Proportional Directional Valve 4WRZ25W9-220-7X/6EG24N9ETK4/D3M - Bosch Rexroth R901335483

Where neither pilot supply nor pilot return is routed separately, the valve has to handle both itself. The 4WRZ25W9-220-7X/6EG24N9ETK4/D3M works with internal supply and internal return and moves 220 l/min nominal flow.

Benefits

• 220 l/min nominal flow at an operating pressure of up to 350 bar.
• Pilot-operated spool valve in size 25, throughput up to 870 l/min.
• Pilot oil supplied internally and returned internally in this version.
• External electronics take over the control, 24 V DC supply.
• Symbol W9, 20.68 kg, hydraulic fluid HL, NBR seals.

Applications
