Directional Spool Valve H-4WEH25E6X/6EG24N9SK4 - Bosch Rexroth R900925543

NBR seals and HL hydraulic fluid define the media range of this pilot-operated size 25 valve. The spool with symbol E switches three positions across four ports, the valve passes up to 700 l/min and holds 350 bar operating pressure. The control circuit lies entirely outside.

Benefits

• NBR seals for HL hydraulic fluid
• Spool symbol E with three switching positions across four ports
• 700 l/min flow at 350 bar operating pressure
• External pilot oil supply and external return
• Subplate mounting to ISO 4401-08-08-0-05, size 25
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) according to EN 175301-803

Application

The valve works in power units running mineral oil of group HL, as usual in presses and forming machines. With a different hydraulic fluid the seal material has to be checked. A flow of 700 l/min serves cylinders with a large piston diameter.
