How Do Pneumatic Valve Actuators Work?

Compared to electric models, pneumatic valve actuators feature fewer moving parts and only use proportional controls or simple on or off signals to create movement in the valve systems. When compressed air enters the device, it pushes air to the diaphragm or piston, causing it to open or close the valve stem. This type of actuator acts like a simple air-powered engine for your valve, delivering reliable and efficient performance.

Discover some of the common types of pneumatic valve actuators:

• Spring-return pneumatic valve actuator: Pushes the valve only in one direction
• Double-acting pneumatic actuator: Opens and closes the valve
• Pneumatic globe valve actuator: Uses a linear motion
• Pneumatic rotary valve actuator: Produces a rotational motion

Common Applications in Various Industries 

The pneumatic components of this type of valve actuator keep your operations running smoothly and safely, even without electrical energy. They are purpose-built to operate effectively in a wide range of temperatures and hazardous environments.

They make a suitable option for many industries with key applications, including: 

• Industrial process control: Automated valve control enables rapid movement to regulate various industrial processes, including the flow of gases and fluids in pipelines, heat exchangers and reactors.
• HVAC system operations: Pneumatic control systems respond to changes in humidity, temperature and static pressures, which are critical in maintaining steady, clean airflow in HVAC systems. 
• Production machinery automation: Pneumatic components are integrated into production lines and machinery to seamlessly and safely control fluid flow and other mechanical functions. 
• Water and wastewater management: These valve actuators help deliver smooth flow and direction for water treatment plants.
• Power generation: The pneumatic design of the actuator control provides a safer choice in plants and other industrial settings where electrical sparks or combustion are generally avoided. 
• Mining operations: These actuators can operate in harsh, explosive environments, making them ideal for mining operations.
