Directional Spool Valve 4WEH16G7X/6EG24N9TK4/B10 - Bosch Rexroth R901426705

This valve pairs an external pilot oil supply with an internal return. The pilot return therefore ends in the tank line of the manifold while the pilot pressure comes from a source of its own. Up to 300 l/min are switched across three positions.

Benefits

• External pilot oil supply, so pilot pressure survives a drop in working pressure.
• Internal pilot oil return, which saves an extra return line in the manifold.
• Three switching positions to symbol G at 300 l/min and up to 280 bar.
• Hole pattern ISO 4401-07-07-0-05 for size 16, subplate mounting with no extra fittings.
• NBR seals and HL hydraulic fluid, solenoid actuation at 24 VDC through a 3-pole connector (2 + PE) to EN 175301-803, 9.84 kg.

Technical data

Applications

Combinations like this appear in manifolds that already carry a filtered pilot supply but need to save space in the tank line. Typical plants are presses, lifting gear and clamping systems in size 16. The valve weighs 9.84 kg and is switched by a solenoid at 24 VDC.
