1、 Features of fixed pneumatic ball valve:
1. Double blocking and discharging function: the fixed pneumatic ball valve uses the spring to pre tighten the floating valve seat. No matter the valve is in the fully open or fully closed state, the valve seats at the upstream and downstream sides block the fluid, and the residues in the cavity of the valve body are discharged through the discharge valve.
2. Automatic pressure relief function: in case of abnormal pressure rise caused by the temperature rise of the medium staying in the valve body cavity, it is not necessary to pass through the safety valve, but only the valve seat function can automatically relieve pressure, which is very important to ensure the safety of the valve when delivering liquid medium.
3. Fire safety structure: all valves have fire safety functions, and their design and manufacture comply with API 607 and API 6FA specifications.

Second, pay attention to cleanliness when using. When using the electric ball valve at ordinary times, you must pay attention to the maintenance of the product. The ball valve is not a consumable product, but if you never clean and maintain it under frequent use, it will certainly not be used for a long time. Usually, you should pay attention to the timely release of the pressure before and after the ball valve is completed, Then effectively clean the surface of the ball. It is better to disassemble the ball valve regularly to clean all the parts inside. It is convenient to put the ball valve into a special cleaning solution for immersion cleaning.
