Directional Spool Valve 4WEH16Q7X/6EG24NETS2K4/B08 - Bosch Rexroth R900738769

Without a centre position a cylinder is left in an undefined state after switch-off. This valve switches in 3 positions to spool symbol Q, carries up to 300 l/min and works at operating pressure up to 280 bar.

Benefits

• 3 switching positions to spool symbol Q across 4 ports.
• Flow up to 300 l/min in size 16, maximum operating pressure 280 bar.
• 10.82 kg weight with NBR seals for HL hydraulic fluid.
• Internal pilot oil supply with internal pilot oil return, pilot-operated.
• Subplate mounting to ISO 4401-07-07-0-05 for fitting on the standard interface.
• Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803.

Application

The valve is used on cylinders that must stand still between two strokes, for example on feed drives and lifting gear. The centre position determines how the actuator behaves when the solenoids are de-energised. At 300 l/min the pressure drop across the valve stays within the design range of size 16.
