The Operation Theory of 12″ Butterfly Valve

The operation theory of a 12″ Butterfly Valve involves regulating fluid flow through a rotating disc. This design, similar to a 16 butterfly valve, enables precise control in various applications. With 3 butterfly valves, including AWWA butterfly valve and butterfly flange valve, it ensures efficient flow management. As the disc rotates perpendicular to the flow direction, it opens or closes, allowing or restricting fluid passage. This mechanism, coupled with robust construction, ensures reliable performance in industrial settings.

Relevant Information about 12″ Butterfly Valve

1. Rotor: The rotor is the part of the valve that rotates to open or close the flow path. In a butterfly valve, it’s the disc that pivots.
2. Stator: The stator is the stationary part of the valve, typically consisting of the valve body and seat. It provides support and creates a sealing surface for the rotor.
3. Universal Joint: The universal joint connects the actuator to the valve shaft, allowing for rotational movement. It ensures that the motion from the actuator is accurately transmitted to the valve.
4. Shaft Seal: The shaft seal prevents leakage along the valve shaft where it passes through the valve body. It’s crucial for maintaining the integrity of the valve and preventing fluid loss.
5. Driving System: The driving system includes the actuator and associated mechanisms that provide the force to operate the valve. It can be manual, pneumatic, or electric, depending on the application requirements.
