Flanged Valves

APPLICATION

VGF Flanged Globe Valves are used for 2-position or

modulating control of steam, hot water, or chilled water-glycol

solutions up to 50% concentration in heating, ventilation and

air conditioning (HVAC) systems. They can be operated by

ML6984/7984, ML6420/6425, ML6421/7421 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 characteristics. Pressure-balanced models

feature very high, low leakage close-off ratings.

FEATURES

• ANSI Class 125 and Class 250 cast iron bodies with

flanged end connections.

• Face-to-face flange dimensions per ANSI/ISA S75.03

standard.

• Sizes from 2-1/2 to 6 inches.

• Metal-to-metal seating for long life span.

• Stainless steel trim standard.

• Differential pressure of 175 psi, ANSI Class IV on

pressure-balanced models.

• Steam inlet pressure up to 100 psig.

• Self-adjusting packing.

• Accurate positioning with equal percentage and linear

flow characteristics to ensure state-of-the-art

temperature control.

• Universal bonnet for direct-coupled electric and

pneumatic actuators for easy mounting, or linkage-

coupled Modutrol® Motors and MN/MS Series direct-

coupled actuators.

• Constant total flow throughout full plug travel (3-way

diverting models).

• Not suitable for combustible gasses.

VGF FLANGED VALVES SERVICE General Fig. 20 shows the valve in the fully open or fully flowing position from the B port to the AB port. As the valve stem moves downward, the flow from the B to AB ports decreases and the flow from the A to AB ports increases. As the valve stem moves upward, the flow from the B to AB ports increases and the flow from the A to AB ports decreases.
