Directional Spool Valve 4WEH16HW7X/6EG24N9K4 - Bosch Rexroth R901253508

The larger the flow, the larger the forces acting on the spool. The directional spool valve 4WEH16HW7X/6EG24N9K4 answers that with a hydraulic pilot stage and therefore still switches three positions to symbol W at 300 l/min.

Advantages

• Three switching positions to symbol W at a flow of up to 300 l/min, made possible by the hydraulic pilot stage.
• Size 16 to ISO 4401-07-07-0-05, four ports for cylinders and hydraulic motors with a high oil demand.
• Maximum operating pressure 280 bar, with the frame staying at 10.1 kg.
• External pilot oil supply and external pilot oil return, the pilot circuit is fed and relieved independently of the main circuit.
• Solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) according to EN 175301-803.
• NBR seals for HL hydraulic fluid.

Application

The valve controls main axes in presses, lifting gear and large power units where a drive needs a third defined state besides extending and retracting. Size 16 releases the oil flow for fast strokes on large cylinders. The separate pilot circuit makes it possible to keep the pilot pressure steady regardless of a fluctuating pressure in the main circuit. Mounting is on a subplate or in a control block to ISO 4401-07-07-0-05.
