Flanged Globe Valves
VGF3 Three-way Flanged Globe Valves
VGF Flanged Globe Valves are used for 2-position or modulating control of hot water or chilled water-glycol solutions up to 50% concentration in closed loop heating, ventilation and air conditioning (HVAC) systems. They can be operated by ML6984/ 7984, ML6420/6425, ML6421/7421 Electric Linear Actuators, MP953
Dimensions in inches (millimeters)
Pneumatic Actuators, Modutrol™ Motors with Q5001 valve linkage, or MN/MS Series Direct Coupled Actuators with Q5020 or Q5022 valve linkages. Three-way bodies are available in mixing or diverting style with equal percentage and linear flow characteristics, respectively. For boiler/chiller bypass applications requiring tight close-off, use VGF31/32LD diverting valves. For outdoor temperature compensation of building supply water, or modulating control of heat exchangers, use VGF31/32EM mixing valves.
•ANSI Class 125 and Class 250 cast iron bodies with flanged end connections
•Face-to-face flange dimensions per ANSI/ISA S75.03 standard
•Sizes from 2-1/2 to 6 inches
•Stainless steel trim standard for long life span
•Self-adjusting packing
•Accurate positioning with equal percentage and linear flow characteristics to ensure precise temperature control
•Universal bonnet for direct-coupled electric and pneumatic actuators for easy mounting, or linkage coupled Modutrol™ Motors and MN/MS Series direct coupled actuators
•Constant total flow throughout full plug travel (3-way diverting models)
•Not suitable for combustible gasses
