What is Butterfly Valve Working Principle?
There are various types of valves available in the butterfly valve range. The offset disc of Butterfly Valves comes with the technique like hand wheel operated, gear operated, electric operated and pneumatic operated. The aim of using a butterfly valve is for isolating or regulating the flow of liquid. The closing technique takes the form […]

The Type of Grooved Butterfly Valve
There’re two sealing types for butterfly valve—metal sealing and elastic sealing. Valves that use metal sealing usually last longer than valves that use elastic sealing, but they are difficult to be completely sealed. Metal sealing can endure high working temperature while elastic sealing is limited to changes in temperature. If the butterfly valve is used […]

Introduction of the Driving Mode of Sanitary Butterfly Valve
Sanitary butterfly valves are widely used in the sanitary field. It is called butterfly valve not because of its shape like a butterfly, but because of the simple structure, easy to use, compact appearance and flexible opening and closing. The butterfly is also small and flexible insects and there are a lot of similarities, so this […]

Butterfly Valves in Different Working Conditions
As the movement of the plate of butterfly valve has a wiping effect, most butterfly valves can be used in medium with suspended solid particles. Depending on the strength of the sealing member, they can also be used in medium of powder and granule. The structural length and overall height of sanitary butterfly valve are small. […]

The advantages of sanitary butterfly valves
The advantages of sanitary butterfly valves include: 1. The butterfly valve rubber sealing and valve plates are imported, ensuring the performance and service life of the butterfly valve. 2. High-precision CNC is used to lathe the valve to ensure reliable interchangeability of the butterfly valve, saving the trouble of uncertain performance due to change of rubbers. […]

Flanged Sanitary Butterfly Valve Introduction
Flange sanitary butterfly valve disc center of rotation (i.e., the center of the valve stem) is located in the centerline of the valve body and disc sealing surface cross-section. Its seat is made of synthetic rubber. When it is closed, the external sealing surface of the disc presses the synthetic rubber valve seat to make […]

The Use of Pneumatic Butterfly Valve in Different Medium
When sanitary butterfly valve is used for control of solid materials, it’s often used at the bottom of cans as discharge valve. Since dust materials mostly contain particles large and small, the wear on the valve sealing surface is a sure thing. Improper selection of the model will greatly reduce the service life of the valve, […]

The Comparison between Ball Valve and Butterfly Valve
1. In terms of sealing performance, sanitary ball valve is better than sanitary butterfly valve. Ball valve has a two-way zero leakage. Butterfly valve has a two-way ANSI V-class standard (no visible leakage). Therefore, both are sufficient to meet the needs of heating pipe network and the normal maintenance and repair of the pipe network will […]
