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

Technical data

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.
