Solenoid controlled pilot operated directional valve

The solenoid controlled pilot operated directional valve is a two-stage assembly explicitly designed for high-capacity hydraulic systems. Standard electromagnetic force is insufficient to shift large spools against massive fluid pressure. Therefore, this valve utilizes a small, direct-acting solenoid valve (the pilot valve) mounted on top to direct control fluid, harnessing the system's own hydraulic pressure to shift the massive main spool below.
