SERIES AP DIRECTLY OPERATED PROPORTIONAL VALVES 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. 2/2-way proportional valves, NC Sizes: 16 - 22 mm PWM or current operation Open loop flow control Suitable for use with oxygen Several versions available: With body in PVDF (size 16mm only) With rear flanged bodies With lower flanged bodies Also suitable for use with vacuum Seals in FKM and NBR

General data Function proportional directly operated M5 - G1/8 - with rear flanges - with lower flanges Operating temperature filtered compressed air, unlubricated, according to ISO 8573-1 class 3.4.3, inert gas. All the valves are suitable for use with oxygen. body = brass / PVDF (for size 16mm only) seals = NBR and FKM GP7 193 ohm 125 mA Nominal resistance Rated current 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,...
