The reasons why choosing butterfly valve
There are many types of valves,apart from the specific working conditions,what are the reason for choosing butterfly valves?
1. Easy to open and close, labor-saving, small fluid resistance, can be operated frequently;
2. Simple structure, small size, short structure length, small volume, light weight, suitable for large diameter valve;
3. It can transport mud and store the least liquid at the pipe mouth;
4. Good sealing can be achieved under low pressure;
5. Good regulation performance;
6. When the valve seat is fully open, the effective flow area of the channel is large and the fluid resistance is small;
7. The opening and closing torque is small, because the butterfly discs on both sides of the shaft are almost equal to the medium, and the direction of the torque is opposite, so the opening and closing is less labor;
8. Easy to install;
9. The operation is flexible and labor-saving, and manual, electric, pneumatic and hydraulic actuators can be selected.
