Pneumatic Butterfly Valve

These Butterfly Valves have naturally high pressure-recovery factor, which is used to predict the pressure recovery occurring between the vena contract and the outlet of the valve. The valves ability to recover from the pressure drop is influenced by the geometry of the wafer-style body, the maximum flow capacity of the valve, and the service's ability to cavities or chokes. Because of the high pressure recovery, Butterfly Valves work exceptionally well with low-pressure drop applications. The material construction of the valve is SS304, 304L, 316 & 316L.
