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.

| Function | 2/2 NC |
| Operation | proportional directly operated |
| Ports | M5 - G1/8 - with rear flanges - with lower flanges |
| Hysteresis | Size 16mm: 12% FS - Size 22mm: 10% FS |
| Repeatibility | Size 16mm: 7% FS - Size 22mm: 7% FS |
| Operating temperature | 0 ÷ 60°C |
| Medium | filtered compressed air, unlubricated, according to ISO 8573-1 class 3.4.3, inert gas. All the valves are suitable for use with oxygen. |
| Installation | any position |
| Materials | body = brass / PVDF (size 16mm only) seals = NBR, FKM, EPDM |
| Nominal resistance | GP7 = 193 ohm - GPH = 48 ohm - U711 = 85 ohm - U712 = 22 ohm |
| Rated current | GP7 = 125 mA - GPH = 250 mA - U711 = 271 mA - U712 = 542 mA |
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.
