Gas valve Series AP

proportionalPVDF

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. 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 Working 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. Installation - any position Materials - body = brass / PVDF (size 16mm only) seals = NBR, FKM, EPDM Nominal resistance - GP7 GPH U711 U712 193 ohm 48 ohm 85 ohm 22 ohm Rated current - 125 mA 250 mA 271 mA 542 mA
