Directional Spool Valve 4WEH 16 G7X/6EG12N9K4/P4,5 - Bosch Rexroth R978030481

Not every machine provides 24 V. This pilot-operated directional spool valve of size 16 switches on 12 VDC, carries up to 300 l/min across 4 ports in 3 switching positions and works up to a maximum operating pressure of 280 bar.

Benefits

• 12 VDC solenoid actuation - suits controls and on-board supplies without a 24 V level.
• External pilot oil routing - pilot supply and return sit outside the valve, so the pilot pressure can be set separately.
• 300 l/min maximum flow - pilot operation carries the switching forces that arise at this throughput.
• 280 bar maximum operating pressure - matched to power units in the upper pressure range.
• Spool symbol G with 3 switching positions - the centre position is defined by it.
• 8.9 kg weight - subplate mounting to ISO 4401-07-07-0-05.

Applications

The valve fits machines with a 12 V control supply, for example mobile power units and special purpose machines with their own on-board electrics. External pilot oil routing allows a separate pilot pressure supply when the main circuit is run without pressure at times. Installation is on a subplate to ISO 4401-07-07-0-05 and the intended hydraulic fluid is HL.
