Manual wafer butterfly valve
Butterfly Valve
Brief of Product
Butterfly valve, also called the flap valve is a kind of simple structure of the regulator, it can be used for low pressure pipeline medium of switch control which refers to the closed butterfly valve (valve clack or butterfly plate) is a disc, the valve can reach open and close by rotating around the valve, it can be used to control air, water, vapor, mud, all kinds of corrosive medium, oil, liquid metal and radioactive medium such as various types of fluid flow. Its function in the line is mainly to cut off and throttle. Butterfly valve opening and closing is a disc-shaped butterfly plate, the body rotatesaround its own axis, so as to achieve the aim of opening and closing or adjust.

Advantages
It is simple in shape, short in structure, good in manufacturability, and wide in scope of application.
With first-class machining centers and processing equipment
Applying new industries to comply with national and industry standards
Quality is stable: carry out the whole process quality control, meticulous and omnidirectional detection.
The fluid resistance is small, and the seal is eroded and eroded by the medium. Opening and closing is more labor-saving.
