The valve should be placed in a ventilated and dry privilege, and the two ends of the valve should be blocked. Both pneumatic ball valves and pneumatic butterfly valves need to keep drying.
If the time is stored, it should be checked regularly, clean up regular cleaning, and the oil is applied after cleaning.
After installation, we must also check if the valve is working and aging. The main items include:
Sealing surface wear; ladder thread wear of the valve stem and the stem nut; whether the filler has expired, if there is damage, it should be replaced in time; after the valve test is installed, the sealing performance test should be performed.
The valve also regularly injects grease into the oil, in order to use a longer time, allowing the valve to play a normal function and can increase service life.
When injecting oil, don't ignore the quality of the grease, the quality of the oil is very important, but some oils do not only protect the valve, but there may be side effects, so when choosing grease, try to choose better oil. When the grease is injected into the valve, it should be injected according to different valve sizes and instructions, and can be calculated according to the size of the valve, then calculated, and then injective injection.
