VGF Flanged Globe Valves
APPLICATION
VGF Flanged Globe Valves are used for 2-position or
modulating control of steam, hot water, or chilled water in
closed loop HVAC systems. They can be operated by a
large variety of electric and pneumatic actuators. Three-
way valves are available in mixing or diverting flow
patterns.
FEATURES
• ANSI Class 125 and Class 250 flanged cast iron
bodies.
• Face-to-face flange dimensions per ANSI/ISA S75.03
standard.
• Sizes from 2-1/2 to 6 inches (DN65 to DN150).
• Metal-to-metal seating for long life span.
• Differential pressure of 175 psi, ANSI Class IV
leakage on pressure-balanced models.
• Steam inlet pressure up to 100 psig (689 kPa).
• Self-adjusting packing.
• Equal percentage and linear flow characteristics to
ensure precise control in a variety of applications.

IMPORTANT
Valve sizing is important for correct system opera-
tion. Undersized valves do not have sufficient
capacity at maximum load. Oversized valves do not
have sufficient authority over the load in modulat-
ing applications.
Oversized valves can initiate hunting and the seat
and throttling plug can be damaged because of
the restricted opening. Some variables that must
be determined are:
•Medium (steam, water, glycol solution 50 percent
maximum) to be controlled.
•Maximum temperature and pressure of the
medium at the valve.
•Pressure differential that exists across the valve
under maximum load conditions.
•Maximum capacity the valve must deliver.
•Maximum line pressure differential against which
the valve actuator must close.
