VELAN MEMORY SEAL BALL VALVE TECHNOLOGY

SEALING MEMORYThe Velan sealing memory is induced into the seatsduring the assembly process. When the ball isinserted into the valve body during assembly, itpartially flattens the seat, creating a tensile stress inthe center of the seat.

As a result, the seat core increases in diameterfrom D1 to D2 and like a stretched elastic bandpushes against the ball. This ensures reliablesealing even at vacuum or low pressures.

SEAT STRENGTHA seat in tension is stronger than a seat incompression because the tensile strength of PTFEin tension is 3600 psi versus only 1800 psi for PTFE in compression. Greater strength means less fatigue,superior sealing ability and longer cycle life.

CAVITY PRESSURE RELIEFMemory seal seats are designed to relieveoverpressure in the ball/body cavity. This capabilityis influenced by many variables including: fluidcharacteristics, variations in pressure, seatmaterials, seat compression, temperature andthermal cycles.

Positive release of cavity overpressure to theupstream side is assured in bypassing the upstreamseat through a drilled hole in the ball. This option ispreferred in certain services such as liquid chlorine.

SUMMARY OF MEMORYSEAL BENEFITS

� SEATS ”IN-TENSION“

- Greater strength

- Less fatigue

- Positive bi-directional shutoff

- Compensate for temperature fluctuations

- Uniform torque

- High cycle life

- Eliminate cold flow effects

� LARGER SEATING AREA

- Superior sealing

AREA IN COMPRESSION

AREA IN-TENSION

D1 D2

LOWER TORQUESVelan “in-tension” seats produce more uniformtorque because the seat deflects into the cavitybehind it to accommodate slight differences inmachining tolerances or the normal expansion ofPTFE as temperature increases. PTFE expandsapproximately seven times as much as metal.

1 Two-leakage paths (gasket and packing).

2 Fully guided stem.

3 In lab tests 0 ppm emissions to 100,000 cycles, 500,000 with live-loading.

4 Easy to weld the one-piece body into the line without disassembly. The integrity of the valve isnot affected.

5 All parts can be easily serviced or replaced in-line.

1 Three-leakage paths (2 gaskets and packing).

2 Stem can wobble, cause leakage.

3 Larger emissions, lower cycle life.

4 Welding can affect the integrity of the valve due to tendency to separate the three-boltedbody parts during the welding.

5 Valve can not be serviced in-line, because of thefire safe design with spiral wound gaskets whichrequires internal guiding of the two end pieces.The guiding prevents the centerpiece to swing out.

1. Fully-guided stem.Stem bearings in cover and in the gland follower preventwobbling and packing leakagedue to side thrust on stem.

2. Two piece flanged gland design for low fugitive emissions andsevere 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 operating torque and providesa secondary stem seal.

5. Blowout-proof. The internally-backseated stemprovides blowout-proof safety.

6. Antistatic devices. The stem is grounded againstbody by contact with Bellevillewashers or coil springs.

7. Optional Live-loading. For temperature cyclingapplications and/or forconformance to TA-Luft,additional steady compressionload can be provided byinstalling sets of Bellevillewashers.

MATERIALS

CHLORINE SERVICEChlorine is extremely corrosive and toxic. Corrosion increases with the percentage of water moisture. Up to50 parts per million or 0.005% water, chlorine is considered dry. Above this level, it is wet. The liquid gascurve of chlorine is shown in the diagram below. There is also danger due to a high coefficient of thermalexpansion. When cold liquid chlorine is trapped in the non-expanding space of the ball valve cavity, high destructive pressures can develop.

(1) Saturated steam, on/off operation.

(2) Consult ASME B 16.34 for body pressure-temperature rating.

CRYOGENIC SERVICEValves to be used in cryogenic service have extended stems located in asufficiently long tube to provide an insulating gas column above the cold fluid to prevent shrinkage of the stem packing and to prevent the formationof an ice ball around the gland and packing.

A 1⁄8" vent hole is provided in balls for cryogenic ball valves. Standardmaterial for cryogenic service is austenitic stainless steel for all parts andbolting, offering excellent impact strength, minimizing heat loss andprotecting against corrosion. When welded, Inconel electrodes are used forall austenitic stainless steel valves.

TESTINGValves can be qualificationtested at cryogenic temperatureswith nitrogen gas.

SPECIAL CLEANINGAll cryogenic valves arethoroughly degreased, cleaned, and pipe ends sealed to prevent contamination.

LIVE-LOADED BODYBOLTING (OPTIONAL)For applications whererapid temperaturefluctuations (example:LNG loading platform)can cause joint leakage, body-bonnet boltingis live-loaded withBelleville spring washers.

CALCULATION OF THE ACTUATOR TORQUE REQUIREMENT

When determining the required actuator torque, seat material, fluid and frequency ofoperation should be considered according to experience and judgement. For actualrequired torques, for your application or valve automation, contact Velan or theauthorized Velan automation center of your choice.

Velan is not responsible directly nor indirectly for actuator selection by third parties.

STEM PACKING DESIGN FOR AUTOMATION AND CONTROL

TA-LUFT qualification test on a top-entry ball valve.

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 quali-

fication tests by inspection agencies.

This assures trouble free service in

automated and throttling control and

the best in stem packing integrity.
