Parking brake control valve (1) Brake release sequence valve (2) Line from brake release system (3) Port to hydraulic tank (4) Port from pilot oil pressure reducing valveRecovery Bar
The sequence valve ensures that the brake release system is disabled when the engine is running.When the engine is running, pilot oil pressure is available at port (4). The pilot oil pressure will move the spool in brake release sequence valve (1) against spring pressure. When spool in brake release sequence valve (1) moves, oil will flow from brake release system at port (2), through port (3) to hydraulic tank. The brake release system is now disabled.When the parking brake is engaged, there is no pilot oil pressure available at port (4). Spring pressure moves the spool in brake release sequence valve (1) to the normally closed position. Ports (2) and (3) are now blocked. When the brake release system is activated, the oil from the brake release cylinder will release the parking brake.Recovery Hook
