DHZE-A, DKZE-A
Open-loop direct operated proportional
directionalvalves with threaded type
proportional solenoids, certified
according to North American standard
cURus.
They operate in association with electronic
drivers, see section
, 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 and .
Size: 06 and 10
Max flow: up to 70 and 160 l/min
Max pressure: 350 bar (DHZE)
315 bar (DKZE)

Notes: above performance data refer to valves coupled with Atos electronic drivers, see section .
the flow regulated by the directional proportional valves is not pressure compensated, thus it is affected by the load variations.To keep costant the
regulated flow under different load conditions, modular pressure compensators are available (see tab. D150).
(1) For different
D
p, the max flow is in accordance to the diagrams in sections 7.2 and 8.2
(2) 0-100% step signal
DHZE and DKZE proportional valves are CE marked according to the applicable
Directives (e.g. Immunity/Emission EMC Directive and Low Voltage Directive).
Installation, wirings and start-up procedures must be performed according to
the general prescriptions shown in table F003 and in the installation notes sup-
plied with relevant components.
