Directional Spool Valve H-4WEH25HC6X/6EG48N9TSK4 - Bosch Rexroth R901090159

For control circuits running on 48 V direct current this pilot-operated size 25 directional valve switches up to 700 l/min. Spool symbol C provides two switching positions across four ports. The electrical connection is a 3-pole connector to EN 175301-803.

Benefits

• Coil voltage 48 VDC, so no extra power supply is needed in the cabinet
• Two switching positions to spool symbol C across four ports
• Flow up to 700 l/min at operating pressures up to 350 bar
• External pilot oil supply with internal pilot oil return
• Connection diagram ISO 4401-08-08-0-05, nominal size 25
• Weight 17.61 kg with NBR seals

Application

Where an axis only alternates between two positions, a 4/2 directional valve is enough and the control circuit stays simple. Size 25 covers pump outputs that smaller valves can no longer carry. HL class mineral oil is the intended fluid.
