Butterfly Valve

The operation methods of butterfly valves are diverse, generally divided into manual, electric, pneumatic, hydraulic, etc. In terms of manual operation, the lever length of the butterfly valve should be moderate, the operating force should be light, and easy to control. In terms of electric and pneumatic operation, butterfly valves often use manual spring return mechanisms to ensure that they can still automatically close in the event of sudden power outages or other abnormal situations.
