The Operation Theory of Wafer Butterfly Valve


The operation theory of the Wafer Butterfly Valve is straightforward and efficient. Similar to a PVC butterfly valve or other sizes like 10 butterfly valve and 12 butterfly valve, it relies on a disc (or “butterfly”) mounted on a central shaft to control the flow of fluid. When the valve is open, the disc rotates parallel to the flow direction, allowing fluid to pass through. Conversely, when closed, the disc rotates perpendicular to the flow direction, blocking the flow. The valve may feature a resilient or metal seated design for enhanced sealing performance, ensuring reliable operation in various applications.

Relevant Information about Wafer Butterfly Valve

  • Rotor (Rator): In a butterfly valve, the disc or “butterfly” acts as the closure element. It rotates within the valve body to control the flow of fluid.
  • Stator: The stator is not typically a component of a butterfly valve. It’s commonly found in motors or generators and serves to provide a stationary magnetic field.
  • Universal Joint: Universal joints are not typically found in butterfly valves. They are commonly used in mechanical systems to transmit torque between non-aligned shafts.
  • Shaft Seal: Butterfly valves may have a shaft seal to prevent leakage along the valve stem. This seal can be made of materials like elastomers or PTFE.
  • Driving System: In manual butterfly valves, the driving system involves a handle or lever that the operator uses to manually open or close the valve. In automated valves, a driving system such as an electric, pneumatic, or hydraulic actuator is used to control the valve remotely.

If you’re looking for specific information about these components in relation to a valve, it’s important to consult the manufacturer’s documentation or specifications for the particular valve model you’re interested in.
