Flow control valves type QV-06
pressure compensated, two way, ISO 4401 size 06
T

C210-7/E
Q
V are flow control valves with pressure
c
ompensator 햲: the controlled flow rate is
i
ndependent of pressure variations.
T
hey are usually supplied with a built-in
check valve 햳 to allow the free flow in the
opposite direction.
The flow is regulated by turning a gradua-
t
e micrometer knob 햴. Clockwise rotation
increases the flow regulation.
O
ptional versions with locking key 햵 on
the adjustment knob are available on
r
equest.
ISO 4401 size 06.
Flow up to 1,5; 6; 11; 16; 24 l/min (depen-
ding on models).
P
ressure up to 250 bar.
V
alves designed to operate in hydraulic
s
ystems with hydraulic mineral oil or
synthetic fluid having similar lubricating
c
haracteristics.

The modular plates type BHQ allow the assembling of valves type QV-06 in a modular stack with other components having ISO 4401 size 06
mounting surface. See below for model code and functional sketches; see section for dimensions and example of assembly.
Available also version for phosphate ester (add /PE at the end of the model code).
The plates type BHQ are supplied with 4 fastening bolts M5x60 (8 for BHQ-012 and BHQ-022) to fix one (or two) QV-06 which are supplied
without fastening bolts.
