Directional Spool Valve H-4WEH25HD6X/OF6EG125N9K4 - Bosch Rexroth R900954846

When buying a replacement, the solenoid voltage is what has to match first. The H-4WEH25HD6X/OF6EG125N9K4 is the 125 VDC build of size 25, with external pilot supply, external drain and up to 700 l/min flow.

Benefits

• 125 VDC supply voltage through a 3-pole (2 + PE) plug to EN 175301-803.
• 700 l/min flow at 350 bar maximum operating pressure in size 25.
• Pilot oil fed in and drained externally, pilot pressure and relief run through their own lines.
• Spool symbol D, two switching positions, four ports on the ISO 4401-08-08-0-05 pattern.
• 18.31 kg weight, NBR seals for HL hydraulic fluid, UKCA conformity to SI2016/1091.

Applications

This voltage variant is found on older presses and steelworks equipment whose controls were laid out for 125 V direct current. The valve fits the existing size 25 subplate and takes over the pilot oil routing already in place. Before replacement, compare voltage, spool symbol and pilot oil variant.
