Rexroth Proportional Valve 4WRAE Equivalent / Replacement ,RT4WRAE

RT4WRAE, the 4/2 and 4/3 proportional directional valves, are designed as direct operated devices in plate design. Operation by means of proportional solenoids with central thread and detachable coil. The solenoids are controlled via integrated electronics.These valves are used for analog control, a control method between ordinary switch control and servo control, and are particularly suitable for equipment innovation or renovation, which can greatly improve the automation control level of the equipment.

Features

– Direct operated proportional directional valve without electrical position feedback and integrated electronics (OBE) for type RT4WRAE.
– Control the direction and magnitude of a flow.
– Actuation by means of proportional solenoids with central thread and removable coil.
– For subplate mounting:
– Spring centred control spool.
– Control electronics: integrated electronics (OBE) with voltage input or current input;
– digital or analogue amplifier in Eurocard format (separate order); analogue module amplifier.
The advantages of the Rexroth 4WRAE proportional directional valve are mainly manifested in the followings:
– Compact structure, easy installation, and space saving.
– High control accuracy enables precise hydraulic control.
– Fast response speed, able to quickly respond to changes in control signals.
– Equipped with proportional control function, it can continuously control the action of hydraulic actuators based on the size and direction of input signals.
