Series A Stainless Steel Actuator<\/h3>\n\n\n\n

Material & Surface Treatment<\/strong><\/p>\n\n\n\n

First, Series A uses 303, 304, 316 and 316L stainless steel raw material.Besides, makers polish outer surfaces via electrolytic finishing craft.
Thus, the body looks smooth and gains outstanding anti-corrosion ability.Furthermore, it fits projects with strict anti-rust and anti-corrosion demands.<\/p>\n\n\n\n

Internal Structural Design<\/strong><\/p>\n\n\n\n

Primarily, it follows double piston rack-and-pinion inner layout.Therefore, the whole body stays compact with symmetric mounting spots.
Also, users switch output shaft rotation direction with easy steps.Meanwhile, this layout brings fast movement and extended service life.<\/p>\n\n\n\n

Wear Reduction Accessories<\/strong><\/p>\n\n\n\n

First, composite bearings and guide rings sit behind rack sections.Hence, moving parts slide smoothly with low friction resistance.
Besides, these fittings raise running precision for every operation.Furthermore, such setup effectively lengthens the actuator\u2019s lifespan.<\/p>\n\n\n\n

Spring & Gear Configuration<\/strong><\/p>\n\n\n\n

Primarily, pre-coated combined springs fight rust and last for long time.Meanwhile, high-precision racks and gears keep tiny meshing gaps.
Also, tight matching helps the unit deliver stable and strong output power.Besides, all fasteners adopt stainless steel for corrosion prevention.<\/p>\n\n\n\n

Standard Mount Dimensions<\/strong><\/p>\n\n\n\n

First, key slots and thread holes follow global NAMUR specification.Also, top mounting holes and air ports comply with NAMUR rules.
In addition, bottom holes match ISO5211 and DIN3337 standards.Therefore, workers mount solenoid and limit switches with great ease.<\/p>\n\n\n\n

Working Principle: Double-Acting Actuator<\/strong><\/p>\n\n\n\n

First, compressed air enters two separate air chambers in turns.Then, air pushes dual pistons to drive racks for straight movement.
Next, racks turn pinion and output shaft to open or link matched valves.Besides, opposite air intake reverses rotation to finish valve closing.<\/p>\n\n\n\n

Technical Operating Conditions<\/h3>\n\n\n\n
    \n
  1. Working Medium<\/strong><\/li>\n<\/ol>\n\n\n\n

    First, this actuator runs on clean compressed air for daily operation.Besides, non-corrosive gas and light oil also work as available media.
    Thus, users pick proper gas based on their on-site pipeline conditions.<\/p>\n\n\n\n

      \n
    1. Operating Pressure Range<\/strong><\/li>\n<\/ol>\n\n\n\n

      First, double-acting units take air pressure from 2 bar up to 8 bar.Meanwhile, single-acting versions share this same 2~8 bar working range.
      Furthermore, stay inside this scope to keep steady actuator performance.<\/p>\n\n\n\n

        \n
      1. Working Ambient Temperature<\/strong><\/li>\n<\/ol>\n\n\n\n

        First, standard NBR seals support temperature from -20\u2103 to +80\u2103.Besides, low-temperature NBR fits environments of -35\u2103 to +80\u2103.
        Also, viton rubber works between -15\u2103 and +150\u2103 for high heat spots.<\/p>\n\n\n\n

          \n
        1. Stroke Adjustment<\/strong><\/li>\n<\/ol>\n\n\n\n

          First, piston ends carry around \u00b14 degrees of adjustable travel space.Therefore, workers fine-tune opening range during valve assembly work.
          Besides, small adjustment fixes minor matching gaps with connected valves.<\/p>\n\n\n\n

            \n
          1. Lubrication Requirement<\/strong><\/li>\n<\/ol>\n\n\n\n

            First, regular running needs no extra grease under normal conditions.Thus, maintenance teams cut routine oil adding steps for field equipment.
            Furthermore, pre-filled internal grease lasts through long service cycles.<\/p>\n\n\n\n

              \n
            1. Installation Environment<\/strong><\/li>\n<\/ol>\n\n\n\n

              First, the actuator suits both indoor and outdoor mounting positions.Besides, common outdoor weather will not damage its standard structure.
              Hence, engineers arrange installation flexibly across various projects.<\/p>\n\n\n\n

                \n
              1. Maximum Inlet Pressure<\/strong><\/li>\n<\/ol>\n\n\n\n

                First, input air pressure never goes over the limit of 10 bar.Besides, overpressure will hurt inner seals and shorten total service life.
                Therefore, install pressure regulators to control incoming air value.<\/p>\n\n\n\n
