Check whether there are foreign matters inside the valve. If there are foreign matters, the opening and closing ports of the valve will be stuck. The valve can be started normally only after the foreign matters are removed. When cleaning, be careful and quickly remove all foreign matters. More "spa" pneumatic on-off ball valves are provided. The advantage of pneumatic on-off ball valves over other valves is that the sealing of pneumatic ball valves is strong. The key is to do a good job in the maintenance of pneumatic butterfly valves for long-term storage. What are the main tasks to be done in the installation and assembly of electric ball valves
