Flanged Globe Valve

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.
