Relevant Information about 8″ Butterfly Valve
- Rotor: The rotor is the rotating part of the valve responsible for controlling the flow of fluid. In a butterfly valve, it’s the disc that pivots to open or close the flow path.
- Stator: The stator refers to the stationary part of the valve, typically the valve body and seat. It provides support and creates a sealing surface for the rotor to operate against.
- 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.
- Shaft Seal: The shaft seal prevents leakage along the valve shaft where it passes through the valve body. It’s a crucial component for maintaining the integrity of the valve and preventing fluid loss.
- Driving System: The driving system consists of 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.
