Large cylinders need a valve cross section that reverses the oil flow without heavy throttling losses. This pilot-operated directional spool valve in size 25 carries up to 700 l/min at 350 bar operating pressure across three switching positions. Pilot oil supply and return are external, the spool uses symbol E.

When reversing large cylinders and hydraulic motors, rated flow decides how fast the axis starts moving. The H-4WEH25E6X works with 700 l/min at a maximum operating pressure of 350 bar and mounts on an ISO 4401-08-08-0-05 interface.
Benefits
- 700 l/min flow through the size 25 subplate interface
- Maximum operating pressure 350 bar, NBR seals for HL hydraulic fluid
- Three switching positions with spool symbol E and four ports
- External pilot oil supply and external pilot oil return keep the pilot circuit apart from the main circuit
- Solenoid actuation at 24 VDC, connector 3-pole (2 + PE) according to EN 175301-803
- Installed weight 19.66 kg on the ISO 4401-08-08-0-05 interface

Applications
Typical duty is in presses, injection moulding machines and lifting gear where a cylinder with a large oil volume has to move. External pilot oil routing suits plants whose pilot pressure comes from a separate circuit. A 24 V signal on the solenoid is enough to reverse the flow.
