be careful:
1. The identification arrow on the upper side of the pneumatic ball valve must be consistent with the flow direction of the gas during operation;
2. In order to prevent foreign substances from flowing into the pneumatic ball valve during welding operation, the inner surface of the pneumatic ball valve is blocked with a packaging bag;
3. The pipe and pneumatic ball valve shall be welded horizontally and vertically;
4. It takes about 30 minutes for the welding machine to cool down after separation;
5. Take out the T-type pneumatic ball valve handle from the box, and insert the handle into the knob completely after assembly. Note: When using the "T" handle, test the on-off state of the pneumatic ball valve;
6. To confirm whether the pneumatic ball valve has on-off action: the length and direction of ADAPTER linear PE pipe of the pneumatic ball valve must be marked (-), which is open at this time. The linear vertical direction indicator (‖) is now closed. CLOSE: Turn ADAPTER 90 clockwise when it is on. Open (open): Turn ADAPTER 90 counterclockwise in the closed state. TOP ADAPTER of GEAR BOX? At about 180, the turning arrow 90 switch moves to the FULL CLOSE state, and the FULL OPEN state cannot be opened or closed vigorously.
7. Air tightness test using vent pneumatic ball valve;
8. Sand shall be laid around the knob of pneumatic ball valve.

Composition of plastic coated pneumatic butterfly valve
At present, there are a lot of plastic coated pneumatic butterfly valve products used by people, which have many good characteristics in the process of application, and the time of application can better ensure the improvement of the service life of this product. So what are the components of this product? People should stop carefully understanding, I got a lot of good assistance from it.
The plastic coated pneumatic butterfly valve is mainly composed of three parts, of which the main skeleton is the pneumatic butterfly valve, and then PVC materials are sprayed on the outside to improve the application of the whole pipeline without much corrosion damage. Another important part is the joint, which has many different specifications, There are many kinds of metal tube structures, which should be selected according to different application environments, so that people can get good assistance from the application process.
So when you choose to purchase this plastic coated pneumatic butterfly valve equipment, you should fully understand the local characteristics of these three different components, so as to better stop the purchase according to the practical application environment of people, and ensure the good sealing performance after use. In addition, the application and operation of this hose device should also be carefully understood and controlled by the purchaser, It can better ensure that there will be no leakage and other problems during operation.
