The 4/2 and 4/3 proportional valves are directly controlled components of subplate mounting design. They are actuated by proportional solenoids with an integrated linear feedback to assure accurate positioning related to a command signal. The valves are available with either external control electronics (model WRP) or by integrated valve electronics (model WRPE).


•Sizes 6 and 10
•For subplate mounting:
– Size 6: Porting pattern according to ISO 4401-3, NFPA T3.5.1M R1, and ANSI B 93.7 D 03
– Size 10: Porting pattern according to ISO 4401-5, NFPA T3.5.1M R1, and ANSI B93.7 D 05
•Control of the direction and magnitude of a flow
•Use for position, velocity and pressure control
•Actuation through control solenoid
•Position sensing of the control spool via an inductive position transducer
•Characteristic curves with and without inflection
•Spool and sleeve in servo-type quality
•Integral electronics (OBE) for type 4WRPEH
