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°.

Pneumatic actuators are devices that convert the energy of compressed air or gas into a mechanical motion that regulates one or more final control elements. Designation Value Maximum operating pressure 16 bar Maximum operating temperature (�°C) 120�°C Cylinder starts operating pressure 1 bar Cylinder completely opening pressure 3 bar Bore 60 mm Strokes 40 mm Operating load 630 N Precompression load 300 N

Full conformance to the latest specification:iso5211, din3337, vd/vde3845and namur. The extruding high intensity aluminum body possess a honed internal surface coated with hone anode oxygenation for long life, low coefficient of friction and swift performance. Excellent, compact and modernized construction along with multi-specifications make the selection both economic and beneficial. All acting surfaces adopt high quality bearings, resulting in low friction, high cycle life and no noise. The two independent external travel stop adjustment bolts can easily and precisely adjust both open and close directions. Same outline actuator have the functional modes of double acting and spring, and the spring return has the normal-open and normal-close styles. Multi-function position indicator with numer is convenient for mounting accessories. Pre-compressed load spring is convenient for safe mounting and teardown procedures. Die-casting aluminum pistons and end caps have high intensity and light weight. Different o-rings materials are available for high and low temperature. According to different demands we can offer multi-travel rotations (e.G. ) and three Position actuators. Solenoid valves are easily mounted without any connecting plank.
