PROFILE
Velan is one of the world's leading manufacturers of industrial
valves, supplying forged and cast steel gate, globe, check, ball,
butterfly and knife gate valves for critical applications in the
chemical, petrochemical, oil and gas, fossil and nuclear power,
cogeneration, pulp and paper and cryogenic industries.
Founded in 1950, Velan earned a reputation for excellence as
a major supplier of forged valves for nuclear power plants and
the U.S. Navy. Velan Inc., pioneered many designs which
became industry standards, including bellows seal valves, all
stainless steel knife gate valves and forged valves up to 24".
Velan valves are manufactured in 12 specialized plants,
including five in Canada, two in Korea and one each in the
U.S., France, U.K., Portugal and Taiwan. We have a total of
1,091 employees in North America and 384 overseas.

VELAN MEMORY SEAL BALL VALVE TECHNOLOGY
Velan concave-convex
flexible “in-tension” seats

IN-TENSION
SEALING MEMORY
LOWER TORQUES
The Velan sealing memory is induced into the seats
during the assembly process. When the ball is
inserted into the valve body during assembly, it
partially flattens the seat, creating a tensile stress in
the center of the seat.
As a result, the seat core increases in diameter
from D1 to D2 and like a stretched elastic band
pushes against the ball. This ensures reliable
sealing even at vacuum or low pressures.
Velan “in-tension” seats produce more uniform
torque because the seat deflects into the cavity
behind it to accommodate slight differences in
machining tolerances or the normal expansion of
PTFE as temperature increases. PTFE expands
approximately seven times as much as metal.
SUMMARY OF MEMORY
SEAL BENEFITS
SEAT STRENGTH
A seat in tension is stronger than a seat in
compression because the tensile strength of PTFE
in tension is 3600 psi versus only 1800 psi for PTFE
in compression. Greater strength means less fatigue,
superior sealing ability and longer cycle life.
●
SEATS ”IN-TENSION“
- Greater strength
- Less fatigue
CAVITY PRESSURE RELIEF
- Positive bi-directional shutoff
Memory seal seats are designed to relieve
overpressure in the ball/body cavity. This capability
is influenced by many variables including: fluid
characteristics, variations in pressure, seat
materials, seat compression, temperature and
thermal cycles.
Positive release of cavity overpressure to the
upstream side is assured in bypassing the upstream
seat through a drilled hole in the ball. This option is
preferred in certain services such as liquid chlorine.
- Compensate for temperature fluctuations
- Uniform torque
- High cycle life
- Eliminate cold flow effects
●
LARGER SEATING AREA
- Superior sealing

2 Stem can wobble, cause leakage.
3 In lab tests 0 ppm emissions to 100,000 cycles,
500,000 with live-loading.
3 Larger emissions, lower cycle life.
4 Welding can affect the integrity of the valve
due to tendency to separate the three-bolted
body parts during the welding.
4 Easy to weld the one-piece body into the line
without disassembly. The integrity of the valve is
not affected.
5 Valve can not be serviced in-line, because of the
fire safe design with spiral wound gaskets which
requires internal guiding of the two end pieces.
The guiding prevents the centerpiece to swing out.
5 All parts can be easily serviced or replaced in-line.

wobbling and packing leakage
due to side thrust on stem.
2. Two piece flanged
gland design
for low fugitive emissions and
severe service applications.
3. Low emission stem seal.
Precompressed (2000 psi)
solid PTFE packing rings,
a two-piece flanged gland
and fine finish of stem and
I.D. of packing chamber
provides 0-20 ppm tightness
for low emissions.
4. Stem thrust washer
prevents galling, reduces

QUALIFICATION TESTED FOR
“0” PPM EMISSIONS
TEST PROCEDURE
The purpose of cycle testing was to determine
cycle life for 0 ppm tightness of stem seal and
body gasket with propane at 115 psi, 740 psi
and 1400 psi.
The testing consists of:
● Precycling evaluation.
● Gland
and body gasket emissions measured
every 500 cycles.
● Tested to 100,000 cycles; 500,000 cycles with
live-loaded packing.
TEST RESULTS
0 ppm tightness during tests shown on the
right. Definition of 0 ppm is no detectable
leakage registered on our organic vapor
analyzer which has a range of 1–10,000 ppm.
Top-entry, TE-600 with live-loading cycled for 500,000 with
0 ppm emissions.

CHLORINE SERVICE
Chlorine is extremely corrosive and toxic. Corrosion increases with the percentage of water moisture. Up to
50 parts per million or 0.005% water, chlorine is considered dry. Above this level, it is wet. The liquid gas
curve of chlorine is shown in the diagram below. There is also danger due to a high coefficient of thermal
expansion. When cold liquid chlorine is
trapped in the non-expanding space
1000
of the ball valve cavity, high destructive
70
pressures can develop.

Please see page 7 for material selection.
3. CLEANING
All parts are carefully cleaned and are
black light tested to assure they are free of
hydrocarbons, alcohol or moisture. Valves
are dried after hydrotest and packed in

CALCULATION OF THE ACTUATOR TORQUE REQUIREMENT
When determining the required actuator torque, seat material, fluid and frequency of
operation should be considered according to experience and judgement. For actual
required torques, for your application or valve automation, contact Velan or the
authorized Velan automation center of your choice.
Velan is not responsible directly nor indirectly for actuator selection by third parties.
14
STEM PACKING DESIGN
FOR AUTOMATION AND CONTROL
The higher cycle rates resulting
from the automation of ball valves
for either remote operations or
throttling control requires superior
stem packing designs. The Velan
stem packing design as well as
the optional designs shown on
page 4 are intended for automated
valve service.
The integrity of these designs has been
verified by our own laboratory testing,
operating experience and in qualification tests by inspection agencies.
This assures trouble free service in
automated and throttling control and
the best in stem packing integrity.
