Honeywell VGF3 Three-way Flanged Globe Valves


VGF Flanged Globe Valves are used for 2-position or modulating control of steam, hot water, or chilled water-glycol solutions up to 50% 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 valve linkage. Threeway bodies are available in mixing or diverting style with equal percentage and linear flow characteristics. Pressure-balanced models feature very high, low leakage close-off ratings.
• 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.
• Metal-to-metal seating for long life span.
• Stainless steel trim standard.
• Differential pressure of 175 psi, ANSI Class IV on pressure-balanced models.
• Steam inlet pressure up to 125 psig.
• Self-adjusting packing.
• Accurate positioning with equal percentage and linear flow characteristics to ensure state-of-the-art 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.
• Linear (constant total) flow throughout full plug travel (3-way diverting models).
• Not suitable for combustible gasses.
