Directional Spool Valve 4WEH16HD7X/6EG24N9S2K4 - Bosch Rexroth R900946162

Large lifting cylinders need a lot of oil in a short time, and every restriction on the way costs force. The pilot-operated 4WEH16HD7X directional spool valve in size 16 passes up to 300 l/min and reverses the direction of travel at operating pressures up to 280 bar.

Advantages

• Up to 300 l/min of flow in size 16, matched to cylinders with a large swept volume.
• Two switching positions to symbol D, so the control moves between two clearly defined states.
• Maximum operating pressure 280 bar across the four ports of the main circuit.
• External pilot oil supply and external pilot oil return keep the pilot stage operable under changing load pressure.
• Connection diagram ISO 4401-07-07-0-05 as a subplate mounting, weight 10.3 kg.
• Solenoid actuation at 24 VDC, wired through a connector, 3-pole (2 + PE) according to EN 175301-803.

Application

The valve controls cylinders and hydraulic motors in presses, forging lines and heavy lifting gear where 300 l/min has to be moved. Two switching positions to symbol D suit sequences that alternate between two states without needing a third position. Mounted on a subplate to ISO 4401-07-07-0-05, the valve sits directly on the manifold block and long pipe runs are avoided.
