DHZE-A and DKZE-A are open-loop direct operated proportional valves with threaded type proportional solenoids, providing both directional and noncompensated flow control.

They operate in association with electronic drivers, see section 2, which supply the proportional valves with proper current to align the valve regulation to the reference signal supplied to the electronic driver. The spools are available with linear L, progressive S or differential D flow characteristics.

The valve body is 3 chambers type for DHZE and 5 chambers type for DKZE. The solenoid coils are plastic encapsulated with insulation class H and they are available with different nominal resistances depending to the voltage supply (12 VDC or 24 VDC) and to the electronic driver type, see section 2 and 4.
