Balanced Safety Relief & Plug Valves – Top Manufacturers & Valve Selection Guide in Delhi
In high-pressure systems, safety, precision, and flow control are critical. That’s where balanced safety relief valves and balanced plug valves come into play. These valves are designed to handle pressure fluctuations, back pressure, and provide consistent performance in demanding environments.
As a trusted valve manufacturer and supplier in Delhi, Udhhyog delivers high-quality, pressure-tested valves suitable for steam, gas, oil, and industrial process systems.
This article offers a complete guide to balanced valve types, their functions, selection tips, and price overview, along with why Udhhyog is your go-to supplier.
What is a Balanced Safety Relief Valve?
A balanced safety relief valve is a pressure relief device used to protect systems from overpressure while compensating for back pressure through the use of a bellows or diaphragm.
Key Features:
Maintains set pressure even with varying back pressure
Ideal for compressible fluids like gas and steam
Designed with bellows or piston seals to isolate spring chamber
Applications:
Boilers
Pressure vessels
Air compressors
Chemical reactors
What is a Balanced Plug Valve?
A balanced plug valve is a type of valve where internal pressure is equalized across the plug to reduce torque and wear during operation. It provides tight shutoff and easy control.
Key Features:
Low operating torque
Suitable for on/off and throttling services
Common in chemical plants, power plants, and oil terminals
Types of Balanced Safety Relief Valves
🔹 Balanced Bellows Safety Relief Valve
Features a flexible bellows to neutralize back pressure effects
Suitable for corrosive and toxic services
🔹 Pilot-Operated Relief Valve (Balanced Type)
Works under low pressure until the pilot detects overpressure
Ideal for high-capacity applications
🔹 Balanced Spring-Loaded Relief Valve
Uses spring pressure to maintain set point
Isolated spring chamber maintains accuracy
Types of Balanced Plug Valves
🔸 Lubricated Plug Valve (Balanced)
Lubricant layer minimizes torque and wear
Used in hydrocarbon and gas lines
🔸 Non-Lubricated Plug Valve (Pressure Balanced)
Uses pressure-balanced sleeves or elastomers
Maintenance-free and longer lifespan
🔸 Multi-Port Plug Valve (Balanced Type)
Diverts flow between multiple ports
Ideal for manifold systems
