Solution # 1 M series triple offset valve (FIGS. 1,2)
The M Series triple offset butterfly valve is the solution
with the following unique features through full scope analysis
(1) The most optimized triple offset design model is created to
reduce the real interference or engaged angles to max 0.10
degree B through 0-90 ° rotation
(2) Wave seat , 100 % metal seat is invented to meet graphite
free seal challenge, it can stand for temperature -425 to 1800
F° and thermal delta over 900 F° without leakage and
replacement during service.
(3) K ring stem packing , 100 % metal seal is invented to meet
graphite free seal challenge, it can stand for temperature -425
to 1800 F° and thermal delta over 900 F° without
replacement during service, the stem leakage level is less
than 50 PPM.
(4) Bolt/keyless locking system for vibration up to 120 g’s
Challenge # 2 Reality vs. Theory
Over 99 % of triple offset butterfly valves in the world
never pass the bidirectional cryogenic test , low pressure air test
or stringent customer fire test , over 98% of triple butterfly
valves in the world have interferences between disc seat and seal
ring through 0.25 to 6 ° rotation , so the benefit of no rubbing or
interfering for the triple offset geometry is never applied to most
of the triple offset valves.

FIG. 2
Solution # 2 M series butterfly valve (FIGS. 1,2)
There are two triple offset myths (1) the triple offset
guarantees a good metal to metal seal, in reality it only resolves
the interference issue between seat and seal ring through 0-90 °
rotation and does not guarantees a good metal seal (2) every
triple offset design guarantees zero interference angle through 090 ° rotation , in reality, no triple offset valve has zero
interference due to machining tolerance or poor design among the
parts. The test data indicate the interferences or engaged angles
less than 0.25 ° have no significant effect on the life of seat , so in
short the triple offset design is an art rather than a science for
most triple offset valve makers.
The interference angle (B° ) for M series valve is less than
0.10 degrees which stabilize the seal and obtained by using (I) a
proprietary design model to optimize four variables ; X, Y, A , a
tilt angle not shown (II) a proprietary manufacturing process.

Challenge # 3 Solid seat vs. laminated graphite seat
Most triple offset valves have one laminated graphite seat eight on
the body or disc, the laminated seat is an evolution from solid seats
developed in 1960s, the solid seat was so rigid and subject to very high
torque for operation and can not meet ANSI FCI 70-2 Class VI and is
required with expensive mating process, today it is only used for high
temperature applications where the graphite can be carbonized, but it still
can not resolve the carbonizing issue, because the gasket behind the solid
seat is made out of graphite, the laminated seats are made out of metal
rings glued with graphite and are less rigid , but still subject to high
torque for operation, the glued graphite is fragile and cannot sustain high
surface contact stress, erosion or high temperature, the metal layer of the
laminated seat next to the gasket prevents back leak, if the layer fails to
seal, the whole seat will leak , the seat is neither self-compensated nor
self-healed, so the constant replacement is required and very expensive.
Solution # 3 Full metal wave seat (FIGS. 3,4,5)
M series valve is equipped with novel wave seats to overcome the
difficulties of both solid seat and laminated seat
(1) Material . The metal wave seat is fabricated through a proprietary
process and is much stronger but flexible as a spring without graphite and
the glue used on the laminated seat , so it breaks (a) the temperature
barrier of 850 F , specially in jet or rocket engine and turbine applications
where it is used for throttling high temperature, highly oxidative flows
(b) increase life of the wave seat by 5 to 100 times in comparison with the
laminated or solid seat (c) increase sealability for extreme severe services
(2) Sealing design. Each wave seat is constructed with a pair of a
balanced, inward to and outward conical seal surfaces in order to
eliminate any side seal gasket and self-compensate for any radial and axial
gap between the seat and body seat and establish a robust seal, the wave
seat acts as a reverse disc spring to stores and releases torsion energy
during operation unlike the laminated or sold seat with one side seal
which act as an energy dissipater , the benefits are (a) to reduces the
torque and wearing by 30 to 60% (b) increase life of the wave seat by 5
to 100 times (c) build a robust seal even under 120 g’s vibration.
(3) Performance . Reliability (a) each wave seat acts independently
without side seal, so only the wave seats can be constructed with double ,
triple redundancy, while the laminated seat only has one seal (b) the wave
seat seal has 3 parts ; disc, wave seat and body seat ,while the laminated
seat seal has 4 parts ;body seat, seat, disc and gasket . Durability, the
wave seat is self-compensated axially as well as radially and self-healed,
while the laminated seat cannot self-compensate , the wave seat takes
pressure load only at a closed position, while the laminated seat not only
takes pressure load at a closed position , but also constantly take side load
even at an open position where the seal is not required, so any open or
closed operation will generate heat and wear gasket due to side load and
side seal.
The valve with the wave seat is not only the most reliable and
durable over all existing triple offset butterfly valves , but also can
compete against conventional metal ball valve as well as gate valve at
high pressure /temperature services where the gate and ball valves still
struggle with the unsolvable rubbing problem . Finally the wave seats can
be installed on both the disc and body , so the replacement will be much
cheap and easy for high erosive flow applications , if ANSI FCI 70-2
class VI is required , the wave seat can maintain the class VI seal during
the service , the wave seats alone can last 5 to 60 years.

