Directional Spool Valve 4WEH16HD7X/6EG24N9K4/10 - Bosch Rexroth R900944181

Hydraulic pressure does the switching work in the main stage while the solenoid drives only the pilot valve. That makes 24 VDC sufficient to divert up to 300 l/min in size 16. Pilot oil is supplied externally and returned externally.

Benefits

• 300 l/min main flow from a 24 VDC command signal
• Two switching positions to symbol D across four ports
• External pilot oil supply and external pilot oil return
• ISO 4401-07-07-0-05 interface, operating pressure up to 280 bar
• 3-pole connector (2 + PE) to EN 175301-803 as electrical connection
• Subplate mounting, NBR seals for HL hydraulic fluid, weight 9.72 kg

Applications

The valve sits in power units where a large consumer has to be switched from the existing 24 V control system. Piloting decouples the electrical power from the hydraulic throughput. Subplate mounting lets it go into an existing control manifold.

Manufacturer
