VF Series High-Pressure, High-Temperature Butterfly
Valve Assemblies are specifically designed for a wide
range of Heating, Ventilating, and Air Conditioning
(HVAC) applications including two-position and
modulating/throttling control of hot water, chilled water,
condenser water, and steam. Refer to the VF Series
High-Pressure, High-Temperature Butterfly Valves for
Steam Service Application Note (LIT-977321) for more
information on steam applications. These lug-style
valves offer bidirectional shutoff at fully rated American
National Standards Institute (ANSI) Class 150 and 300
operating pressures, increasing the range of
applications – particularly in high-rise building HVAC
control applications. ANSI Class 150 and 300 models
are also suitable for steam applications.
ANSI Class 150 Butterfly Valves are available in
two-way configurations, in sizes ranging from
2-1/2 through 16 in. ANSI Class 300 Butterfly Valves
are available in two-way configurations, in sizes
ranging from 2-1/2 through 14 in. ANSI Class 150
valves are rated for 240 psig at 250°F, and ANSI
Class 300 valves are rated for 550 psig at 250°F.
