Total price
A cooler in the return line builds back pressure that can disturb the pilot stage. The 4WRLE25V1-400L-4X/MPY/24A1 therefore draws pilot oil internally from P while routing the pilot return separately through Y, at 400 l/min rated flow and 350 bar.
Benefits
- Internal supply with external pilot return keeps the pilot stage clear of tank back pressure.
- Spool symbol V1 with 3 switching positions, linear curve with spool position feedback.
- 400 l/min rated flow in size 25, maximum flow 1250 l/min.
- Analogue command value plus minus 10 V on the on-board electronics, 24 VDC supply.
- Subplate mounting ISO 4401-08-08-0-05, CE marked, NBR seals, 19.42 kg.
