Rexroth valve R900954656 4WRZE16E1-150-7X/6EG24N9ETK31/A1D3V With de-energized solenoids (5, 6), the main control spool (11) is held in the central position by means of the centering spring (12) The main control spool (11) is controlled by the pilot control valve (9); the main control spool is proportionally moved, e.g. by actuating solenoid "b" (6) → The control spool (2) is moved to the right, pilot oil enters the pressure chamber (13) via the pilot control valve (9) and deflects the main control spool (11) proportionally to the electric input signal → Connection from P to A and B to T via orifice-type cross-sections with progressive flow characteristics Pilot oil supply to the pilot control valve internally via port P or externally via port X Switching off the solenoid (6) → The control spool (2) and main control spool (11) are moved back into the central position Depending on the spool position, flow occurs from P to A and B to T or P to B and A to T (R) An optional manual override (14 and 15) can be used to move the control spool (2) without solenoid energization. |
