Solenoid controlled pilot operated directional valve (2) Solenoid controlled pilot operated directional valve (2) 3 position valve gasket connection type 3 position valve flange connection type Overview This solenoid controlled pilot operated directional valve is used for operating the solenoid operated directional valve and for controlling start and stop, and movement direction of the hydraulic system with hydraulic pilot signals. Features 1. The improvement of internal coring shape and spool shape of the casing has substantially reduced the flow resistance. 2. For return to neutral of the main valve, the spring center type and pressure-centred type are prepared as standard items. 3. A stroke limiter for adjusting spool stroke of the main valve can be installed. 4. The maximum working pressure is 34.3 MPa (350 kgf/cm 2 ). 1-32
