Description

Rack and pinion pneumatic actuator is a type of actuator that uses compressed air to move a piston that is connected to a rack and pinion mechanism. The rack is a straight, toothed bar, while the pinion is a small, toothed wheel that engages with the rack. When the pneumatic actuator receives a signal, the compressed air enters the piston chamber and pushes the piston, which moves the rack and pinion. As the rack moves, it rotates the pinion, which, in turn, moves the output shaft or valve stem. The output shaft or valve stem is typically mounted on the top of the actuator and moves in a rotational motion to adjust the position of a valve or other control element. This type of actuator is commonly used in process control applications, such as in the oil and gas industry, chemical plants, and power generation plants.

Technical Features

1. Anodized Cylinder Block

Anodized cylinder body refers to the surface of the cylinder body is anodized to form a layer of coating with wear resistance, corrosion resistance, high hardness and high heat resistance. It can enhance the service life and performance of the cylinder block, and is suitable for working in harsh environments such as high pressure, high temperature, and high corrosion. In addition, anodic hardening can also improve the lubricity and dimensional accuracy of the cylinder, making it more suitable for the use of precision machinery.

2. Piston structure

The double-piston rack-and-pinion structure makes it compact in structure, symmetrical in installation, long in service life and fast in action. Reversible in the field by simply flipping the piston, the piston is anodized for greater corrosion and wear resistance.

3. Two independent external travel limit adjustments

As a standard actuator, the travel limit is adjustable from -5° to 10° in the closed position and -5° to 10° in the open position. In this way, the valve stroke can be adjusted accurately, the stroke can be set and a large stroke adjustment range can be provided.

4. Versatile drive shaft with break-resistant construction

It is easy to switch between parallel squares and diagonal squares, and double square structure (diagonal and parallel) drive shafts are also available. These two solutions facilitate more flexible and lower inventory.

5. Top Adapter for Drive Shaft

In relatively high temperature occasions, the top aluminum alloy adapter connected to the accessory is more accurate and stable when matched with the accessory drive shaft. It is suitable for both single square (diagonal or parallel) and double square structure drive shafts and both able to provide.

6. A compact and stylish structure

Double-acting and spring return (single-acting) actuators have the same cylinder and end cover to reduce inventory, and the action mode can be changed in the field by adding and removing spring assembly modules.

7. Location Indication

he new top adapter is combined with the new valve position indicator, and the position indication of the actuator/valve can be easily adjusted by simply rotating the top adapter and the position indicator 90°. This operation can also be conveniently done on site without dismantling the actuator.

8. Composite bearings and guide rings

Composite bearings on piston and rack provide precise operation, low friction, and long life. The piston guide ring prevents the output shaft from breaking.

9. Combined preload spring

The spring seat of the high-grade coated steel structure is single and versatile, which is safer and corrosion-resistant.

10. Nickel-plated drive shaft

Fracture-resistant construction, bearing guidance for increased safety and maximum service life of the drive shaft.

11. Machining precision teeth

Piston rack and drive shaft gear can achieve precise positioning, small backlash and maximum meshing can achieve high-efficiency operation in the whole process.

12. Selection of high quality bearings and seals

Wide operating temperature range, low friction, long life.

13. Screw Fastener

Stainless steel bolt fasteners provide long-term corrosion resistance.

14. Fully compliant with various international norms

The products provided are in full compliance with international standards such as ISO5211, DIN3337 and VID/VED3845, which can better achieve interchangeability and more convenient installation of valves and various accessories.