Challenge # 4 Graphite stem packing
All triple offset valves have graphite stem packings even in
high temperature application where the seat is sold without graphite, so
the integrality of the design is very questionable , the graphite packing
limits the applications for temperature 850 F° or over with oxidative
fluid , they are neither self-compensated nor self-healed, so the
replacement and repacking are constantly required . In some cases like
subsea , restrict area, constant repacking or replacements are impossible.
Solution # 4 K ring stem packings (FIG.6-9)
Metal K ring is an ultimate package for butterfly valve
dynamic stem seal under extreme conditions; high temperature 800-1800
F or high vibration to 120g’s, the fugitive emission level is 1– 50 PPM
during service, it is self-compensated and self-healed.
(1) K ring comprises a metal I ring and a metal V ring , it revolutionarily
changes the stem seal concept from a radial seal to an axial seal with
100% compression force, according to Hook law and Poisson’s
ratio , only 35 % axial force is converted to radial displacement to
seal the stem, so K ring packing is the most efficient stem seal.
(2) K ring is self energized with V ring as a pair of disc springs and
rotated with the stem to converts a radial, dynamic seal to a static seal.
(3) K ring is used for balancing the gland compression and stem/disc
weight with internal pressure force, so K ring packing can share the
weights of stem and disc with the seat and reduce the seat wearing due
the weights and stabilize the stem seal.
(4) K ring can prevent the stem from blowing up in case of break down.
(5) K ring stem packing also includes a pair of packings, the packing
can be metal G ring , metal or graphite laminated rings, so the seal
has five redundant barriers (1) low- packing (2) metal low -V ring
(3) sealant in V cavity (4) metal up-V ring (5) up-packing.

Solution # 6 Bolt/Keyless locking system (FIGS. 10-14)
M series Valve has a unique internal locking system with
three features for high temperature , high vibration, fracking fluid
and high frequency cycle between open and closed positions,
(1) Wedge lock rings ( up to 4 ) and eccentric lock plugs (up to 8)
are used for securing retain ring and the seat with the disc , the
wedge or conical surface of retain ring is engaged with wedge or
conical surfaces of three lock rings, the eccentric groove of the
lock plugs is engaged with the tips of the lock rings to tighten the
engagement by rotating the plug with eccentric groove, finally
the screw in the lock plug can be used for further tightening the
engagement between the lock ring and retain ring , since the
engaged angle between the lock ring and retain ring has self
locking function , the retain ring and lock ring and plug are
interlocked , the length of the screw is longer than the that of
operation slot , each locking device has different locking
direction , so there is no chance that the screw or lock plug to fall
out under any condition, beside the function of anti-loosing
function, the area cross section of lock rings are larger than a
that of bolting , less machining and uneven tightening , in short
the joint is the most reliable , robust and stable.
(2) Wedges and eccentric lock plugs are used for the joint between
stem and disc, the two wedge slots are located at the middle of
disc to receive respectively two wedges, the wedge surface of
wedge is engaged with wedge surfaces of stem , the eccentric
groove of the lock plug is engaged with a tongue of the wedge
to tighten the engagement by rotating the plug, the wedge , plugs
and stem are interlocked , there is no chance that the wedge or
plug to fall out under any condition , beside the anti-loosening
function, the wedge slots on the disc or stem are located at less
stress section and open up more space for the flow, such a joint
not only eliminates the clearance between disc and stem , but has
freedom to tolerate the thermal expansion between stem and disc .

Challenge # 6 Bolt /key/Pin internal locking system
All triple offset butterfly valves have the internal locking
system with (1) axial bolting to secure retain ring and seat with the
disc, the problem for the bolting is that under high temperature and
high vibration over 25 g’s like turbine or rocket engine or fracking
fluid operation, according to FMEA , the bolting structure has highest
severity, it tends to loosen and fall into the pipeline, it not only cause
leak ,but also damage downstream critical part such as turbine or
engine, moreover for large size 10” and up, the uneven tightening is
an other constant problem and causes leak and falling bolts, for high
temperature and vibration applications , even with anti-loose washer,
the bolts still tend to loosen and fall out (2) the key joint is used
between stem and disc for most triple offset valves, the problems for
key joint are to cause (a) X, Y direction clearances and leak on the
non preferred side (b) floating in Z direction and cause vibration and
damage the seat, so some valve makers have a solution to restrain the
Z movement with a lock pin, the problem with the pin is to
completely restrict free expansion in Z direction between disc and
stem and can damage the seat under high temperature or thermal
shock.

