Unox Single Acting Pneumatic Actuators

What is a Single Acting Pneumatic Actuator?

Single acting pneumatic actuators are mechanical devices that use compressed air to move a piston. In these actuators, air is used to move the piston in only one direction, while a spring returns the piston in the opposite direction.

Working Principle:

It operates by applying compressed air to one side of the piston. This pressure pushes the piston forward, rotating the actuator’s shaft. When the air pressure is cut off, the spring pushes the piston back, causing the shaft to rotate in the opposite direction.

Types:

Available in various sizes, piston diameters, and strokes. They are also manufactured to suit different operating pressures and environments, and they are one type of pneumatic actuator.

Advantages:

• Simple and robust design

• Easy installation and maintenance

• Low cost

• Energy-efficient

• Safe operation

Disadvantages:

• Limited power

• Slow operating speed

• Difficult to achieve precise control

Selection:

When selecting, it’s important to consider application requirements such as necessary power, stroke, operating pressure, and environment.

Installation:

Installation of single acting pneumatic actuators is relatively straightforward. The actuator should be mounted properly and air connections should be correctly made.

Maintenance:

Periodic maintenance is essential for long-lasting and safe operation. Air filters and lubricators should be regularly checked and replaced as needed.

Applications:

Single acting pneumatic actuators are used in various industrial applications, including:

• Automation systems

• Machinery and equipment

• Pneumatic presses

• Valves and dampers

• Conveyor belts

General Specifications:

• Body: Aluminum extrusion

• Pistons: Aluminum casting
