Series AP
directly operated proportional valves
2/2-way proportional valves, NC
Sizes: 16 - 22 mm
Series AP directly operated 2/2-way
proportional solenoid valves, NC, with
nominal diameters range from 0.8 to
2.4 mm, can be used where an open
loop flow control is required, with gas
mixtures, to control free flows or blows,
or emptying chambers using vacuum.
Series AP proportional valves have been
manufactured to optimize and reduce
friction and stick-slip effects.
The output flow is proportional to the
control signal.
As they can work also in vacuum,
a minimum working pressure is not
required.

While choosing the valve characteristics and in order to reach the highest performances, it is important to know that there must be a pressure difference of
90% at least between the inlet and the outlet. For example: inlet P 10 bar - outlet P max 1 bar up to free flow.
