Pressure Safety Relief Valve

Nivz Valves & Automation manufacturing range all Pressure Safety Relief Valves are designed as per API 526. They also conform to ASME Section – VIII. Dimensions of valves meet to API 521/521. Metal seated Safety Valves Testing is carried our as per API 527 for Set Pressure & Leakages.

A Safety Relief Valve is a mechanical, self actuating, pop design, spring loaded angle type valve, which is being used for the automatic release (on a set pressure) of a substance from a Pressure Vessel, Boiler, Overpressure of Pipeline or any Industrial System when the Pressure or Temperature exceeds required limits.

Pressure Relief valves also being used to Control the Pressure in an Industrial System, Process Pipeline or Pressure Vessel which can develop by a failure of equipment, instrument or process upset.

Safety Valve also known by the name of Pressure Relief Valve (PRV) and Pressure Safety Valve (PSV). Other names of Safety Valves are Safety Relief Valve, Thermal Relief Valve, Relief Valve, Spring Loaded Safety Valve, Angle Type Safety Valve, Pilot Operated Safety Relief Valve and Low Pressure Safety Relief Valves.

The difference in between Pressure Safety Valve (PSV) and Pressure Relief Valve is Pressure Safety Relief Valve have provided a manual lever with a cap to relieve the pressure in case of emergency.

Mostly two types of protection encountered in Industries which are Flow Protection & Thermal Protection. Flow protection is done by the using of Safety Relief Valves and Thermal Protection by Thermal Relief Valve.
