Directional Spool Valve 4WEH16HC7X/OF6EG48N9ETK4/B10P4,5 - Bosch Rexroth R900753644

In the main circuit of large presses and power units the oil direction has to change reliably even at full delivery. The pilot-operated directional spool valve 4WEH16HC7X/OF6EG48N9ETK4/B10P4,5 handles that job for a maximum flow of 300 l/min at a maximum operating pressure of 280 bar. Pilot oil supply and pilot oil return are internal, and the main spool is moved by solenoid actuation at 48 VDC.

Benefits

• Pilot-operated design in size 16 for a maximum flow of 300 l/min.
• Maximum operating pressure of 280 bar, port pattern to ISO 4401-07-07-0-05 for subplate mounting.
• Two switching positions to spool symbol C across four ports.
• Solenoid actuation at 48 VDC, so it runs on a 48 V control system without an intermediate power supply.
• Internal pilot oil supply and internal pilot oil return, no extra pilot lines required.
• Weight of 9.72 kg, NBR seals for hydraulic fluid HL.

Applications

The valve belongs in the main circuit of presses, test rigs and power units where a cylinder or hydraulic motor is reversed at high flow. The 48 VDC version suits machines whose control cabinet already provides that voltage. It mounts on a subplate to ISO 4401-07-07-0-05, and the NBR seals are matched to hydraulic fluid HL.
