1. The pneumatic butterfly valve should be kept clean during the operation process. It is necessary to regularly lubricate the transmission thread. When it is found to be faulty, it should be stopped immediately to find out the cause and eliminate the problem.

2. The bolts of the packing gland should be evenly tightened, and should not be pressed into a smashing condition to prevent the bump from hindering the movement of the valve stem or forming a leak.

3. When the equipment is used, the valve can be directly connected to the pipeline according to the connection method. Under normal circumstances, the equipment can be in any direction of the pipeline, but it is easy to operate. Note that the flow direction of the shut-off valve should be upward from the longitudinal valve, and the lift check valve can only be horizontal.

4. When the pneumatic butterfly valve is used, it is only fully open or fully closed. It is not allowed to adjust the flow to avoid erosion of the sealing surface and accelerate wear. There is a reverse sealing device in the gate valve and the upper thread stop valve. When the hand wheel is screwed to the upper direction, the medium can be prevented from leaking from the packing.

5. When the pneumatic butterfly valve is opened and closed, use the handwheel. Do not use levers or other tools to avoid damage to the valve. The handwheel rotates clockwise to close, and vice versa.

6. Before the equipment, it is necessary to carefully check the pressure of the valve mark, whether the diameter meets the application requirements, eliminate the shortcomings caused by the transportation process, and eliminate the dust of the valve parts.

7. Long-term registered valves should be regularly reviewed. The exposed surface should be kept clean and cleaned of dust. When stored, the ball valve should be blocked at both ends and open. Pneumatic butterfly valve, the two ends of the channel should be blocked and closed. Stored in a ventilated and dry place indoors, no stacking or open storage.
