VG2000 Series Cast Iron Flanged Globe Valves for Assembly in the Field
Description
VG2000 Series Cast Iron Flanged Globe
Valves are designed primarily to regulate the
flow of water and steam in response to the
demand of a controller in HVAC systems.
Available in sizes 2-1/2 through 6 in., these
ANSI Class 125 valves are available in
Normally Open (N.O.), Normally Closed
(N.C.), and three-way mixing configurations.
Both electric and pneumatic actuators are
available for factory or field mounting.
Refer to the VG2000 Series Cast Iron Flanged
Globe Valves Product Bulletin (LIT-977133)
for important product application information.
