Raised, conical seat prevents solids build-upfrom interfering with seal. Seat is hardfacedwith Stellite to meet severe service. Alternative space age alloys are also used.
�LAMINATED
RESILIENT DISC SEAL
to 1000°F (538°C)
One to four graphitelayers are carefullyassembled betweenstainless steel ringsusing Phenolic Resin.Flexible seal ringswithout glue areavailable for highertemperatures.
�"ZERO LEAKAGE" - SEAT TIGHTNESS
The disc seal, evenly compressed around itscircumference, produces a wedging effectwhich flexes the seal ring and reacts like aspring. The resilient seal assures "zero leakage"of liquids or gases to API 598 - resilient seatstandard. Resiliency in the seal allows discmovement during thermal cycles whileretaining tight shutoff as shown.
�NO CAVITY There is no cavity (contrary to Gate Valves) to allow build-up of solids.
�ONE-PIECE SHAFT Large diameter shaft forsafety is connected to the disc close to thebearings to absorb loads with taper pin and key to allow for differential expansion due totemperature.
�SHAFT BEARINGS The shaft is centered on two long bearings, chromed, nitrided, or asstellite (option) protected against the entranceof solids by O-rings (Bearing flush tapsavailable as an option).
�LOW EMISSION SHAFT SEALS 0–20 ppm
Shaft is burnished to 8 RMS, ID of packingchamber finish 32 RMS. Live-loading availablefor long maintenance free service. Easy accessfor packing adjustment. (See page 8 for detailsand alternative stem seals.)
This advanced design features three-way eccentricity and unique elliptical seat geometryensuring compressive sealing around entire seat and a “tight” bubble free valve.

THE TRIPLE OFFSET GEOMETRYOFFSET 1 The shaft is offset behind the seat axis to allow
complete sealing contact around the entire seatOFFSET 2 The shaft centerline is offset from the pipe and valve
which provides interference free opening and closingof the valve
OFFSET 3 The seat cone axis is offset from the shaft centerlineto eliminate friction during closing and opening andto achieve uniform compressive sealing aroundthe entire seat.
THE LAMINATED DISC SEALSeating forces are generated by the torque during closinguniformly around the entire circumference. The resilient sealflexes and energizes, assuming the shape of the seat. The compression forces equally distributed around theperimeter provide a tight bi-directional shut off. The resiliencyof the seal allows the valve body and disc to contract or expand, without the risk of jamming due to temperature fluctuations. It is self-adjusting.
The Velan Triple Offset Butterfly Valve provides a bi-directional bubble tight shut-off. This geometry ensures that the disc seal contacts the body seat only at the final shut-off position without rubbing or galling, providing a torque generated resilient seal withsufficient “wedging” to ensure a uniform seal contact.

Double packing with leak-off monitoring purge port.Two sets of packing rings, precompressed to 4000psi (graphite). A lantern ring and leak-off connectionallows removal of leakage, if any, from bottompacking set.
ASSURES LOWEST POSSIBLE ENVIRONMENTAL EMISSIONS
The new European specification, called TA-LUFT which is controlled by a section of the German TUV agency(Technischer Überwachungs-Verein), demands for critical valves a maximum leakage of less than 1 ppm(0.0014 ppm). Certification issued after extensive pressure and cycling tests with H.P. helium, witnessed byTA-Luft inspectors, assures the design and performance of a given stem seal to be equivalent to a bellowsseal design. Velan has qualified two different stem seal designs to the TA-LUFT regulations.

1) Short and narrow packing chamber Maximum 5 rings, 1/4" wide.
2) Large compression load requiredGraphite rings precompressed to 4000 psi for effectiveness of all rings. Gland torque mustbe maintained after installation and in service tolevels shown in manuals.
3) Superior finish (32 RMS) of packing chamber andstem (8 RMS) to assure long cycle life.
4) Stem bearing to assure concentric stem rotation,allowing stem packing to provide maximumsealing effectiveness.
5) Two-piece gland with spherical mating surfacesto assure an even packing load over 360%.
1. STANDARD LOW EMISSION STEM SEALWITH 0-20 PPM
1) The Garlock EVSP 9000 High PerformancePacking is installed and then compressed usinggland bolting to approximately 80% of its "freelength". The inherent sealing ability due to itscup and cone technology and excellent quality of materials has been proven in standard andvery difficult valve applications, all backed up by an intensive research program carried out by BP-Amoco, calling it the EnvironmentallyFriendly Valve Technology.
2) 10% of valves are tested for compliance or zerohelium bubbles with helium leak detectors, at the highest, cold operating pressure for agiven pressure class (150 & 300).
2. EFV* STEM SEAL WITH “0” HELIUM BUBBLES
* Environmentally Friendly Valve
As a result of extensive tests conducted by Velan between 1966 and 1972, a new technology emerged at thetime for high performance, leakproof, long life, and low maintenance stem seals for nuclear power, nowavailable for all industries and applications. Velan is continuing its efforts in updating the low emissiontechnology which, in the case of butterfly valves, concerns the stem seal alone (no body-bonnet joint) tonewly emerging standards.

RELIABILITY THROUGH FUNCTIONAL QUALIFICATION TESTS
Reliability of valve operation affects service life andmaintenance. To predict reliability, a sound valvedesign, backed up by a stress analysis must besubjected to functional cycle testing under criticaloperating conditions.
To develop the Velan Torqseal Triple Offset Metal-seated Butterfly valves, it required an unusual effort
and extended period of time as many competitivevalves in the same category, tested in our R&D,showed repeated leaks of seats and laminated discgaskets. Some highlights of the tests performed in ourR&D laboratory are shown here. Detailed reports areavailable on request.
