Directional Spool Valve 4WEH16M7X/6EG24N9K4K - Bosch Rexroth R900705891

The spool decides which of the four ports are joined in each of the three positions. The pilot-operated directional spool valve 4WEH16M7X/6EG24N9K4K is built to symbol M and carries up to 300 l/min at a maximum of 280 bar.

Benefits

• Three switching positions to symbol M across four ports in size 16.
• 300 l/min rated flow on port pattern ISO 4401-07-07-0-05.
• External pilot oil supply and external pilot oil return, routed apart from the working circuit.
• Maximum operating pressure 280 bar with NBR seals for HL hydraulic fluid.
• 9.74 kg, solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803.

Applications

Anyone repairing an existing manifold needs exactly the symbol variant shown on the circuit diagram, because a different version changes how the axis behaves when de-energised. Symbol M is unambiguously identified by the type code, so the valve can be exchanged without further enquiry. The mounting face to ISO 4401-07-07-0-05 stays unchanged.
