Directional Spool Valve 4WEH16HC7X/OF6EG24N9K4 - Bosch Rexroth R900930451

A spool releasing 300 l/min faces flow forces that a solenoid alone cannot overcome. On the 4WEH16HC7X/OF6EG24N9K4 a hydraulic pilot stage takes that over. Symbol C switches in two positions at up to 280 bar.

Benefits

• Hydraulic piloting for reliable switching at 300 l/min
• Symbol C with two switching positions across four ports
• Operating pressure up to 280 bar in size 16
• Pilot oil fed and discharged externally, version OF6EG24N9K4
• Porting pattern ISO 4401-07-07-0-05, weight 9.74 kg
• 24 V DC solenoid, NBR seals for HL hydraulic fluid

Application

In presses and test rigs high flow forces occur when switching under load. The pilot stage then holds the spool securely in the selected position. Because the pilot oil comes from outside, the pilot pressure stays stable through load changes.
