Directional Spool Valve 4WEH10J4X/6EG24N9S2K4/B10 - Bosch Rexroth R901270926

A cylinder drawing 160 l/min can no longer be controlled cleanly by a direct operated valve. The pilot-operated 4WEH10J4X directional spool valve in size 10 shifts its main spool hydraulically and handles that flow at operating pressures up to 280 bar.

Advantages

• Up to 160 l/min at a maximum of 280 bar, sized for drives that take power continuously.
• Three switching positions to symbol J give the control a defined centre position between the two working directions.
• External pilot oil supply and external pilot oil return keep the pilot stage independent of the load pressure in the main circuit.
• Four ports and connection diagram ISO 4401-05-05-0-05, a hole pattern that fits standard size 10 mounting plates.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.
• NBR seals for HL hydraulic fluid, weight 8.34 kg.

Technical data

Application

The valve sets the direction of travel of cylinders and hydraulic motors in presses, injection moulding machines and steel plant equipment. Because pilot oil is fed in and returned externally, the pilot stage keeps working when main circuit pressure fluctuates or drops away in the centre position. The subplate mounting to ISO 4401-05-05-0-05 places the valve on an existing plate or inside a manifold block.
