Directional Spool Valve 4WEH16Z7X/6EG24N9SK4 - Bosch Rexroth R901333713

The pilot circuit of this valve sits entirely outside the working circuit: pilot oil supply and pilot oil return are both external, so the switching time does not depend on the pressure state in the main line. The 4WEH16Z7X/6EG24N9SK4 realises spool symbol Z in 2 switching positions and passes up to 300 l/min in size 16.

Benefits

• 2 switching positions on spool symbol Z across 4 ports
• External pilot oil supply and external pilot oil return for consistent switching times
• 300 l/min flow at 280 bar maximum operating pressure
• 24 VDC solenoid actuation through a connector, 3-pole (2 + PE) according to EN 175301-803
• 10.46 kg weight, NBR seals matched to HL hydraulic fluid
• Subplate mounting to connection diagram ISO 4401-07-07-0-05

Technical data

Application

Systems with a dedicated pilot pump use this build because pilot pressure and working pressure can be set separately. Switching behaviour stays predictable even when the main circuit runs unloaded for a while or back pressure builds up in the return line. Typical installations are presses, clamping systems and test rigs in size 16.
