Butterfly Valves are utilized in powder or liquid handling applications to isolate or regulate the circulate product. The closing mechanism is a disk that rotates, thereby permitting or stopping the stream of fabric. The “butterfly” is a steel disc (stainless steel available) mounted on a rod. When the valve is closed, the disc is turned in order that it fully blocks off the passageway. When the valve is fully open, the disc is rotated a quarter flip so that it permits an virtually unrestricted passage of the product or liquid. Bray Butterfly Valves are ideal for unloading and discharging materials from containers, hoppers or silos containing supplies in powder or granular in powder dealing with applications. Carolina Material Applied sciences gives 14 different models of the Butterfly Gate wafer check valve, together with butterfly valves that could be opened incrementally to permit throttle move. There are three fundamental categories: Resilient Seated, Double Offset, and Triple Offset.
