Butterfly Valve Design & Construction
A butterfly valve consists primarily of a valve body, disc, stem and sealing arrangement. The disc rotates around the stem axis to control the flow passage through the pipeline.
Valve Body
The valve body houses the disc and sealing components and connects the valve to the piping system. Body material selection depends on pressure, temperature and fluid compatibility.
Disc
The disc is the primary flow-control component. It rotates within the valve body to open, close or regulate the flow passage.
Stem
The stem transfers operating torque from the handle, gearbox or actuator to the valve disc.
Seat
The valve seat provides sealing between the disc and body when the valve is closed. Seat material should be selected according to the operating medium and temperature.
Actuator
Butterfly valves may be operated using a manual lever or gearbox. Pneumatic and electric actuators can be used for automated operation.
