Proportional Directional Valve 4WRZ32W8-360-7X/6EG24N9EK4/D3V - Bosch Rexroth R901067989

Some systems take pilot oil from the main circuit yet return it unpressurised into a line of their own. This size 32 proportional valve is laid out for that case with internal pilot oil supply and external pilot oil return, it passes 360 l/min nominal flow and is driven from external electronics.

Benefits

• 360 l/min nominal flow with a maximum of 1600 l/min across the valve
• Internal pilot oil supply with external pilot oil return, so the Y port runs into a dedicated line
• An integrated pressure reducing valve limits pilot pressure at operating pressures up to 350 bar
• Spool symbol W8, ISO 4401-10-09-0-05 port pattern, weight 42.1 kg
• Concealed auxiliary actuation and FKM seals for HL hydraulic fluid

Applications

The valve serves large cylinders in presses, lifting gear and testing machines. Control is handled by external amplifier electronics with a 24 VDC supply. The connector is a 3-pole (2 + PE) type.
