Directly operated proportional valves Series AP
2/2-way proportional valves, NC
Sizes: 16 – 22 mm
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.
