series AP

Proportional flow valve

• Available in two sizes: 16 and 22 mm
• PWM or current operation
• Open loop flow control
• Also vacuum operation

Technical specifications

Construction	Proportional directly operated
Pneumatic connections	Size 16: M5 (on request: rear flange; male hose adaptor Ø-6 only for PVDF version) Size 22: G1/8 (on request: lower flange)
Materials	Body: Nickel-plated brass (on request: PVDF size 16mm only) Seals: NBR
Mounting	in any position
Operating temperature	0 ÷ 60 °C
Fluid	filtered compressed air, unlubricated, according to ISO 8573-1 class 3.4.3, inert gas. All the valves are suitable for use with oxygen.
Hysteresis	Size 16mm: 12% FS Size 22mm: 10% FS
Repeatability	7% FS
Solenoid valve dimensions	Size 16 = 16x26 DIN EN 175301-803-C Size 22 = 22x22 DIN 43650 Form B
Symbol	AP01 = directly operated flow control

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.
