Pneumatic actuated ball valve is an automatic valve. Using clean air as the driving source to drive the valve to open or close. The advantages of it are low cost, explosion-proof, environmental protection, and fast switching speed. It can be applied to various industries, such as wastewater treatment, waste gas treatment, garbage treatment, ventilation pipes, shipbuilding and so on.
In this article, we will introduce you to 3 guidelines for choosing a pneumatic ball valve. Hope to help you pick the right valve for your project and help your project run better.
1. Actuator
Pneumatic actuators are divided into two types according to their specifications, one is spring return type, and the other is double-acting type.
Spring return type actuators are air to open, then it will auto close once the air is interrupted.
Double acting type actuators are air to on, air to off.
You could choose the right type of pneumatic actuator according to your needs.
2. Torque Range
Different styles of pneumatic actuators have different torque ranges.
AT series actuator with torque range from 5.7Nm to 4,678Nm
AW series actuator with torque range from 185Nm to 157,300Nm
Scotch Yoke type actuator with torque range from 500Nm to 40,000Nm
Choosing an actuator with a suitable torque range can ensure the opening and closing of the valve, so as to avoid affecting production efficiency because it cannot be opened or closed.
3. Ball valve
