Directional Spool Valve 4WEH16G7X/6EG24N9EK4/B10 - Bosch Rexroth R901198752

The valve covers three switching positions to symbol G and is shifted hydraulically by a pilot stage. Pilot oil comes from the working circuit while its return leaves through a line of its own, at up to 300 l/min.

Benefits

• Symbol G with three positions across four ports.
• Internal supply, external return, so only the pilot return has to be routed in the manifold.
• 300 l/min at up to 280 bar in size 16.
• Port pattern ISO 4401-07-07-0-05, so the valve fits any subplate of this size.
• Wired through a 3-pole connector (2 + PE) to EN 175301-803 at 24 VDC, sealed with NBR for HL hydraulic fluid, 9.82 kg.

Applications

This design moves large cylinders in presses, lifting gear and punching machines. Because pilot oil comes from the working circuit, that pressure has to reach the minimum pilot pressure, including at the end of the cycle. The separate return makes sure switching peaks in the tank line do not reach the pilot stage.
