Directional Spool Valve 4WEH16HK7X/OF6EG24N9K4 - Bosch Rexroth R900935966

On the 4WEH16HK7X/OF6EG24N9K4 both supply and return of the pilot oil lie outside the valve. The pilot circuit can therefore be laid out independently. In the main circuit 300 l/min at 280 bar are available, switched by symbol K in two positions.

Benefits

• Pilot oil fed and discharged externally, version OF6EG24N9K4
• Symbol K with two switching positions and four ports
• 300 l/min nominal throughput at up to 280 bar operating pressure
• Size 16 on a subplate to ISO 4401-07-07-0-05
• 24 V DC solenoid with a 3-pole connector (2 + PE) to EN 175301-803
• NBR seals for HL, weight 9.78 kg

Application

In plants with a dedicated pilot pump the pilot pressure stays constant even when the main circuit collapses. The externally routed return keeps the pilot stage clear of back pressure in the collecting line. Together this makes the switching behaviour at 300 l/min predictable.

Manufacturer

Bosch Rexroth, material number R900935966. Permitted pilot pressure and the limits of the pilot stage are given in data sheet RE 24751, further reading in RE 07600-B.
