Pneumatic valve actuator description: 14 types ( da 32- da 270 ). Offering a broad range of pneumatic rack & pinion actuators. The ports are namur standard for easy solenoid valve connection. Iso 5211 dimensions on all sizes. All internal and external surfaces are anodized for corrosion resistance. Actuator have a regulation range from-4° to +4°. Shaft bearings isolate the pinion gear from the housing and support the shaft for high cycle. Actuator can be lifted on many styles of quarter-turn valve, including ball, butterfly and plug and dampers. Pneumatic valve actuator operation: Working pressure: 2.5 bar – 8 bar. Working temputure: Standard range: -20? - +80?. Low temperature range: -40? - +80?(hnbr). High temperature range: -20? - +150?(vition). Factory lubricated for life under normal vorking. Operating media – dry or lubricated air, non-corrosive and inert gas or light hydraulic oil. Angle of rotation: 0° to -90°± 4°.
