Bubble‑Tight Shutoff
VF Series Standard‑Pressure, Standard‑Temperature Butterfly Valves are specifically designed for a wide range of 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 rated pressure. These valves are also bidirectional, allowing positive shutoff with the flow in either direction. Two‑way configurations are available in sizes from 2 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 for 2 through 12 in. valves, 150 psig for 14 through 20 in. valves, and 50 psig for 4 through 20 in. valves.
