Directional Spool Valve 4WEH16L7X/6EG24N9K4 - Bosch Rexroth R900927835

Cycle time depends directly on how much oil the directional valve lets through. The 4WEH16L7X/6EG24N9K4 releases up to 300 l/min and uses the four size 16 ports to do it. Symbol L switches at a maximum of 280 bar.

Benefits

• 300 l/min nominal throughput for short stroke times on large cylinders
• Four ports in size 16 to porting pattern ISO 4401-07-07-0-05
• Symbol L across three switching positions
• Operating pressure up to 280 bar, pilot-operated version
• Pilot oil fed and returned externally, 24 V DC solenoid
• 3-pole connector (2 + PE) to EN 175301-803, NBR for HL, 9.82 kg

Application

On press cylinders and lifting tables the throughput sets the speed of the rapid stroke. At 300 l/min the valve stays the smaller restriction in the circuit even with large piston areas. The external pilot circuit allows the pilot stage to be filtered on its own.
