Our safety relief valve is fitted in vessels to prevent an undue rise in pressure. Whenever the vacuum is build, the safety relief valve gets actuated and there is a rapid opening or pop up action to release the pressure. Used in various industries, our safety valve is available in sizes to suit the requirements of our clients.

We are a highly acclaimed firm engaged in offering superior quality Safety Relief Valve to the clients. We manufacture the Safety Relief Valve using cutting-edge technology and graded material. The Safety Relief Valve offered by us is rigidly constructed, dimensionally accurate and durable. We offer precision-engineered Safety Relief Valve as per customer specifications and requirements.

Conventional Safety Relief Valves are those which work on simple working principle of force balance. The operation of a conventional spring-loaded PSV/SRV is based on a force balance principle. Under normal operating conditions, until the pressure at the inlet is below the set pressure or opening pressure, the disc is seated on the nozzle preventing flow through the nozzle. When the pressure at inlet exceeds set pressure/opening pressure, then pressure force on the bottom of disc overcomes the spring force, lifts the disc affecting opening of valve and relieves the excessive pressure in system.   When the inlet pressure drops sufficiently below the set pressure / opening pressure, the spring force overcomes the pressure force, the disc re-seats on nozzle and valve closes.   In REGPORT conventional Safety Relief Valves, an adjustable Blow Down Ring is provided for adjusting the opening in the annular orifice, thus controlling the pressure build-up in the huddling chamber. This controlled pressure build-up in the huddling chamber will overcome the spring force causing the disc to move away from the nozzle seat, and the valve will pop open. With this, fine adjustment in over pressure and blow down can be done. As a standard, unless specified, all our Safety Relief Valves are Full Nozzle Full Lift and tested for 10% over pressure.
