REXROTH

Direct operated proportional directional control valves, which control both the direction and volume of a fluid flow
Mounts on standard ISO 4401-3, NFPA T3.5.1MR1 D 03 and ANSI B 93.7 D 03 interface
Two piece solenoid design with removable coils
Integrated electronics available
The 4WRA(E)B6 type direct operated proportional valves are available with or without on-board electronics (OBE). Suitable for open loop applications, the WRA(E)B6 does not have integral feedback, however provides proportional flow output dependant on a commanded value. The WRA(E)B6 may also be used with a DC switching signal, if the application requires throttled shifting without full proportional control
