A wafer butterfly valve is a type of quarter-turn valve that regulates the flow of fluids in a pipeline. It's called a "wafer" valve due to its slim, wafer-like profile, allowing it to be installed between two flanges without the need for additional flange bolts.
The valve consists of a disc or "butterfly" that rotates around a central shaft. This disc is typically made of metal or a resilient material such as rubber or PTFE. The valve body features a slim profile, facilitating easy installation between flanges.
Open Position: The valve disc rotates parallel to the flow direction, allowing fluid to pass through with minimal obstruction. The disc is mounted centrally and supported by a shaft.
Flow Control: The valve disc is rotated using an actuator (manual, electric, pneumatic, or hydraulic). As the disc rotates, it gradually obstructs the flow to reduce the flow rate.
