Proportional Directional Valve 4WRTE10V50L-4X/6EG24ETK31/A1V - Bosch Rexroth R978919621
An axis running at 50 l/min needs no more than size 10, provided it works under position control. The 4WRTE10V50L-4X uses spool symbol V, processes the ±10 V command value in its on-board electronics and takes pilot oil internally, so only four ports need piping.

Description
An axis with an oil demand of around 50 l/min does not need a big valve, it needs an accurate one. This pilot-operated size 10 proportional valve works with spool symbol V, internal spool position feedback and on-board electronics that evaluate the ±10 V command value at the unit itself.
Benefits
- 50 l/min nominal flow, up to 170 l/min across the valve
- Spool symbol V with a linear characteristic curve and internal spool position feedback
- On-board electronics, ±10 V command value, 24 VDC supply
- Internal pilot oil supply and internal pilot oil return
- ISO 4401-05-05-0-05 port pattern, FKM seals, weight 9.5 kg
Applications
Typical applications are positioning axes on machine tools, clamping devices and small test cylinders. The ISO 4401-05-05-0-05 subplate mounting is widespread at size 10 and allows replacement without rework. An operating pressure of up to 350 bar covers the usual system pressures.
Manufacturer
Bosch Rexroth identifies the valve by material number R978919621.
