Directional Spool Valve 4WEH16G7X/6EG12N9ETK4/B10P4,5 - Bosch Rexroth R900978622

A cylinder with a large swept volume can only be reversed if the valve releases the full oil flow. This size 16 version passes up to 300 l/min at a maximum operating pressure of 280 bar and is pilot-operated by solenoids on 12 VDC. Spool symbol G sets out the three switching positions across four ports.

Benefits

• Up to 300 l/min through the ISO 4401-07-07-0-05 hole pattern of size 16
• Maximum operating pressure 280 bar with hydraulic fluid HL and NBR seals
• Three switching positions to symbol G across four ports
• Internal pilot oil supply and internal pilot oil return on the size 16 valve, no additional control lines needed
• Solenoid actuation on 12 VDC through a connector 3-pole (2 + PE) to EN 175301-803
• Subplate mounting on a standard mounting plate, weight 9.86 kg

Applications

The valve goes into presses, hydraulic power units and test rigs where a large cylinder changes direction. The 12 VDC supply suits controls that carry no 24 V level. Subplate mounting to ISO 4401-07-07-0-05 lets it sit directly on an existing control manifold.
