JIMAI Pneumatic Actuators
Pneumatic actuators are the workhorses of countless automation systems. Explore our extensive product line to find the best fit for your specific application.
Comparing with others, JIMAI has below advantages:
1.Shaft material: JIMAI adopts ASTM5140 material, more durable and more resilient.
2.Shaft process: Every step of the process, from cutting the raw materials to the final product, is completed in-house by Jimai, and completed with the assistance of a robotic arm.
3.Star connection of shaft: JIMAI adopts hot punch process, which will increase the shaft hardness, while others use cold pressed .
4.Piston process: Processed by JIMAI own with the assistance of robotic arm.
5.End cover assemble: Assembly with actuator by automated screw machines, capable of installing eight screws simultaneously, to minimize deviations between the actuator body and end cover resulting from manual assembly.

Pneumatic actuators are essential for controlling chemical processes. They precisely regulate valve positions in pipelines carrying corrosive or hazardous materials, ensuring accurate mixing, batching, and flow control. They are also used to operate diverter valves directing flow to different reactors or holding tanks.
Explore Chemical Application Solutions →In construction, pneumatic actuators are used for precise positioning of equipment. They can control mixing operations in cement plants, adjust the tilt of solar panels, and operate louvers or dampers in large-scale ventilation systems within buildings.
Explore Construction Application Solutions →Pneumatic actuators play a critical role in oil and gas extraction, refining, and transportation. They are used in valve control for pipelines, tanks, and processing equipment. They also control the position of nozzles during the filling of tankers, improving safety and efficiency.
Explore Petroleum Application Solutions →These actuators are used to control material flow in processing equipment, such as regulating the flow of molten metal in casting processes. They can also be used for the precise positioning of tools in metalworking applications.
Explore Metallurgy Application Solutions →Pneumatic actuators are crucial in power generation and distribution. They are used to operate valves in power plants, control the position of solar reflectors in concentrated solar power (CSP) systems, and manage the operation of circuit breakers and switches in substations.
Explore Electricity Application Solutions →Pneumatic actuators are used in food and beverage processing for precise control over various operations, such as dispensing ingredients, opening and closing valves in filling machines, and adjusting the position of conveyor belts. They can be used in precise mixing applications and must comply with stringent hygiene standards.

View all product categories →Inspection and testing are performed according to the product type and applicable production procedure. Request the inspection scope for the selected model.
Torque, pressure, temperature, cycle-life, and protection ratings should be taken from the applicable model datasheet or test report, not from a category-wide claim.
Mounting interfaces and standards such as ISO 5211, NAMUR, VDI/VDE 3845, or other requirements are confirmed for each selected product and configuration.
Body, shaft, gear, seal, coating, and fastener materials vary by series. Confirm the bill of materials and environmental suitability before ordering.
CE, ATEX, IECEx, SIL, IP, and other documentation applies only where stated for the exact model. Certificate scope and revision should be verified during selection.
Warranty period, exclusions, spare-parts support, and technical documentation are confirmed in the quotation, order documents, or product-specific warranty terms.
Reliable actuator performance depends on appropriate materials, controlled machining, surface treatment, sealing, and assembly. Material grades and treatments vary by model and should be confirmed in the applicable datasheet.
Compared with an untreated surface, the hard-anodized cylinder surface is designed to improve wear and corrosion resistance.

One size doesn't always fit all. We understand that some applications require specific adaptations. That's why we offer a wide range of customization options to ensure our pneumatic actuators perfectly match your unique requirements.
Selection Basis: Choose based on torque requirements and application.
Common Types:
Rack and Pinion: Available output torque depends on the selected series and air pressure; refer to the model torque table.
Scotch Yoke: Suitable for high-torque and large-valve applications; confirm output torque using the selected model’s torque table and operating pressure.
Selection Basis: Choose based on required functionality (fail-safe operation, air consumption, etc.)
Common Types:
Double-Acting: Requires air to open and close. Typically A port opens, B port closes.
Spring-Return: Uses air in one direction and spring force in the return direction. Select fail-close or fail-open according to the process safety requirement.
Customer Provides Torque: Easiest selection if customer provides valve torque with safety factor. Compare actuator torque (at specified air pressure) to valve torque + safety factor.
Customer Provides Information: If customer is unsure of torque, provide valve type, seal material, and size for model selection.
Emphasis: For spring return actuators, the spring torque is the critical factor to compare against the valve torque + safety factor. For double-acting actuators, compare the torque at the specified minimum available air pressure with the valve torque and the required safety factor.
Customization: Non-standard rotation angles may be available for selected actuator series.
Options:
0°–180°
0°–120°
0°–135°
Three-Position: Typical positions may include 0°–45°–90°. Available angles depend on the selected model and control arrangement.
Required Information: Specify the required rotation range, intermediate positions, valve torque, and control method.
