Relief valve opens automatically,
relieving system pressure to prevent over pressurization of a system. Process pressure
acts against the bottom of the disc. As pressure exceeds the setpoint for the valve,
established by a spring in most cases, the disk is pushed upward. When system pressure
returns below the valve's setpoint, the spring push back the of the disc forcing it shut.
By adjusting the tension on the spring, the setpoint can be adjusted.
