Description
VF Series Standard-Pressure, Standard-Temperature Butterfly Valves are specifically designed for a wide range of Heating, Ventilating, and Air Conditioning (HVAC) applications, including two-position and modulating control of hot, chilled, or condenser water, and 50/50 glycol solutions. All valves are factory tested for bubble-tight shutoff at 100% of the fully ratedpressure. These valves are also bidirectional, allowing positive shutoff with the flow in either direction.Two-way configurations are available in sizes from2 through 20 in. Three-way assemblies have two valves that are linked together and mounted on a flanged, cast-iron tee. Three-way configurations are available in sizes from 2 through 12 in. Standard pressure valve ratings available include 175 psig for2 through 12 in. valves, 150 psig for 14 through 20 in. valves, and 50 psig for 4 through 20 in. valves.