Design Features
due to the friction stop not mechanical hard stop , with K
ring support, the joint is the most reliable and robust and
stable.
(3) The spring bearing is constructed with a bearing and three
spring pins and installed in a stem hole to guide the stem ,
the three spring pins are installed in the bearing slots to
eliminate any clearance between the Bearing ID and the stem
OD, body bearing hole and bearing OD , while the stem is
rotated freely due to line contact, it not only eliminates the
clearance for preventing the vibration , but also is used for
high thermal shock applications, finally it has selfcompensated and self-healed for any wearing and can last 560 years or up to 1 million cycles without repairing and
replacement, there is no other bearing which can compete,
Challenge # 7 Unidirectional vs. Bidirectional
Most triple offset valve makers claim that their valves are
bidirectional seal, but the valves have a preferred side seal, in
fact either both sides of the valves cannot hold the same pressure
or the non-preferred side can hold pressure too low, or leak after
quick closed , so they are unidirectional seal.
Solution # 7 Bidirectional seal by design (FIGS.14-16)
The triple offset Butterfly valve has an inherent, single
seat structure and is either used for an upstream seal (nonpreferred , Flow B ) or a downstream seal ( preferred , Flow A ) ,
the reason for the deference is that both seat and seal ring are
radially flexible and axially fixed , so without rotating the disc ,
there is no an axial flexible mechanism to compensate for any
gap caused by (a) clearances between a stem and a bearing (b)
pressure forces, without special design , the bidirectional seal is
impossible. The solution includes (1) a spring bearing is
constructed with a bearing and three spring pins and installed in
a stem hole, the three spring pins are installed in the bearing slots
to eliminate any clearance between the Bearing ID and the stem
OD and self-compensated for any wearing , while the stem is
rotated freely due to line contact (2) the wave seat is radially and
axially flexible to self-compensated for any gap caused by flow B
pressure without rotating the disc, as the disc tends to move
away from the body seat under flow B , the wave seat tends to
return to the original shape to fill any gap between the body seat
and the wave seat ,when the valve is under flow A pressure , the
wave seat tends to smash the body seat , sometime it can damage
the seats, but the spring bearing and the wave seat can damp the
impact force, moreover they can be used in high temperature
application to sustain thermal shock or compensate for any
deformation under high pressures. Finally the spring bearing and
the stem are self –healed and can last for 5-60 years service
without repacking ,repairing and replacement.

Challenge # 8 On-off vs. Throttling
The triple offset butterfly valves are mainly used for on-off ,
some of them are used for throttling, the useful range is between 1575 degree , but the erosion and cavitation mainly happen between 045 degree rotation and cause the seat or disc or even body
prematurely damage , some trims are applied to disc, but the
improvement is very limited and replacement or manufacturing for
the trims are very expensive, while trims are applied to the body, in
most cases the valves have one downstream trim which is not very
effective, the trims reduce the flow rate capacity by 50 % or more.

Challenge # 9 Inline repairable valve
Most inline repairable butterfly valve can not stand for high
vibration up to 25g’s or without redundant body seal.
Challenge # 10 Full port vs. obstructed port
Ball valve and gate valve are full port valve without any
obstruction at full open position, the full port valve must be used
when solid object have to pass through the valve or high flow rate is
required , but they are expensive and larger, while all butterfly valve
have an obstructive port and are compact and lighter , but cannot be
used for full port applications or high flow applications.
Solution # 10 M series Triple offset ball valve (FIG. 19)
M series valve with a triple offset ball takes the triple offset
mechanism to the next level, the valve not only have all ball valve
benefits, but also have no rubbing advantage and redundant positive
seals over all metal seal ball valve as well gate valve to meet full
port requirement or to replace the ball valve or gate valve with the
same flow requirement .
(a) a replacement for all orbit ball valve, the reasons are (1) No
rising stem with easy automation and less stem leak (2)
redundant seal (3) bidirectional seal (4) field /inline repairable
(b) A replacement for ball valve/ gate valve applications with
requirements of the reliability (0.2-1 million cycles )and
durability (5- 60 years) without leak, repacking, repairing and
replacement .

Solution # 8 A pair of partial trims ( FIG.17)
M series valve with a pair of partial trims can be used for both
on-off and throttling at the same time , the inlet flow is divided to a
left stream and right stream, the left stream goes through the down
stream trim to gradually reduce the pressure drop, while the right
stream goes through the up-stream trim to gradually reduce the
pressure drop, the trims reduce cavitation by 50 % and noise level
to below 80 dB, while the capacity is only reduced by 25 % , the
trim is easily secured by a lock ring in installed a groove between the
body and trim or step bore and position pin.
Solution # 9 M series valve (FIG. 18 )
M series valve with the inline repairable body can stand the
vibration up to 50g’s with three redundant seals; slot seal, body seal
