Directional Spool Valve 4WEH16L7X/6EG24N9ETK4/12B10 - Bosch Rexroth R901305826

A cylinder passing a large flow can no longer be switched cleanly by a direct operated spool, solenoid force alone falls short. The pilot-operated directional spool valve 4WEH16L7X/6EG24N9ETK4/12B10 in size 16 carries up to 300 l/min at a maximum of 280 bar and takes its pilot oil internally.

Benefits

• Up to 300 l/min at a maximum of 280 bar, size 16 with an ISO 4401-07-07-0-05 hole pattern.
• Internal pilot oil supply and internal pilot oil return, so no extra pilot lines are needed in a manifold.
• Three switching positions to spool symbol L across four ports.
• Solenoid actuation at 24 VDC and a 3-pole connector (2 + PE) to EN 175301-803.
• NBR seals for HL hydraulic fluid at 10.02 kg.

Technical data

Application

The valve mounts on a subplate to ISO 4401-07-07-0-05 and controls cylinders and hydraulic motors in presses, injection moulding machines and power units. Internal pilot supply and return remove two pipe runs from a manifold. Wiring goes through a connector to EN 175301-803.

Manufacturer

Bosch Rexroth lists this pilot-operated directional valve 4WEH16L7X/6EG24N9ETK4/12B10 under material number R901305826. Data sheets RE 24751 and RE 07600-B show characteristic curves, installation dimensions and the connection diagram. Spool symbol L, internal pilot routing and connector wiring fix where this valve belongs in a control manifold.
