How Does A Hydraulic Pressure Relief Valve Work?

A hydraulic pressure relief valve, or a pressure relief valve or safety valve, is a crucial component in hydraulic systems. Its primary function is to protect the system from overpressure by releasing excess fluid when the pressure exceeds a predetermined limit. Let’s explore how a hydraulic pressure relief valve works:

  1. Valve Operation:
    • A hydraulic pressure relief valve typically consists of a valve body, a spring-loaded control element, and an adjustable spring.
    • The valve body contains an inlet port, an outlet port, and a control chamber connected to the spring-loaded control element.
  2. Pressure Setting:
    • The pressure relief valve is pre-set or adjustable to a specific pressure level.
    • The pressure setting determines the threshold at which the valve opens to relieve excess pressure.
  3. Pressure Monitoring:
    • The pressure is monitored continuously when hydraulic fluid enters the valve through the inlet port.
    • If the pressure exceeds the pre-set limit, the control element is activated to relieve the excess stress.
  4. Control Element Activation:
    • The control element, often a spring-loaded poppet or spool, responds to the excessive pressure.
    • As the pressure rises beyond the set point, the force exerted on the control element exceeds the opposing party of the spring.
  5. Opening of the Valve:
    • When the force on the control element exceeds the spring force, the valve opens, creating a path for fluid to bypass the main flow path.
    • The excess fluid flows through the valve and exits via the outlet port, relieving the pressure in the system.
  6. Pressure Reduction:
    • As the excess fluid is diverted through the relief valve, the pressure in the system decreases.
    • The valve remains open until the pressure drops below the pre-set limit.
  7. Pressure Stabilization:
    • Once the pressure decreases below the setpoint, the control element returns to its original position, closing the valve.
    • The hydraulic system resumes regular operation, with the pressure controlled within the desired range.
