The introduction of these two aspects is enough to let you understand the pneumatic control valve, and let you use it better in the process of use, and ultimately will not affect your use of it. I believe we all know this very well! Because these basic knowledge are very important. The sealing performance of pneumatic butterfly valves with different relevant information is different. Only by following the rules can the installation of electric control valves be more smooth. How to purchase pneumatic control valves? The basic question is how to use the electric butterfly valve? How to maintain the electric butterfly valve in the forbidden area of overload? All aspects should be considered

The butterfly valve is simple in structure, small in size and light in weight, and only consists of a few parts. The valve can be quickly opened and closed only by rotating 90 °. The operation is simple. Together, the valve has outstanding fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body, so the pressure drop through the valve is very small, so it has good flow control characteristics. Butterfly valve has two sealing types: elastic seal and metal seal. For elastic sealing valve, the sealing ring can be embedded on the valve body or attached to the periphery of the butterfly plate.
