How to use pneumatic butterfly valve to have a longer service life

Pneumatic butterfly valves have important applications in our daily lives. How to use the correct method to effectively protect the pneumatic butterfly valve to make it have a longer service life. Let's take a look at how to use pneumatic butterfly valves to have a longer service life.

The correct use method of pneumatic butterfly valve:

1. When the pneumatic butterfly valve is used, it is only used for fully open or fully closed, and it is not allowed to adjust the flow rate, so as to avoid erosion of the sealing surface and accelerated wear. There is an inverted sealing device in the gate valve and the shut-off valve, and the handwheel is turned to the uppermost position and tightened to prevent the medium from leaking from the packing.

2. The pneumatic butterfly valve should always be kept clean during use, and the transmission thread must be regularly lubricated. When a fault is found, it should be stopped immediately to find out the cause and clear the fault.

3. The bolts of the packing gland should be evenly tightened, and should not be pressed into a crooked state, so as to avoid bruising, hindering the movement of the valve stem or causing leakage.

4. Before installation, you must carefully check the pressure marked on this valve, whether the diameter meets the requirements for use, eliminate the defects caused by the transportation process, and eliminate the dirt on the valve parts.

5. During installation, the valve can be directly installed on the pipeline according to the connection method. Under normal circumstances, it can be installed at any position of the pipeline, but it needs easy-to-operate maintenance.

6. Do not use levers or other tools when opening and closing the pneumatic butterfly valve to avoid damage to the valve. Turn the handwheel clockwise to close, and vice versa to open.

7. The butterfly valve stored for a long time should be inspected regularly. The exposed processing surface should be kept clean to remove the dirt. The two ends of the pneumatic butterfly valve channel should be blocked and open during storage. It should be stored neatly in a ventilated and dry place indoors. It is strictly prohibited. Stacked or stored in the open air.
