Specifications:
Butterfly Valve is a kind of regulating valve with simple structure, which can be used for on-off control of low-pressure pipeline medium.
Butterfly valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays the role of cutting and throttling on the pipeline. The butterfly valve opening and closing part 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.
1. Small in size, light in weight, easy installation and maintenance.
2. Simple and compact construction, quick 90 degree on-off operation.
3. Minimized operating torque, energy saving.
4. Flow curve tending to straight line, excellent regulation performance.
5. Long service life, standing the test of tens thousands opening/closing operations.
6. Wide selection of materials, applicable to various medium.
