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.
