Proportional Directional Valve 4WRZ10W8-25-7X/6EG24N9K4/V - Bosch Rexroth R900972871
Small movements need a small nominal flow. The 4WRZ10W8-25-7X/6EG24N9K4/V controls 25 l/min to symbol W8 and draws its pilot oil from an external circuit. Operating pressure may reach 315 bar and the valve weighs 7.78 kg.

Description
At 25 l/min nominal flow the 4WRZ10W8-25-7X/6EG24N9K4/V resolves even small command value steps. Pilot oil supply and pilot oil return sit outside the valve.
Advantages
- Nominal flow of 25 l/min for slow and finely guided axes.
- External pilot oil supply and external pilot oil return.
- Symbol W8 in three switching positions, total flow up to 170 l/min.
- Operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05.
- Concealed manual override, FKM seals, weight 7.78 kg.
Application
Typical tasks are feed drives, clamping movements and positioning axes at low speed. Because piloting is fed externally, behaviour stays the same even when working pressure changes through the cycle.
