Proportional Directional Valve 4WRZ25W8-220-7X/6EG24N9ETK4/V - Bosch Rexroth R900951294

The fewer pilot lines a manifold needs, the shorter the assembly work. The 4WRZ25W8-220-7X/6EG24N9ETK4/V routes pilot supply as well as pilot return internally, so only the four main ports have to be piped, at 220 l/min nominal flow.

Benefits

• Internal pilot oil supply plus internal pilot oil return, no extra pilot lines on the manifold
• Nominal flow 220 l/min, maximum flow 870 l/min
• Maximum operating pressure 350 bar, spool symbol W8
• 3 switching positions, 4 ports to ISO 4401-08-08-0-05
• External electronics at 24 VDC, concealed auxiliary actuation
• FKM seals, weight 18.2 kg

Application

Suited to compact manifolds whose system pressure stays above the required pilot pressure across the whole cycle. Internal routing cuts the number of fittings, therefore the number of possible leak points. HL hydraulic fluid is released.
