Directional Spool Valve H-4WEH25H6X/6EG24N9TS2K4 - Bosch Rexroth R901267209

The spool with symbol H sets how cylinder and pump stand relative to each other in the centre position, which makes it the decisive selection feature. The pilot-operated size 25 main stage passes up to 700 l/min at 350 bar operating pressure. Pilot oil comes from an external circuit while the return runs inside the valve.

Benefits

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

Application

The valve works on large cylinders in presses, lifting gear and test rigs. The external control circuit keeps switching time even under a fluctuating working pressure. Because the return runs inside the valve, control port X alone is enough at the subplate.

Manufacturer

Bosch Rexroth lists this directional valve H-4WEH25H6X/6EG24N9TS2K4 under material number R901267209. The data sheets Directional spool valves, pilot-operated (RE 24751) and Hydraulic valves and hydro- (RE 07600-B) carry the characteristic curves and installation dimensions. For this version the tank line of the main stage has to drain without pressure.
