Huaying clamp type stainless steel butterfly valveMaintenance:

1. During the use of pneumatic butterfly valves, they should be kept clean regularly, and the transmission threads must be lubricated regularly. If a fault is found, it should be immediately stopped and the cause should be identified and cleared.

2. The bolts of the packing gland should be tightened evenly and should not be pressed into a crooked state to avoid collision, obstruction of valve stem movement or leakage.

3. During installation, the valve can be directly installed on the pipeline according to the connection method. In general, it can be installed at any position in the pipeline, but it needs to be easy to operate and maintain. Note that the flow direction of the shut-off valve medium should be upward from below the longitudinal valve disc, and the lift check valve can only be installed horizontally.

4. When using a pneumatic butterfly valve, it should only be fully open or fully closed, and it is not allowed to adjust the flow rate to avoid erosion of the sealing surface and accelerated wear. There is a reverse sealing device inside the gate valve and the upper threaded globe valve. By turning the handwheel to the upper position and tightening it, the medium can be prevented from leaking from the packing.

5. When opening and closing the pneumatic butterfly valve, use a handwheel and do not use levers or other tools to avoid damaging the valve components. Clockwise rotation of the handwheel is considered closed, while counterclockwise rotation is considered open.

6. Before installation, it is necessary to carefully check whether the pressure and diameter marked on this valve meet the usage requirements, eliminate defects caused by transportation, and remove dirt from the valve components.

7. Valves stored for a long time should be regularly inspected, and the exposed processing surfaces should be kept clean and free of dirt. During storage, the ball valve should be blocked at both ends and in an open state, and the pneumatic butterfly valve and channel should be blocked at both ends and in a closed state. They should be neatly stored indoors in a ventilated and dry place, and stacking or outdoor storage is strictly prohibited.
