Directional Spool Valve Z4WEH10E51-4X/6EG24N9ETK4/B10V - Bosch Rexroth R901389325

Built as a sandwich plate, this pilot-operated directional spool valve sits between the subplate and the valve mounted on top and switches the direction of oil flow according to spool symbol E51. Pilot oil supply and return run internally, maximum operating pressure is 315 bar and maximum flow is 160 l/min.

Benefits

• Sandwich plate design - the valve takes no extra footprint on the manifold and follows the size 10 port pattern ISO 4401-05-04-0-05.
• Internal pilot oil routing - supply and return use the main circuit, so no extra lines are required.
• Concealed auxiliary actuation - the switching position can be checked if the electrics fail, without being triggered by accident during operation.
• Maximum operating pressure 315 bar with 2 switching positions and 4 ports.
• FKM seals for HL hydraulic fluid.
• 4.46 kg weight and solenoid actuation on 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.

Technical data

Applications

The sandwich plate format is chosen when an existing valve stack needs an extra switching function without redrilling the manifold. Typical tasks are shut-off and reversing duties on press and injection moulding axes at 160 l/min. Because pilot oil is routed internally, sufficient pressure must be present in the main circuit while the valve switches.
