Proportional Directional Valve 4WRZ25E1-220-7X/6EG24N9K4/V - Bosch Rexroth R900957218

Where a manifold already carries a pilot oil rail, the valve is tied into it on both sides while the nominal stage follows the axis. On the 4WRZ25E1-220-7X/6EG24N9K4/V that means 220 l/min nominal flow, spool symbol E1 as well as 18.2 kg of weight.
