Pilot operated, 3-way normally closed hydraulic relay valve. It is designed to relay a hydraulic supply from the inlet port to the outlet port when the pilot signal is applied and to block the inlet and then open the outlet to the bleed port when the pilot signal is removed.

Pilot operated, 3-way normally closed hydraulic relay valve. It is designed to relay a hydraulic supply from the inlet port to the outlet port when the pilot signal is applied and to block the inlet and then open the outlet to the bleed port when the pilot signal is removed. The hydraulic supply may be relayed without a pilot signal by pulling up the handle in the bypass condition. The handle may be pinned in this position for a continuous override condition, but the pin must be removed for normal operation to occur
