Description
Honeywell VGF31LD40 4″ Flanged Diverting Valve Overview
The Honeywell VGF31LD40 is a heavy-duty 4-inch flanged, three-way diverting valve engineered for precise flow control in commercial and industrial HVAC hydronic systems. With an ANSI Class 125 pressure rating and a high flow coefficient of Cv=160, this valve is designed to handle demanding applications where accurate water or glycol distribution is critical. The linear flow characteristic ensures a proportional relationship between valve stroke and flow rate, making it an ideal match for modulating actuators in building automation and hydronic control systems.
