Pressure compensating, direct operated proportional flow control valves without position transducer for open-loop flow regulation.

A - for coupling with an off-board driver
AEB - basic execution's, integral, digital, electronic driver, analog reference signals; a USB port for software and functional parameters' setting
AES - with a fully integrated, digital, electronic driver and Fieldbus interface for functional parameters' setting, reference signals, and real-time diagnostics

Pressure compensating direct operated proportional flow control valves with an LVDT position transducer, for the best accuracy of flow regulation. The valve operates in association with digital off-board drivers. The mechanical pressure compensator keeps a constant Δp across the proportional throttle, thus, the regulated flow is independent of the load conditions. 

Depending on the installation requirements, the valve is applicable in a 2-way or 3-way connection. The 3-way connection option the exceeding flow from A to B ports, not regulated returns to the tank through the P port.
