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.

PWM or current operation

Open loop flow control

Also suitable for

use with vacuum

Several versions available:

with body in PVDF

(size 16mm only),

with rear flanged bodies

with lower flanged bodies,

suitable for use with oxygen

Seals in FKM and NBR

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.
