Total price
Large cylinders in presses and lifting gear call for flows that require a pilot stage. The H-4WEH25HP6X/6EG24N9S2K4 is a pilot operated size 25 spool valve for up to 700 l/min at 350 bar, switched by a 24 V DC solenoid.
Benefits
- 700 l/min flow through the size 25 interface to ISO 4401-08-08-0-05.
- 350 bar maximum operating pressure in the pilot operated design.
- Spool symbol P across three switching positions, with four ports for the main circuit.
- External pilot oil supply and external return, so pilot pressure is routed independently of the main circuit.
- 24 V DC at the 3-pole connector (2 + PE), at a valve weight of 20.34 kg.
