Directional Spool Valve H-4WEH25E6X/6EG24N9K4/11 - Bosch Rexroth R901051497

Symbol E brings the consumer to a stop in mid-position and links pump and tank the way the spool defines. This pilot-operated size 25 valve carries up to 700 l/min at an operating pressure of 350 bar maximum and is driven from 24 VDC.

Benefits

• Spool symbol E with 3 switching positions and 4 ports for the classic reversal with a defined mid-position
• External pilot oil supply and external pilot oil return, which keeps pilot circuit and working circuit fully separate
• Flow of up to 700 l/min in size 25
• Operating pressure of 350 bar maximum on HL hydraulic fluid
• Supply voltage 24 VDC with solenoid actuation and connector, 3-pole (2 + PE) according to EN 175301-803
• Subplate mounting to ISO 4401-08-08-0-05 at a mass of 18.15 kg with NBR seals
