The size can be customized and stainless steel is avaliable.■The body coat with hard anodized, polyester PTFE or nicke.■The two independent external travel bolts can accurately agjust ±5°at both open and close position.1.IndicatorMulti-function position indicator with Namur is convenient for mounting accessories such as positioner, limit switch and so on.2.PinionThe pinion is high-precision and integrative, made from nickle plating steel, full conform to the standards of ISO5211, DIN3337, NAMUR Standard. The size can be customized and stainless steel is available.3.Actuator BodyAccording to the different requirements, the extruded aluminum alloy STM6005 body can be coated with hard anodized, polyester PTFE or nickel.4.End capEnd caps are made of aluminum material, and can be coated with polyester, metal powder, PTFE and nickel.5.PistonThe twin rack pistons are made of aluminum die-casting coated with hard anodized or steel coated with Zinc. Long lifespan, fast operation and reversed rotation by simple reversing.6.Stroke AdjustmentThe two independent external travel bolts can accurately adjust ±5°at both open and close position.7.High Performance SpringPreloaded springs are made from high quality material for resistant to corrosion and longer lifespan, which can be demounted safely and conveniently to satisfy different requirements of torque by changing quantity of spring.8.Bearing & GuideMade from low friction, long-life compound material, to avoid the direct contact between metals. The maintenance and replacement are easy and convenient.9.O-ringsNBR O-rings provide trouble-free operation at standard temperature ranges. Viton or Silicone for high and low temperature.1.Work MediumDry or lubricated air or non-corrosive air. Dust below 30 micron.2.Air Supply PressureMin.Air pressure is 2 bar. Max.air pressure is 8 bar.3.Operating TemperatureStandard: -20 to +80℃Low: -40 to +80℃High: -20 to +120℃4.Stroke Adjustment±5°adjustment range at 0°and 90°point for rotation. Operating PrincipleAir from port A forces the points outwards, causes the pinion to turn counter-clockwise while the air exhausted through port B.Air from port B forces the pistons inwards, causes the pinion to turn clockwise while air exhausted through port A.Single ActingAir from port A forces the pistons outwards, and causes the springs to compressed, the pinion turns anticlockwise while air exhausted through port B.Then loss of air force, compressed spring force the piston inwards, causes the pinion turns clockwise.The non-standard rotation direction is to reverse the position of two pistons, the introduction of pressure into the A can rotate clockwise, the introduction of pressure into the B can rotate counterclockwise. Applied on small/middle rotary valves, such as ball valve, butterfly valve and so on.
