Pressure Relief Valves
Sandur Fluid Controls Pvt. Ltd. offers a comprehensive range of Pressure Relief Valves engineered to protect pipelines, pumps, pressure vessels, tanks, boilers, compressors, and industrial process systems from excessive pressure conditions. Designed with precision engineering and reliable pressure control mechanisms, our valves ensure safe, stable, and efficient operation across demanding industrial applications.
These valves automatically release excess pressure when system pressure exceeds preset limits, preventing equipment damage, system failure, safety hazards, and costly downtime.
Our Pressure Relief Valves are widely used in chemical processing plants, water treatment systems, oil & gas facilities, pharmaceutical plants, HVAC systems, food & beverage industries, power plants, marine applications, and industrial automation systems.
Available in spring-loaded, pilot-operated, direct-acting, and customized configurations, these valves provide reliable overpressure protection and long operational life.
A Pressure Relief Valve (PRV) is a safety device designed to automatically relieve excess pressure from a system when pressure exceeds a predetermined set point.
The valve opens automatically during overpressure conditions and safely discharges excess fluid, gas, steam, or air to protect connected equipment and piping systems.
Once normal operating pressure is restored, the valve closes automatically to resume normal operation.
Pressure Relief Valves are critical safety components in pressurized systems where maintaining safe operating pressure is essential.
