A Brief Discussion On How To Extend The Service Life Of Pneumatic Butterfly Valves

Sanitary Butterfly Valve has a wide range of applications in our daily life. When using pneumatic butterfly valves, the correct method of use can effectively maintain the pneumatic butterfly valves in time, so that they have a longer operating life. Let's take a look at how to use pneumatic butterfly valves to extend their service life.
Pneumatic butterfly valves can make full use of the air source pressure, which is some users do not know these principles. This is because they are not very familiar with pneumatic butterfly valves. Pneumatic butterfly valves can use the air source pressure to take away some dirty media that are not easy to get out. This is very effective for pneumatic butterfly valves to improve the safety of pipelines.
Correct use of pneumatic butterfly valves:
1. When using pneumatic butterfly valves, only fully open or fully closed, not allowed to adjust the flow, so as to avoid erosion of the sealing surface and accelerated wear. There is a reverse seal installation in the gate valve and the stop valve. The handwheel is rotated to the upper position and tightened to prevent the medium from leaking from the packing.
2. During the use of pneumatic butterfly valves, they should always be kept clean, and the transmission threads must be regularly lubricated. When a fault is found, it should be stopped immediately, and the cause should be found out to eliminate the fault.
3. The bolts of the packing gland should be tightened evenly and should not be pressed into a crooked state to avoid damage to the valve stem or leakage.

4. Before installation, it is necessary to carefully check whether the pressure and diameter of the valve mark meet the application requirements, eliminate the defects caused by the transportation process, and clean the dirt on the valve parts.

5. When installing, 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 to be easy to operate and maintain.

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

7. Butterfly valves that are stored for a long time should be checked regularly, and the exposed processed surface must be kept clean and clean of dirt. When stored, both ends of the pneumatic butterfly valve channel should be blocked and in an open state, and stored neatly in a ventilated and dry place indoors. Stacking or outdoor storage is strictly prohibited.
