Solenoid Controlled Pilot Operated Directional Valves Solenoid Controlled Pilot Operated Directional Valves These valves are composed of a solenoid operated pilot valve and a pilot operated slave valve. When a solenoid is energised the pilot valve directs the flow to move the spool of the slave valve, thus changing the direction of flow in the .
