Directional Spool Valve 4WEH16H7X/6EG24N9ETK4/B10 - Bosch Rexroth R901045618

External pilot lines take up room on the manifold and add another sealing point. The pilot-operated directional spool valve 4WEH16H7X/6EG24N9ETK4/B10 routes both pilot oil supply and pilot oil return internally while passing up to 300 l/min at a maximum of 280 bar.

Benefits

• 300 l/min in size 16 at a maximum operating pressure of 280 bar.
• Internal pilot oil supply and internal pilot oil return, so the manifold needs no separate pilot bores.
• Three switching positions to spool symbol H across four ports.
• Solenoid actuation at 24 VDC, wired through a connector, 3-pole (2 + PE) according to EN 175301-803.
• 9,73 kg, subplate mounting to ISO 4401-07-07-0-05, NBR seals for HL hydraulic fluid.

Application

The valve controls cylinders and hydraulic motors in presses, injection moulding machines and test rigs whose main circuit stays pressurised. Because pilot oil comes from the valve own P port, no separate pilot source is required. The interface pattern to ISO 4401-07-07-0-05 is defined across manufacturers.
