The butterfly valve, also called the flap valve, is a valve with a simple structure. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate, which rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment.
The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, simple and fast in operation, but also has good flow regulation and closing and sealing characteristics at the same time. It has been developed in the past ten years. One of the fastest valve varieties.
Butterfly valves are widely used. Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, and liquid metal. It mainly plays the role of cutting off and throttling on the pipeline.
The variety and quantity of butterfly valves continue to expand, and are developing towards high temperature, high pressure, large diameter, and high sealing. Now butterfly valves have long service life, excellent adjustment characteristics, and one valve with multiple functions. Its reliability and other performance indicators have reached a high level.
The motorized butterfly valve is composed of electric actuator and butterfly valve. According to different working modes and working conditions, it can be divided into switch control type and intelligent adjustment type. The sealing form is divided into soft seal and hard seal. Through the electric actuator, the rotating valve rod drives the disc plate to open and close in the range of 0°-90°.

The lining material uses FEP (F46) and PCTFE (F3) and other fluoroplastics, which can be applied to various concentrations of sulfuric acid, hydrochloric acid, hydrofluoric acid, and Water and various organic acids, strong acids.

In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis of the valve stem, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the valve is in a fully open state. Rubber lined butterfly valve should generally be installed horizontally in the pipeline.
