Directional Spool Valve H-4WEH25HE6X/6EG220N9SK4 - Bosch Rexroth R901070411

Where control voltage comes from a 220 V DC network, valves with a 24 VDC solenoid are out. The pilot-operated H-4WEH25HE6X/6EG220N9SK4 directional spool valve is wound for 220 VDC, switches flows up to 700 l/min, released to 350 bar operating pressure.

Benefits

• Solenoid voltage 220 VDC, matching plants with a DC network instead of 24 VDC control
• Maximum flow 700 l/min in size 25, connection diagram ISO 4401-08-08-0-05
• Maximum operating pressure 350 bar, 3 switching positions, 4 ports
• Spool symbol E, external pilot oil supply, external pilot oil return
• 3-pole connector (2 + PE) to EN 175301-803, UKCA conformity under the Low-Voltage Directive SI2016/1091
• NBR seals for HL hydraulic fluid, weight 20.33 kg

Application

The valve goes into steelworks, presses as well as special machinery whose control system runs on 220 V DC. External pilot routing keeps it working even when the cycle drops working pressure below pilot pressure. At 700 l/min it covers large cylinder axes as well as motor axes.
