What kind of media can this electric ball valve be used on? First of all, air. For air, its pressure is very small in the product itself, but its density is also small. Therefore, if a valve fails to meet its own requirements in terms of its structure, it will not be able to meet the adaptability of this medium when it is used in the product. But when it is produced, Because it meets the very good requirements, it can also achieve the maximum adaptability in this respect. Another aspect is that for current users, they will use it on steam.

How to make the pneumatic ball valve have a longer service life and stable performance? The following elements must be noted:
1、 Before use, clean the dirt and iron chippings of the pneumatic valve with cold water.
2、 When the pneumatic valve is turned off, there are still some residual substances in the valve. It is necessary to disconnect the switch power supply and the source to carry out the removal, so as to completely release the working pressure of the valve body.
3、 Generally, valves use sealing materials to prevent leakage and damage, and the sealing materials must be removed on time.
4、 The nuts and anchor bolts on the flange shall be fixed firmly to prevent the damage or crack of the cushion surface caused by uneven review in the middle of the flange surface, which may cause leakage of substances from the valve flange connection.
5、 If the valve works outdoors for a long time, it will cause corrosion of the valve and components, which will make it impossible to use the valve normally. Therefore, it must be maintained and tested to ensure the smooth operation of the performance
