48" Wafer Style Butterfly Valve Ductile Iron Body Lever Operated Manual

Ductile Iron Body lever operated wafer type manual butterfly valve

The butterfly plate of the wafer butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical
channel of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between
0°-90°, which can play a role in flow adjustment. When the butterfly plate rotates to 90°, the valve reaches the maximum Opening.
The wafer butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover,
it can be opened and closed quickly by rotating 90°, and the operation is simple. At the same time, the valve has good fluid
control characteristics.

Butterfly valve is also called flap valve, is a simple structure of the regulating valve, can be used for low-pressure pipeline medium switch control butterfly valve refers to the closing parts (disc or butterfly plate) for the disc, revolving around the valve shaft to open and close a valve.

Valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media and other types of fluids. It mainly plays a cutting and throttling role in the pipeline. Butterfly valve opening and closing part is a disc disc, in the valve body around its own axis rotation, so as to achieve the purpose of opening and closing or regulating.

By operating temperature:

(1) high temperature. t> 450 °C butterfly valve.

(2) medium temperature butterfly valve. 120 C< t< 450 ℃ butterfly valve.

(3) normal temperature butterfly valve. A 40 c & lt; t< 120 °C butterfly valve.

(4) low temperature butterfly valve. A 100 & lt; t< A 40 °C butterfly valve.

(5) ultra-low temperature butterfly valve. t< 100 °C butterfly valve.
