Proportional Directional Valve 4WRZ16W6-180-7X/6EG24N9EK4/V - Bosch Rexroth R901465806

A cylinder that has to start without a jolt and run out without a pressure surge calls for a continuously variable orifice instead of a fixed switching position. The pilot-operated proportional directional valve 4WRZ16W6-180-7X/6EG24N9EK4/V delivers a nominal flow of 180 l/min in size 16 and handles up to 460 l/min as well as 350 bar operating pressure.

Benefits

• Nominal flow 180 l/min, maximum flow 460 l/min in size 16.
• Operating pressure up to 350 bar, FKM seals for HL hydraulic fluid.
• Spool symbol W6 with three switching positions on four ports, version without pressure reducing valve.
• Internal pilot oil supply, external pilot oil return, concealed auxiliary actuation.
• Electrical control with external electronics, 24 VDC, connector 7-pole (6 + PE) to EN 175201-804, weight 11.2 kg.

Application

The valve is fitted in feed axes, injection moulding machines and test rigs where speed and direction of an actuator are guided continuously. Operation requires external amplifier electronics that convert the command value into solenoid current. The concealed auxiliary actuation allows movement during commissioning without an electrical signal.
