4BRKE Series

Pilot-operated two-stage proportional directional valve with electrical position feedback of the main spool, used to control the size and direction of the liquid flow

Sub-plate mounting type connection structure, connection size conforms to ISO 4401 standard

Spring centred main spool

With integrated proportional amplifier

The pilot control is a single-stage proportional directional valve

The pilot valve is a threaded proportional solenoid, and the coil can be disassembled separately
