High Pressure Relief Valve, PRV, Spring Type, Size: 2" Fig 1502, 3" Fig 1502 5000PSI, 10000PSI, 15000PSI, STD and Sour Service

VigorPetro's Pressure Relief Valves (PRV) are direct acting, relying on the system’s hydraulic pressure to open when the preset force of the spring is exceeded. The 2” valve’s operation is a simple balance between the spring loaded keeper which holds the ball in the seat and the inlet liquid pressure acting on the ball. The spring pressure is set by tightening the hex bolt on top which pushes on the keeper, and, in turn, compresses the Belleville springs that forces the keeper on the ball. When the inlet fluid pressure rises and overcomes the set
spring pressure, the ball is lifted off its seat thereby discharging fluid through the outlet end. Once the pressure of the inlet fluid falls below the set spring pressure, the ball will be pushed back onto its seat and the fluid can pass downstream.
