Safety Valve /Pressure Relief Valve

Pressure Relief Valve

Safety Valves / Pressure Relief Valves are critical protective devices used to safeguard piping systems, equipment, and personnel from overpressure conditions. They automatically release excess pressure when the system pressure exceeds a preset limit and reclose once normal pressure is restored, ensuring safe and continuous operation.

These valves are widely used in instrumentation lines, pressure vessels, boilers, compressors, and process systems across industries such as oil & gas, chemical, petrochemical, power generation, and pharmaceuticals. Designed for high reliability and accurate set pressure control, safety and pressure relief valves are manufactured from robust, corrosion-resistant materials to perform effectively under high pressure and temperature conditions, making them essential components in any pressure-controlled system.

Pre-Calibrated Design or Range Setting

We offer two flexible configuration options for our Safety Valves: Pre-Calibrated Design and Range Setting, allowing you to choose what best suits your application.

In the Pre-Calibrated Design, safety valves are factory-set and calibrated to your specified set pressure. Even under continuous operation, the valve consistently opens at the defined pressure. This reliability is ensured by our specially fabricated high-tensile spring, designed to maintain accuracy and long-term performance.

With the Range Setting option, the safety valve is supplied with a defined minimum and maximum pressure range. The required set pressure can be easily adjusted on site using the adjustment screw provided at the top, offering flexibility for systems where operating conditions may vary.
