VF Series High-Pressure,
High-Temperature Butterfly Valve Assemblies
VF Series High-Press ur e, High-T e mp er ature But ter fly
Valve Assemblies are specifically designed for a wide
range of Heating, Ventilating, and Air Conditioning
(HVAC) applications including two-position and
modulating/throttling control of hot water, chilled water,
condenser water, and steam. Refer to the VF Ser i es
High-Pressure, High-Temperature Butter f l y Valves for
Steam Service Application Note (LIT-977321) for more
information on steam app lic atio ns . T hese lu g-style
valves offer bidirectional shutoff at fully rated American
National Standards Institute (ANSI) Class 150 and 300
operating pressures, increasing the range of
applications – particularly in high-rise building HVAC
control applications. ANSI Class 150 and 300 models
are also suitable for steam applications.
ANSI Class 150 Butterfly Valves are avai lab le in
two-way configurations, in sizes ranging from
2-1/2 through 16 in. ANSI Class 300 Butterfly Valves
are available in two-way configurations , in sizes
ranging from 2-1/2 through 14 in. ANSI Class 150
valves are rated for 240 psig at 250°F, and ANSI
Class 300 valves are rated for 550 psig at 250°F.

VF Series High-Press ur e, High-Temperature Butterfly
Valves provide the highest quality and best value
available in the HVAC control industry. These valves
are recognized as a proven leader, with more than
25 years of successful service in process industries
worldwide. Their unique, patented design has received
Chemical Processing’s Valor Award for Best Product.
The simple, innovative design of these valves provides
rugged reliability and extremely easy maintenance in
the field. Independent and internal tests have proven
their superior service life capability, with bubble-tight
shutoff through over 100,000 cycles.
VF Series High-Pr ess ur e, High-Temperature Butterfly
Valves can be automated inexpensively with
pneumatic and electric actuators.
When compared to gate, globe, ball, and plug valves,
VF Series High-Press ur e, High-Temperature Butterfly
Valves are significantly smaller and lighter in weight;
therefore, installation time and maintenance costs are
greatly reduced.
All VF Series High-Pressure, High-Temperature
Butterfly Valves are available with a factory-assembled
and calibrated actuator, sized with a 25% safety factor
to provide years of trouble-free operation. The wide
variety of actuator choices include high-pressure
pneumatic rack and pinion-style actuators (both spring
return and non-spring return), and high-torque rotary
electric actuators which are fully compatible with
®
Metasys
controllers. The valve and actuator can be
provided in Normally Open (N.O.) or Normally
Closed (N.C.) combinations for pneumatic two-way
operation.
Stem
The one-piece stem is constructed of high strength
17-4 PH stainless steel. The output shaft of the stem is
extended to provide a direct connection of the actuator
to the valve.
Disc
The disc is constructed of 316 stainless steel, and is
engineered to maximize flow. The double offset design
of the stem reduces seat wear to significantly extend
cycle life. Bidirectional bubble-tight shutoff is assured
throughout the full pressure range.
Taper Pins
The taper pins are precision fit into drilled,
taper-reamed holes, providing a positive connection
and maximum strength between the valve disc and
stem.
Internal Travel Stop
An internal travel stop is designed to prevent
overtravel of the disc, minimizing possible seat
damage.
Valve Body
The ANSI Class 150 lug-style valve body is carbon
steel, and meets the pressure and temperature
requirements for ANSI B16.5, Class 150 pipe flanges.
The ANSI Class 300 lug-style valve body is carbon
steel, and meets the pressure and temperature
requirements for ANSI B16.5, Class 300 pipe flanges.

Extended Neck
The extended neck allows for 2 in. (51 mm) of pipeline

Adjustable Stem Packing
The stem packing system features easy access to
adjusting hex-head nuts wit hout re qu irin g removal of
the actuator. The stem consists of a gland ring, a
gland retainer, studs, hex-head nuts, and lock
washers. A slight 1/4 turn of the hex-head nuts is
usually all that is required should field adjustment ever
be needed. Both hex-head nuts must be evenly
adjusted, and not over tightened.
Figure 7: Adjustable Stem Packing System
Stem Seal
A positive seal is formed around the stem by the
constant compression and excellent corrosion
resistance of the stem seal. PTFE packing rings seal
the stem, and a carbon fiber anti-extrusion ring retains
the packing.
Seat Design
The unique, live-loaded seat consists of a resilient
silicone O-ring energizer that is fully encased by the
reinforced polytetrafluoroethylene (RPTFE) seat. The
seat is locked into the valve body recess by a
full-faced seat retainer plate. This simple, reliable, and
proven combination provides many exclusive
advantages including:
•The O-ring energizer is completely isolated from
all contact with the line media by the RPTFE seat.
•Serrations in the seat retainer plate and body
recess secure the seat in place. The full-faced
retainer plate is bolted to the body, locking the
seat in the correct position. The seat is secured
even without the mating flange.
•The closely confined and well supported seat is
energized by the disc and line pressure. The
higher the pressure, the tighter the seal. In low
pressure applications, the energized seat offers
superior sealing and longer service life than many
other designs.
•Line media is sealed bubble-tight in both
directions.
•The live-loaded seat is self adjusting for wear and
temperature fluctuations.
•Seat replacement is extremely easy – just remove
the seat retainer plate, rotate the disc into the
closed position, and place a new seat in the
machined recess of the body. Performing this
procedure does not disturb the disc or stem.
All ANSI Class 150 and 2-1/2 through 12 in.
ANSI Class 300 valves feature one set of stem seal
packing rings and a stem locating plug with an O-ring
seal in the body base. The 14 in. ANSI Class 300
valves feature upper and base twin stem seals that
balance axial forces on the stem and disc under all
operating conditions.
Stem Bearings
Top and bottom bearings, consisting of a
316 stainless steel shell with a TFE/glass fabric liner
bearing surface, securely support the stem. The stem
bearings provide excellent resistance to corrosion and
distortion from high temperatures and mechanical
loading forces.
