Directional Spool Valve 4WEH16L7X/6EG24N9EK4/B15 - Bosch Rexroth R901355639

A separate return keeps the pilot pressure clear of fluctuations in the tank line. This valve uses an external pilot oil return for that, while the supply comes internally from the working circuit, at up to 300 l/min.

Benefits

• Internal pilot oil supply, so no dedicated line is needed to feed the pilot stage.
• External pilot oil return, so pressure surges in the tank line do not act back on the pilot stage.
• Three switching positions to symbol L at 300 l/min and up to 280 bar.
• Port pattern ISO 4401-07-07-0-05, subplate mounting straight into the manifold with no piping of its own.
• 9.74 kg, solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803, NBR seals for HL hydraulic fluid.

Applications

This split is common where several valves share one tank line and switching peaks build up there. In size 16 it moves large cylinders on presses, punching machines and lifting gear. The valve weighs 9.74 kg and is driven by a solenoid at 24 VDC.
