In-Flight Refuelling Probe Selector Valve

Multi-way hydraulic directional control valve. Rip-stop, failure tolerant aluminum alloy manifold design, featuring four spool and sleeve selectors.
Electrical actuation of the Selectors by means of five Solenoid Pilot Valves.

• Selector for the Door operation (four ways, two positions, ball retained).
• Selector for the Probe operation (four ways, three positions, spring centered).
• Selector Shut-off for the actuation logic consensus.
• Dump Valve Selector, for emergency deployment, with separation between two independent hydraulic systems.
