Directional Spool Valve 4WEH16M7X/6EG24N9EK4/B10 - Bosch Rexroth R978914135

The pilot stage of this valve draws its oil from the working circuit, so no second supply is required. That lets the 4WEH16M7X/6EG24N9EK4/B10 switch up to 300 l/min in size 16 across three positions.

Benefits

• Three switching positions to symbol M with a defined centre position across four ports.
• Internal pilot oil supply, so the manifold needs no separate feed line for the pilot stage.
• 300 l/min at up to 280 bar, with external pilot oil return for a path clear of tank pressure.
• Port pattern ISO 4401-07-07-0-05, subplate mounting straight into the manifold with no piping of its own.
• 9.8 kg, solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803, NBR seals for HL hydraulic fluid.

Applications

In presses, lifting gear and injection moulding machines, size 16 valves move the large axes. The spool chosen decides how the axis behaves once the valve returns to centre. Internal supply simplifies the piping because only the pilot return needs a line of its own.
