Proportional Directional Valve 4WRZ10E50-7X/6EG24N9EK4/V - Bosch Rexroth R978916341

The 4WRZ10E50-7X/6EG24N9EK4/V meters flow steplessly at a nominal rating of 50 l/min. Upwards 170 l/min are possible, operating pressure stops at 315 bar, control comes from external electronics on 24 VDC.

Benefits

• 50 l/min nominal flow, up to 170 l/min of flow
• Stepless metering to spool symbol E across three switching positions
• Operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05
• Electrical with external electronics, 24 VDC, connector 7-pole (6 + PE) to EN 175201-804
• FKM seals for HL hydraulic fluid, 8.24 kg weight

Applications

Stepless valves of this kind accelerate cylinders gently and brake them under control, for example on feed axes and hoists. The nominal flow of 50 l/min sets the speed that can be reached. The amplifier sits outside the valve, so it has to match the control system.
