If the low-temperature ball valve is stored for a long time and does not work, please check the parts on it. If there is dirt on it, apply some anti-rust oil after cleaning. Check the low-temperature ball valve before each installation and use. The main inspection item is the sealing surface. Wear, valve stem and thread wear. If there is no problem, you can open it and use it normally.

Method ②: accurate sealing performance test

After the cryogenic ball valve is opened, a sealing performance test should be carried out first. Especially for the ball valve in operation, pay more attention to the integrity and fluency of each component, especially the flange threads and the bolts on the bracket. If the threads are intact and there is no looseness, you can open the operation. During the entire operation, pay attention Install the corresponding protective cover on the valve stem to keep the entire cryogenic ball valve scale clear and complete, so as to keep the cryogenic ball valve stable in use.
