Directional Spool Valve H-4WEH25HJ6X/6EG24N9K4 - Bosch Rexroth R901295255

Feeding and returning the pilot oil externally keeps the tank line of the main circuit clear. The H-4WEH25HJ6X/6EG24N9K4 is built that way and switches up to 700 l/min to spool symbol J.

Benefits

• External pilot oil supply and external return, independent of counter pressure in the tank line.
• Spool symbol J with 3 switching positions across 4 ports.
• 700 l/min at a maximum of 350 bar in size 25.
• Subplate mounting to ISO 4401-08-08-0-05, NBR seals for HL hydraulic fluid.
• 19.14 kg, 24 VDC, 3-pole connector (2 + PE) to EN 175301-803.

Application

It suits plants that provide a separate pilot supply, such as large forming presses or clamping systems. The external return keeps the pilot stage clear of pressure swings in the return line. The spool design handles frequent reversals under load.
