WebWith pilot operation, the valve uses the inlet pressure to help move the spool. The valve contains a small internal pneumatic cylinder that actuates the spool. The filling and emptying of this cylinder is controlled by the actuator, for example a solenoid. 5/2-way valves are usually pilot operated. The valve’s main parts are: Housing Seals Piston WebPilot valves are very useful because they allow a small and easily operated feed to control a much higher force to operate. It is even useful when a solenoid is used to operate the pilot valve. Minimum oil pressure needs to be ensured for all operating conditions of the directional control valve ( DCV ).
