Directional Spool Valve H-4WEH25E6X/6EG24SK4QM0G24SO12 - Bosch Rexroth R900946305

Separate pilot oil paths keep the pilot pressure independent of the pressure in the main circuit. The H-4WEH25E6X/6EG24SK4QM0G24SO12 uses external pilot oil supply and external pilot oil return while switching up to 700 l/min to symbol E.

Benefits

• External pilot oil supply and return, so the pilot pressure can be chosen freely.
• Maximum flow of 700 l/min in size 25 to ISO 4401-08-08-0-05.
• Operating pressure up to 350 bar at a mass of 18.8 kg.
• Symbol E with 3 switching positions and 4 ports.
• Solenoid actuation at 24 VDC through a connector 3-pole (2 + PE) according to EN 175301-803.
• NBR seals for HL hydraulic fluid.

Technical data

Applications

The valve is used in systems with their own pilot oil circuit, for instance presses with a separate pilot pump or power units whose main pressure varies widely. The pilot pressure stays stable there even when the main circuit is unloaded. NBR seals are fitted for mineral oil of class HL.
