pressure control is one of the most important aspects of industrial safety, fluid efficiency, and equipment longevity. Whether you’re managing steam, water, compressed air, or gas lines—a pressure reducing valve (PRV), also known as a pressure regulator or pressure reducer, plays a vital role.
At Udhhyog, we supply high-performance PRV valves and regulators across India. Trusted by HVAC engineers, plant managers, contractors, and OEMs, our valves are used in applications ranging from boiler rooms to commercial buildings.
In this guide, we’ll cover:

🔍 What is a Pressure Reducing Valve?
A pressure reducing valve (PRV) is a control valve that automatically reduces a higher inlet pressure to a lower, stable outlet pressure, regardless of fluctuations in flow or upstream pressure.
Also called:
PRV valve
Pressure regulator
Pressure reducer
It ensures that downstream systems are protected from overpressure, improving system efficiency and safety.
🔩 How Does a Pressure Regulator Work?
The core principle behind a pressure regulator is balance:
It uses a spring-loaded diaphragm or piston
The spring is set to a desired outlet pressure
When inlet pressure exceeds this setpoint, the valve modulates to restrict flow
Once downstream pressure is achieved, it holds steady
💡 In some systems, an external sensing line is used for more precise pressure feedback.
🏭 Applications of PRV Valves
Udhhyog supplies PRV valves to diverse sectors, including:
🔧 Industrial Applications
Steam lines in boiler houses
Water supply for industrial machinery
Oil and gas pipelines
Air compressor systems
Cooling and chilled water loops
🏢 Building Applications
HVAC systems (chillers, AHUs, FCUs)
Domestic and commercial water pressure control
Sprinkler and firefighting networks
RO water treatment units
🧪 Sensitive Flow Systems
Pharmaceutical processing
Laboratories
Food and beverage pipelines
Bottling plants
Wherever constant pressure is needed downstream, a pressure reducer valve is a must.

🧠 FAQs – Pressure Reducing Valves
Q: What is the difference between a pressure reducer and regulator?
A: Both reduce pressure, but regulators offer tighter control and are used in precise applications, while reducers may suit broader flow lines.
Q: Can I use a PRV for steam?
A: Yes, but only specialized steam PRVs with temperature-rated materials like SS or WCB.
Q: Can one valve handle both reducing and sustaining?
A: Yes, we offer dual-function PRVs for this purpose.
Q: Is a PRV the same as a safety valve?
A: No. A PRV controls pressure, while a safety valve relieves excess pressure in emergencies.
