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 ,ݘwhich 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 V DC) and to the electronic driver
type, see section ݘand .ݚ
Mounting surface:
ISO 4401 sizes 06 and 10.
Max flow with valve differential pressure
Δp = 30 bar, see section ݙ
50 l/min for DHZE - 105 l/min for DKZE
Max pressure = 350 bar for DHZE
315 bar for DKZE
