Honeywell VGF31EM40 Flanged Globe Mixing Valve

The Honeywell VGF Flanged Globe Valves provide precise 2-position or modulating control of hot water or chilled water-glycol solutions up to 50% concentration for HVAC systems. These versatile valves are compatible with a range of actuators, including ML6984/7984, ML6420/6425, ML6421/7421 Electric Linear Actuators, MP953 Pneumatic Actuators, and Modutrol Motors with Q5001 valve linkages, as well as MN/MS Series Direct Coupled Actuators with Q5020 or Q5022 linkages. They come in three-way mixing or diverting styles with equal percentage and linear flow characteristics. For applications requiring tight close-off, such as boiler/chiller bypasses, the VGF31/32LD diverting valves are recommended. The VGF31/32EM mixing valves are ideal for outdoor temperature compensation of building supply water and heat exchanger modulation.
