The manufacturer of single acting pneumatic actuator tells how to select the actuator
When our pipeline needs an actuator control valve, we all want to choose a more appropriate and cost-effective pneumatic actuator. First, we need to know the types and functions of pneumatic actuators. Actuator can be divided into pneumatic actuator, hydraulic actuator and electric actuator. There are three kinds of commonly used actuators, and we usually choose pneumatic actuators when purchasing. When selecting the pneumatic actuator, the torque required by the pneumatic actuator to drive the valve shall be selected according to the size of the air source. In general, 30% allowance is made for torque.
Secondly, we evaluated the installation platform, and we can select pneumatic actuators according to the environment of each working condition. There is a standard for pneumatic actuators. We should find the appropriate standard pneumatic actuator according to the torque of the valve.
For example: electric actuator column, electric switch type. Passive contact type and regulating type. We can choose according to the valve flow. A hydraulic actuator is an example. The hydraulic actuator has a single and dual function. According to customer requirements and oil pressure, appropriate hydraulic actuator can be selected to drive the valve
