Steps for Converting a Manual Butterfly Valve into a Pneumatic Butterfly Valve
Can a manual ordinary butterfly valve be refitted into a pneumatic butterfly valve? The answer is yes.
I. Purchase a Pneumatic Actuator
To convert a manual ordinary butterfly valve into a pneumatic butterfly valve, a pneumatic actuator needs to be installed. First, it is necessary to purchase a suitable pneumatic actuator according to the requirements of the butterfly valve, including parameters such as the model, resolution, and material of the actuator. When purchasing, factors such as the working pressure, temperature, and medium of the system need to be considered.
II. Adjust the Structure of the Butterfly Valve
Before installing the pneumatic actuator, the structure of the manual ordinary butterfly valve needs to be adjusted. First, devices such as the handwheel, handle, or bolts need to be removed, and then the pneumatic actuator needs to be installed. During the adjustment process, attention should be paid to the sealing performance of the butterfly valve and the tightness of the connection.
III. Connect the Pipeline
The manually adjusted ordinary butterfly valve needs to be connected to the air source pipeline. Generally speaking, the air source pipeline needs to be connected to devices such as a pneumatic pressure regulator, a manual changeover valve, and an air pipe to ensure the normal operation of the pneumatic butterfly valve. During the connection process, the sealing performance of the pipeline needs to be checked to prevent air leakage.
IV. Debugging
After the connection is completed, the pneumatic butterfly valve needs to be debugged. It is necessary to check in sequence whether devices such as the air source supply, the manual changeover valve, the pneumatic pressure regulator, and the air pipe are normal, and observe whether the starting and shutting-down states of the actuator are good. In addition, the actuator needs to be adjusted to achieve a reasonable opening and closing state of the butterfly valve.
Through the above steps, we can upgrade a manual ordinary butterfly valve to a pneumatic butterfly valve. This can not only improve the control performance and accuracy of the butterfly valve but also reduce the work intensity and improve work efficiency. When operating, attention should be paid to the operation feel and stability of the butterfly valve, and the pneumatic butterfly valve should be regularly maintained
