Wafer style butterfly valves are quarter-turn valves used to allow, prohibit, or regulate the flow of fluids. They have a disc that is turned parallel or perpendicular to the flow by a rod that may be connected to an actuator. Furthermore, they are designed to prevent backflow by maintaining a seal against bi-directional flow. Wafer style butterfly valves are generally preferred over other valves due to their lightweight design and cheaper price.
