Directional Spool Valve 4WEH16J7X/6EG24N9ETSK4/10B10 - Bosch Rexroth R900720784

Without external pilot lines, assembly shrinks to the four main ports, since the pilot stage takes and drains its oil inside the valve. The spool with symbol J works in three switching positions. Up to 300 l/min passes across the ISO 4401-07-07-0-05 subplate at a maximum of 280 bar.

Benefits

• Internal pilot oil supply and internal pilot oil return, no pilot lines to the outside
• Spool symbol J, three switching positions, four ports
• Up to 300 l/min in size 16 at a maximum of 280 bar
• Subplate mounting to ISO 4401-07-07-0-05
• 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803
• Mass 11.25 kg, NBR seals for HL fluid

Application

On standard power units whose main circuit stays pressurised, the internal pilot path is the simplest route. It saves two lines per valve, along with fittings, hoses and potential leak points. Circuits that idle without pressure at times call for an externally fed build instead.

Manufacturer

Bosch Rexroth lists this pilot-operated directional valve 4WEH16J7X/6EG24N9ETSK4/10B10 under material number R900720784. Data sheets RE 24751 and RE 07600-B carry the characteristic curves, the installation dimensions and the interface data. The internal pilot path assumes that pilot pressure is permanently present at port P.
