Directional Spool Valve 4WEH16U7X/6EG24N9K4 - Bosch Rexroth R900928505

Above roughly 100 l/min the force of a direct operated solenoid is no longer enough. The 4WEH16U7X/6EG24N9K4 solves this with a pilot stage and so sustains 280 bar operating pressure at a nominal throughput of 300 l/min. Symbol U does the switching.

Benefits

• Operating pressure up to 280 bar at a nominal throughput of 300 l/min
• Symbol U with three switching positions across four ports
• Pilot-operated, pilot oil routed externally in supply and return
• Size 16 on a subplate to ISO 4401-07-07-0-05
• 24 V DC solenoid, 3-pole connector (2 + PE) to EN 175301-803
• NBR seals, HL hydraulic fluid, weight 9.84 kg

Technical data

Application

The version is used in power units whose working pressure reaches close to 280 bar. The pilot stage delivers the spool forces reliably even at full throughput. The external control circuit stays clear of the pressure surges in the main circuit.

Manufacturer

Bosch Rexroth, material number R900928505. The limits for pilot pressure and throughput are listed in data sheet RE 24751, supplemented by RE 07600-B.
