What is the working principle of the pneumatic butterfly valve?

The working principle of the pneumatic pinch butterfly valve is to use the compressed air 0.4~0.7MPa air source as the power, to fully open and fully close the butterfly valve operation control, can be remote centralized control. Then how to disassemble the pneumatic clamp butterfly valve trachea? Generally, the air pipe is connected to the positioner air inlet. Next, this article will briefly introduce what is the working principle of the pneumatic butterfly valve and how to connect the pneumatic butterfly valve trachea, if you don’t know, come with me to the article to see it! First, what is the working principle of the pneumatic butterfly valve

1. The pneumatic clamping butterfly valve is powered by the air source of compressed air 0.4~0.7MPa, and drives the valve stem to drive the disc to rotate 0~90 degrees in the valve body, so as to control the operation of the butterfly valve fully open and fully closed.

2, the pneumatic clamping butterfly valve can be equipped with a valve positioner according to the working condition requirements, and the input of 4-20mA related signals, so as to control the opening size of the butterfly valve disc, and achieve accurate adjustment of the percentage of parameters such as pressure, flow, temperature and liquid level of the pipeline medium.

3, the pneumatic clamping mold valve can not only be used for local control in the industrial automatic control system, but also for remote centralized control, is one of the preferred system devices in the application of industrial pipelines.

Second, how to connect the pneumatic butterfly valve trachea

Pneumatic butterfly valve is generally controlled by a positioner, and the gas pipe is connected to the positioner air intake port, but it should be noted that the positioner has certain requirements for the air source, and it is best to add a filter pressure reducing valve at the front end to ensure air quality and pressure stability.

The pneumatic butterfly valve is composed of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve is a pneumatic valve that is opened and closed with the circular butterfly plate rotating with the valve stem to realize the enabling action. It is mainly used as a cut-off valve, and can also be designed to have the function of regulating or segment valve and regulating. The butterfly valve is used more and more in low pressure large and medium diameter pipelines.

Categories: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve, carbon steel pneumatic butterfly valve. The main advantages of the pneumatic butterfly valve are simple structure, small size and light weight, low cost, the characteristics of the pneumatic butterfly valve are especially significant, installed in the high-altitude tunnel, convenient operation through the two-position five-way solenoid valve control, and can also adjust the flow medium.
