Tightness and strength test:
(1) Strength test, No leakage is observed to prove that the valve body strength is qualified.
(2) Sealing test: nitrogen is generally used as the medium; Close the pneumatic ball valve, and then inject nitrogen into the pneumatic ball valve from the pressure test valve on the sleeve. The pressure rises to 1.1 times of the nominal pressure of the pneumatic ball valve, and the middle chamber pressure relief valve is connected with the hose to the water container for detection. The insertion depth is 1cm; If there is no bubble within 5min, the valve sealing is qualified.

What are the characteristics of electric ball valve? In the whole industrial production process, many of us have already known that some high-tech tools must be put into use in this process, and these tools are also very common in our real life. But it is not easy for us to choose the most suitable and professional tool, especially now that industrial production has reached the top level, and every step should be strictly required. Therefore, under such conditions, more and more industrial producers have begun to seek a professional production tool that is the most professional and can meet all requirements. At this time, many people have begun to pay universal attention to the electric ball valve as an industrial production tool, because with the continuous development of the times, Many industrial production has begun to use such a tool with new development efficiency.
