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.

V-type regulating ball valve is composed of pneumatic actuator and V-type ball valve, and the valve core is ceramic. The V-shaped opening ball has a shearing effect with the valve seat. When the medium contains fibers or solid particles, the V-shaped ball will not be stuck, and good sealing is still ensured. The valve core is made of ceramic, which has high abrasion resistance. The valve seat protection ring can prevent the fluid from directly washing the valve seat, and extend the service life of the valve seat.
