Directional Spool Valve 4WEH16HD7X/OF6EG110N9TSK4 - Bosch Rexroth R901118507

Not every system has a spare return line for pilot oil. The 4WEH16HD7X/OF6EG110N9TSK4 returns pilot oil internally and therefore needs only the external supply, at flows up to 300 l/min in size 16.

Benefits

• External pilot oil supply with internal pilot oil return, one line less in the manifold.
• Solenoid rated 110 V DC, connector 3-pole (2 + PE) to EN 175301-803.
• 2 switching positions to spool symbol D, 4 ports.
• Flow up to 300 l/min, operating pressure up to 280 bar.
• Mounting pattern ISO 4401-07-07-0-05, mass 10.76 kg.
• UKCA to Low-Voltage Directive SI2016/1091, NBR seals for HL hydraulic fluid.

Applications

The valve controls cylinders and hydraulic motors in machine tools, presses and test rigs whose cabinet carries 110 V direct voltage. Internal pilot oil return saves a dedicated Y line to tank. NBR seals are fitted for mineral oil of class HL.
