VGF3
VGF Flanged Globe Valves are
used for 2-position or modulating
control of hot water or chilled water-
glycol solutions up to 50 percent
concentration in heating, ventilation
and air conditioning (HVAC)
systems. They can be operated by
ML6984/7984, ML6420/6425,
ML6421/7421 Electric Linear
Actuators, MP953 Pneumatic
Actuators, Modutrol™ Motors with
Q5001 valve linkage, or MN/MS
Series Direct Coupled Actuators with Q5020/Q5022 valve
linkages. Three-way bodies are available in mixing or diverting
style with equal percentage and linear flow characteristics,
respectively.
