7 PRESSURE ONTROLS Solenoid ontrolled Relief valves These valves are a comination of relief valve and solenoid valve. Piping etween the two is eliminated as the solenoid valves is directly mounted on the relief valve and connected with the relief valve vent. Pump pressure may e unloaded remotely y an electrical signal to the solenoid, or y connecting pilot relief valves to the solenoid valve ports.
