Running a small servo axis to position calls for a valve that still resolves cleanly at 5 l/min. The 4WS2EM10-5X/5B11XHT315K31EV meters directly actuated with internal spool position feedback, taking its pilot oil externally so pilot pressure stays clear of a fluctuating working pressure.

Total price
A small servo axis loses accuracy the moment its valve stops resolving in the low flow range. This directly actuated servo valve in size 10 is rated at 5 l/min nominal flow, passes 9 l/min at most, and works up to 350 bar operating pressure.
Benefits
- 5 l/min nominal flow keeps resolution at slow feed rates, with 9 l/min as the maximum
- External pilot oil supply with internal pilot oil return, so pilot pressure ignores load steps in the P line
- Internal spool position feedback, driven by analog command value 30 mA/85 from external electronics on 24 VDC
- 350 bar operating pressure with FKM seals on HL hydraulic fluid
- ISO 4401-05-05-0-05 connection diagram, subplate mounting, 3 switching positions, 3.86 kg

Application
Test benches, materials testing machines, position axes with small cylinders under closed loop position or force control. External pilot supply pays off where system pressure dips in the cycle while valve dynamics have to stay constant. Mounting is on a subplate to ISO 4401-05-05-0-05.
