The main advantages of the butterfly valve are simple structure, small size and light weight, and low cost. The pneumatic butterfly valve is particularly prominent. It is installed in the high air tunnel, and is easy to operate through the control of the two position five way solenoid valve, and can also adjust the flow medium. The fluid resistance is small, the effective flow area is large when the pneumatic butterfly valve with medium and large diameters is fully opened, and the opening and closing is fast and labor-saving. The disc wrench can complete the opening and closing by rotating 90 degrees. Since the force of the disc wrench medium on both sides of the rotating shaft is nearly equal, the torque direction generated is opposite, so the opening and closing torque is small, and good sealing can be achieved under low pressure. The sealing materials of the butterfly valve include nitrile rubber and fluororubber, The edible rubber is lined with tetrafluoroethylene, so the sealing performance is good. The hard sealing butterfly valve is a soft and hard laminated metal plate, which has the heavy advantages of hard metal sealing and elastic sealing. It has excellent sealing performance no matter at low temperature?

How to install the connector of pneumatic butterfly valve
As for the pneumatic butterfly valve, the connector is also very important. What I want to introduce today is how the connector of the pneumatic butterfly valve should be installed.
At present, the hose connectors on the market mainly include thread connection, flange connection, quick connector connection and other types. Different types have different uses. The data of the main parts of the pneumatic butterfly valve are made of austenitic stainless steel, which ensures the excellent temperature resistance and corrosion resistance of the pneumatic butterfly valve. Moreover, there are many types of pneumatic butterfly valve connectors, The specification is mainly based on the size of the inner diameter to select the appropriate product, and it should also distinguish between inch thread and metric thread. The specifications are different.
As for the models of pneumatic butterfly valve connectors, the main difference lies in the meaning of some threads, such as NPT, PT, G, etc., which have different meanings. Consumers should understand the meaning of these connectors when purchasing, and then stop purchasing according to their own needs. Different models correspond to different connectors.
In fact, the connection model of pneumatic butterfly valve is corresponding to that of pneumatic butterfly valve, so some aspects should be paid attention to when selecting. The first is the selection of connection mode. Generally speaking, it mainly includes flange connection, thread connection and quick connection connection. You should stop selecting according to your practical needs. The second aspect is pressure. The selection of gathering and transmission hoses and connectors should be based on the pressure of practical work, so as to ensure smooth work, and the acceptable pressure and temperature of metal pipe connectors, the corrosiveness of media, etc.
