When choose a pneumatic actuator, there are several important issues to consider:

• Match: Make sure the pneumatic actuator selected matches the required valve size and type to ensure the system will function properly.
• Control mode: According to the process requirements and control needs, select the appropriate pneumatic actuator control mode, such as double-acting or single-acting actuator.
• Environmental conditions: Consider the environmental conditions of the installation location, including temperature, humidity, corrosion, etc., and select pneumatic actuator materials and protection levels that meet the requirements.
• Control signals: Determine the control signal types and interface standards required so that the pneumatic actuator is compatible with the control system.
