Digital proportional valves without position transducers and positive spool overlap for the directional control in an open-loop, and not compensated flow regulations. Valves are equipped with threaded type proportional solenoids, certified according to North American standard cURus.

The valve is equipped with an off-board driver that supplies the proper current, to align the valve's regulation to the reference signal supplied to the driver.

Valve's spools are available in - linear L, progressive S, or differential D flow characteristics. The valve's body is a 3-chambers type (for DHZE), and 5-chambers type (for DKZE).

Direct operated digital proportional valves with a positive spool overlap, for an open-loop directional control and not compensated 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.

Direct operated proportional valve without a position transducer. The valve provides both directional and not compensated flow control, according to the electronic reference signal.

It is derived from the standard DHZO, but with a single solenoid and the 3-position progressive spool with zero-overlap in the intermediate configuration. This feature makes the valve suitable for cost-effective closed-loop position control.

A - without position transducer
AE - as -A plus integral electronics

Size: 06
Max flow: 28 l/min. at 30 bar.

Open-loop, pilot operated proportional directional valves with high-flow capacity and compact dimensions. These valves are an ideal solution for applications where space is limited, and for a short period, high-flow performance is required.

The spools are available with linear L flow characteristics. Available solenoid coils' voltage supply - 12 V_DC or 24 V_DC, with optional connections.
