Description

This modular stack valve is designed to help block oil movement both from the control valve or from the actuator. Typically used with Proportional valves with Zero-Lap type spool configurations that could allow oil movement when the system is shut down.

This valve will block flow when de-energized and will allow bi-directional flow when energized.

Both the A and B work ports incorporate a 2-way, 2-position bi-directional, normally closed poppet type solenoid valve. Energizing the solenoid will allow full flow to the system.
