Product Specs

The air units include air regulator, filter and lubricator. Air regulator makes the gas supply pressure stable and constant, so as to reduce damage on valve or actuator due to sudden change in gas supply pressure. Filter deans the gas supply, which can filter the moisture in condensed air, lubricator lubricates the moveable parts and parts that are difficult to lubricate. This greatly extends the lifecyde of machine.


1 .dean the adaptor and joints before installation. No debris is allowed to get in the gas circuit.
2.    Check whether the direction of gas is consistent with the arrow. And please check the thread of adaptor and joint.
3.    Fix the filter, regulator (filter regulator) and lubricator: match the convex of support and notch of machine. Fasten it with stator and screw.
4.    Fix the regulator and filter regulator respectively: Rotate the fixed collar to fasten attached special stator.


1.    Drain water by pressure or manual. In manual function, have to drain the water before the water level reaching bottom of filter element
2.    Pull up the rotation button before rotation, because the pressed rotation button is for positioning. Turn right to increase outlet pressure. Please adjust slowly and evenly to the requested pressure. You shouldn't adjust to the requested pressure by one step.
3.    Usage of lubricator: JISK2213 oil machine is adopted in the lubricator (ISO Vg 32 or equivalent oil). The oil cannot exceed 4/5 of the cup. Zero refers to the minimum oil and 9 refers to the maximum oil. You cannot rotate from 9 to 0, because it has to be rotated clockwise.


1 .Some components are made of PC materials, which cannot be used in or placed near by organic solvent. PC cup shall be washed in neutral cleaner.

2-Don't make the pressure exceed the scope.
3.Change the filter element in time when the gas at outlet decreases significantly.

Features and Benefits

  • Compact Design
    The Luobai rack & pinion pneumatic actuator produces linear torque output in a compact design utilizing the same body and end caps for double-acting and spring-return units.
  • Degree of Travel
    The standard angle of rotation is 90°. Luobai actuators feature dual travel stops that provide ± 10° stroke rotation on both the opening and closing phases of the actuator stroke. 110° of travel in a standard 90° actuator!
  • Honed Bore for High Cycle Life
    Extruded aluminum body is internally machined and honed to exact specifications. Honing prevents dry spots from forming within the actuator bore and therefore eliminates premature seal failure—a critical aspect to long cycle-life. All internal and external surfaces are hard anodized for corrosion resistance, with all units permanently lubricated at the factory.
  • High-Cycle Bearings
    Shaft bearings isolate the pinion gear from the housing and support the shaft for high-cycle applications. Many competitive manufacturers do not provide this critical feature.
  • High Cycle-Life Wear Pads
    Pistons incorporate double wear pads (skates) to separate the rack from the actuator wall and serve as both guide and wear bearings.
  • Rugged Tooth Design
    The pinion teeth are engaged the full length and stroke of the piston, and designed for the toughest flow conditions. The pinion height allows manual override without needing to remove the indicator.
  • Multiple Output Shafts
    The female pinion drive is standard with a double-square output drive, and optional with a double-D drive, keyed drive and designs to meet your specific requirements.
  • Namur Mounting
    Namur VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners.
  • High Visibility Beacon
    External open/close indicator as standard, available for all rotations.
  • Safe Preloaded Spring Cartridges
    Epoxy-coated special steel springs are pre-loaded with non- metallic materials. The stainless steel end-cap fasteners are extra-long to allow for spring relaxation. All parts are corrosion-resistant.
  • Alternate Operating Media
    Air pressure operation from 40 to 150 psi (2 to 10 Bar). Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator.
  • Stainless Steel Fasteners
    All external fasteners are corrosion-resistant stainless steel.
  • Optional Accessories
    Luobai offers a wide range of adapters for many different types of valves—including butterfly valves, ball valves and plug valves—as well as a variety of pneumatic and electric automation accessories suitable for diverse industrial environments.
  • Quality Assurance
    100% of all units are factory pressure and leak tested, and individually boxed for shipment.
  • Traceability
    All units are externally marked with a progressive traceable serial number.
  • Best Warranty In The Industry
    Luobai products are covered by our unlimited cycle-life warranty. Contact your local distributor or sales representative for more details.
