Our pressure relief valve survey consists of the following:
- Location of the valve leaks: We have proprietary testing equipment which will detect even the smallest of leaks. We can locate your leaks under normal operating conditions
- Tagging: Upon detection, the valve is tagged with a numbered metal tag
- Computer printout (Excel spreadsheet): Upon completing of the survey, you will receive a report with the following information: valve leaking, location of valve, tag number, and estimate system process loss.
The function of a pressure relief valve is to protect pressure vessels, piping systems, and other equipment form pressures exceeding their design pressure by more than a fixed predetermined amount. A pressure relief valve must be capable of operating at all times, especially during a period of power failure; therefore, the sole source of power for the pressure relief valve is the process fluid.
Pressure relieve valve (PRV) is a type of valve used to control or limit the pressure in a system or vessel which can build up for a process upset, instrument or equipment failure, or fire.
Definition of PRV
Pressure relieve valve (PRV) is a type of valve used to control or limit the pressure in a system or vessel which can build up for a process upset, instrument or equipment failure, or fire. The pressure is relieved by allowing the pressurized fluid to flower from an auxiliary passage our of the system. The relief valve is designed or set to open at a predetermined set pressure to protect pressure vessels and other equipment from being subjected to pressures that exceed their design limits. When the set pressure is exceeded, the relief valve becomes the “path of least resistance” as the valve is forced open and portion of the fluid is diverted through the auxiliary route.
