Proportional flow valves type QVHZO, QVKZOR
pressure compensated, direct operated, two or three way, ISO/Cetop size 03, 05
QVHZO and QVKZOR are proportional
valves, direct operated, which provide
compensated flow control according to
the electronic reference signals.
connector
They operate in association with electronic drivers, see table , which supply the proportional valves with correct
current signal to align valve regulation
to the reference signal supplied to the
electronic driver (which may be integral
or Eurocard type).

metallic or plastic,
see section dotted line:

These valves have a throttle ➀ directly
operated by ZO(R) solenoids ➁ and a
mechanical pressure compensator ➂
which compensates pressure variation
to keep a constant ∆p across the throttle.

NOTES TO TABLES AND 4
(1) Typical characteristics in table refer to valves coupled with Atos electronic drivers and operation with ISO VG-36 mineral oil at 50°C.
(2) Values are referred to 3-way configuration. In the 2-way configuration, the values of min regulated flow are higher.
(3) Reponse times at step signal (0%→100%) are measured from 10% to 90% of step value and are strictly referred to valve regulation.
