PRODUCT DATA
FEATURES
VGF22
VGF21
• 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.
VGF32
VGF31
• 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.
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.
• Universal bonnet for direct-coupled electric and
pneumatic actuators for easy mounting, or linkagecoupled Modutrol® Motors and MN/MS Series directcoupled actuators.
• Constant total flow throughout full plug travel (3-way
diverting models).
• Not suitable for combustible gasses.

IMPORTANT
Valve sizing is important for correct system operation. Undersized valves do not have sufficient capacity at maximum
load. Oversized valves do not have sufficient authority over the load in modulating applications.
Oversized valves can initiate cycling 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.

INSTALLATION
When Installing this Product...
1.
2.
3.
4.
Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
Check ratings given in instructions and on the product to
ensure the product is suitable for your application.
Installer must be a trained, experienced service
technician.
After installation is complete, check out product
operation as provided in these instructions.
WARNING
Severe Burn Hazard.
Contact with hot liquid can lead to severe injury or
cause death.
Release system pressure and isolate or drain the
valve pipe section so the medium (steam, water or
glycol solution) does not leak out of the valve body
during installation (see Fig. 9).
installation instructions. (See Fig. 10 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. Water should be
properly filtered, treated and conditioned according to local
conditions. The installation of a strainer is strongly
recommended.
IMPORTANT
The presence of iron oxide (red rust) in the system
voids the valve warranty.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect power supply to the actuator to prevent
electrical shock and equipment damage, or remove
and cap the air line to the actuator.
IMPORTANT
• Before installing the valve, raise and lower the valve
stem to make sure that the valve stem operates
freely. Impaired stem operation can indicate that the
stem was bent by rough handling. This condition can
require replacing the valve.
• Protect the stem from damage due to bending or
scratching.
M22590

Safety
The valves are to be installed by skilled personnel and in strict
accordance with the installation instructions and local
regulations. (See Fig. 8 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

COMPANION
FLANGE
6.
7.
BE SURE FACE OF COMPANION FLANGE IS FLUSH
WITH FACE OF VALVE-BODY FLANGE AND ALIGNED
SQUARELY BEFORE TIGHTENING MOUNTING NUTS.
Hoist valve by its body only. Do not lift by stem, bonnet,
flanges, or flange holes. (See Fig. 8.)
Install the valve so the flow follows the direction of the
arrow indicated on the valve body.
Install the valve so the actuator is above the valve body.
The valve can be installed in any position between vertical and horizontal. Do not install the valve with the stem
below horizontal or upside down.
When controlling steam, use appropriate high
temperature kit 43196000 and rotate valve body so that
actuator is not positioned directly above the piping.
Use companion flanges with the same number of bolt
holes and dimensions as the valve to be installed. The
optional service flange may be installed in the lower
port. See Table 1 for part numbers. Use standard castiron flanges for the two end ports.
Use a gasket material recommended for the medium to
be handled.
Use mounting bolts long enough so the nuts can use the
full length of the nut threads. (See Fig. 11.) Use bolts
1/8 in. smaller than the diameter of the bolt hole to allow
clearance for installing. (See Fig. 12.)

For information on mounting, refer to the Product Data

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.
For electric control, a spring return actuator returns the valve
to its normal position (open or closed to the A or the B port,
depending on the actuator selected) in the event of a power
failure. Non-spring return actuators hold the last commanded
position.
For pneumatic control, the actuator returns the valve to its
normal position (open or closed to the A or the B port,
depending on the actuator selected) in the event of a loss of
control air pressure.
For typical flow curves see Fig. 1 and 2.
