What Is The Advantage for Butterfly Valve
Butterfly Valve is a simple structure control valve,it can be used for switching control of low pressure pipeline medium. Our Butterfly Valve is a kind of valve that the disc rotate around the valve shafts to open and close.
1, opening and closing convenient and rapid, labor saving, fluid resistance is small, can often operate.
2, simple structure, small size, short structure length, small volume, light weight, suitable for large diameter valve.
3, can transport mud, the least liquid in the pipe mouth.
4. Good sealing can be achieved under low pressure.
5, good adjustment performance.
6. When fully opened, the effective flow area of the valve seat channel is large and the fluid resistance is small.
7. The opening and closing torque is small, because the butterfly plate on both sides of the rotating shaft is basically equal to the effect of the medium, and the torque is in the opposite direction, so the opening and closing is less effort.
8, sealing surface material is generally rubber, plastic, so the low pressure sealing performance is good.
9. Easy installation.
10, the operation is flexible and labor-saving, manual, electric, pneumatic, hydraulic mode can be selected.
Butterfly valve simple structure, small size, light weight, its components are relatively few, on the key several parts can form the butterfly valve, open time is also very convenient, only need to choose the switch to 90 degrees, butterfly valve fluid control is very good, can increase the flow or reduce the flow at any time, the valve in the transport of any fluid when there is a certain resistance, The resistance of the butterfly valve mainly comes from itself, such as the thickness of the butterfly valve body. If you want to reduce the resistance to the fluid, you only need to reduce its thickness.
Elastic seals have temperature-limited defects.
The use of butterfly valve is also relatively wide, if used to control the flow then you need to choose a different type and the size of the valve body, because the butterfly valve in the design itself is more suitable for some large diameter valves. Butterfly valve is not only widely used in petroleum, gas, chemical, water treatment and other general industry, but also used in the cooling water system of thermal power station.
