VGF
Flanged Globe Valves
APPLICATION
VGF Flanged Globe Valves are used for on-off or
modulating control of steam, hot water, or chilled water-
glycol solutions up to 50% concentration in heating,
ventilating and air conditioning (HVAC) systems. They
can be operated by ML6984/7984, ML6420/6425,
ML7420/7425, M6421/7421 Electric Linear Actuators,
MP953 Pneumatic Actuators, Modutrol® Motors with
Q5001 valve linkage, or MN/MS series Direct Coupled
Actuators with Q5020 valve linkage.
Three-way bodies are available in mixing or diverting
style with equal percentage and linear flow characteristic.
Pressure-balanced models feature very high, low
leakage close-off ratings. Flanges conform to ANSI
standard B16.1, Classes 125 and 250, with face-to-face
dimensions per ANSI/ISA 75.03

Safety
The valves are to be installed by skilled personnel and in
strict accordance with the installation instructions and
local regulations. (See Fig. 1 for proper hoisting method.)
Honeywell assumes no responsibility for damages or
injuries resulting from non-compliance with installation
instructions or standard good practice when mounting,
operating, or maintaining the valves, even if not explicitly
mentioned in the installation instructions. (See Fig. 2 for
basic pipe orientation.) Observe all safety practices when
working with steam systems.
Proper Use
These valves are only for use in cold, warm, hot water
systems and for steam applications. They are designed
for a medium temperature range of from 35 to 355°F, at a
maximum pressure of 125 or 250 psig, depending on
their ANSI body class. They are to be operated with the
appropriate Honeywell actuators only. Please refer to the
VGF family product data sheet, form 63-2618 for detail.
Water should be properly filtered, treated and
conditioned according to local conditions. The installation
of a strainer is strongly recommended.
