Honeywell VGF31EM50 5″ Flanged Mixing Valve, ANSI 125, Cv=250, Equal %

Description

Honeywell VGF31EM50 5″ Flanged Mixing Valve Overview

The Honeywell VGF31EM50 is a heavy-duty, 5-inch flanged three-way mixing valve engineered for demanding commercial and industrial HVAC hydronic applications. With an ANSI 125 flange rating and a high flow coefficient of Cv=250, this valve is designed to handle large-volume water flow with precision and reliability. Its equal percentage flow characteristic ensures smooth, stable control across the full range of valve travel — making it an ideal choice for variable flow systems where accurate temperature regulation is critical.
