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.

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.
