Proportional Directional Valve 4WRZ32W8-360-7X/6EG24N9EK4/M - Bosch Rexroth R900729111

A weight of 25 kg at 360 l/min nominal flow shapes how the valve is handled and installed. The 4WRZ32W8-360-7X/6EG24N9EK4/M sits on the ISO 4401-10-09-0-05 pattern and works with internal pilot supply and external return.

Benefits

• 25 kg weight at 360 l/min nominal flow, transport and mounting have to be planned accordingly.
• Internal supply, external pilot oil return, the pilot stage is relieved independently of back pressure in the tank channel.
• Throughput up to 1600 l/min at 350 bar, reserve for rapid traverse phases of large cylinders.
• Spool symbol W8, 4 ports, 3 switching positions to ISO 4401-10-09-0-05.
• Concealed auxiliary actuation, NBR seals, laid out for HL hydraulic fluid in an industrial circuit.
