When the main circuit does not hold enough pressure for the pilot stage, the pilot oil has to come from outside. That is what the 4WEH16E7X/6EG24N9S2K4/B12 is built for: external pilot oil supply and external return, 300 l/min in size 16, up to 280 bar, spool symbol E.

Total price
A pilot-operated valve needs pilot pressure even while the main circuit is being run without load. The 4WEH16E7X/6EG24N9S2K4/B12 therefore takes its pilot oil externally and drains it externally, at a flow of up to 300 l/min.
Benefits
- External pilot oil supply and external pilot oil return, independent of the pressure in the main circuit.
- 300 l/min flow in size 16 across 4 ports.
- Spool symbol E with 3 switching positions.
- 280 bar maximum operating pressure at a weight of 10.86 kg.
- 24 VDC solenoid actuation through a connector, 3-pole (2 + PE) according to EN 175301-803.
- Subplate mounting to ISO 4401-07-07-0-05, matching common control blocks.

Applications
External pilot oil routing pays off in systems whose operating pressure drops below the required pilot pressure at times, for example during circulation or pressure reduction. The pilot oil then comes from its own circuit and stays clear of the main flow. In size 16 the valve controls cylinders and hydraulic motors up to 300 l/min.
