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.

NOTE: Having a counterpressure on the outlet connection of at least 25% of the inlet pressure ensures the good functioning of the valve and improves its
performance. Example: with inlet Pressure = 1 bar on the outlet connection, a min. counterpressure of 250 mbar is recommended.
