Directional Spool Valve 4WEH16J7X/6EG24N9K4/10 - Bosch Rexroth R900933333

A double-acting cylinder that has to stand still between two movements needs a third switching position with a defined spool symbol. The pilot-operated directional spool valve 4WEH16J7X/6EG24N9K4/10 in size 16 does this to symbol J and passes up to 300 l/min while doing so.

Advantages

• Flow of up to 300 l/min through the subplate mounting to connection diagram ISO 4401-07-07-0-05.
• Three switching positions to spool symbol J across four ports, laid out for driving a double-acting consumer.
• Maximum operating pressure of 280 bar with HL hydraulic fluid and NBR seals.
• External pilot oil supply and external pilot oil return, so the pilot circuit can be fed independently of the main circuit.
• Solenoid actuation at 24 VDC through a connector, 3-pole (2 + PE) according to EN 175301-803.
• Weight of 10.26 kg, with pilot stage and main stage forming one assembly.

Application

The valve controls cylinders and hydraulic motors in presses, injection moulding machines and stationary power units where flows of up to 300 l/min are switched. The subplate mounting fits control plates and manifolds with the ISO 4401-07-07-0-05 hole pattern. Because pilot oil is fed in and drained externally, the pilot stage stays supplied even when the main pressure fluctuates strongly. HL hydraulic fluid and NBR seals define operation on mineral oil.
