8 PRINCIPLE OF OPERATION The Velan Triple-Offset Butterfly Valve provides a bidirectional 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 with sufficient wedging to ensure a uniform seal contact. THE TRIPLE-OFFSET GEOMETRY OFFSET 1: The shaft is offset behind the seat axis to allow complete sealing contact around the entire seat. OFFSET 2: The shaft centerline is offset from the pipe and valve which provides interference free opening and closing of the valve. OFFSET 3: The seat cone axis is offset from the shaft centerline to eliminate friction during closing and opening and to achieve uniform compressive sealing around the entire seat. FRICTION FREE SEALING FOR LONG CYCLE LIFE THE LAMINATED DISC SEAL Retainer ring Laminated disc seal Disc Gasket (2) Hardfaced seat (1) Torque seating during closing of the valve provides uniform forces around the entire circumference of the valve seat. The resilient seal flexes and energizes, assuming the shape of the seat. The compression forces equally distributed around the perimeter provide a tight bi-directional shut off. The resiliency of 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. Body Radial Loading Velan provides an extra rigid retaining ring with bolting, designed in response to ASME stress calculations. (1) Seat is hardfaced with Stellite as standard. (2) The gasket is spiral wound SS/Graphite for zero leakage. 6
9 VALVE DESIGN FEATURES The Torqseal s advanced design features three-way eccentricity and unique elliptical seat geometry ensuring compressive sealing around the entire seat and a tight, bubble free valve. STELLITE HARDFACED SEAT Detail A HP Raised, conical seat prevents solids build-up from interfering with the seal. Seat is hardfaced with Stellite to meet severe service (in lieu of soft 316SS hardfacing). STANDARD LAMINATED RESILIENT DISC SEAL TO 800 F (427 C) One to four graphite layers are carefully assembled between stainless steel rings and graphite using phenolic resin bond. Solid seal rings are available for abrasive services as well as high temperature applications up to 1112ºF (600ºC). Detail A LOAD NOTE: The valve is marked HP for the preferred pressure side when installing the valve (shaft side is the high pressure side for flow assisted sealing). Valve is bi-directional. TRIPLE SHAFT BLOWOUT PROTECTION CONFORMS TO API 609 Internal Internal External HP "ZERO LEAKAGE" - SEAT TIGHTNESS (API 598 RESILIENT SEAT STANDARD) The disc seal, evenly compressed around its circumference, produces a wedging effect which flexes the seal ring and reacts like a spring. The resilient seal assures "zero leakage" of liquids or gases to API resilient seat standard. Resiliency in the seal allows disc movement during thermal cycles while retaining tight shutoff as shown. NO CAVITY There is no cavity to allow build-up of solids. ONE-PIECE SHAFT Large diameter shaft for safety is connected to the disc close to the bearings to absorb loads with taper pin and key to allow for differential expansion due to temperature. SHAFT BEARINGS The shaft is centered on two long bearings, chromed, nitrided, or as stellite (option) protected against the entrance of solids by bearing seals which are standard on Torqseal valves. LOW EMISSION SHAFT SEALS ppm Shaft is burnished to 8 RMS, ID of packing chamber finish 32 RMS. Live-loading available for long maintenance-free service. Easy access for packing adjustment. (See page 8 9 for details and alternative stem seals.) CERTIFIED TO API 591, PED & ASME N (UPON REQUEST) 7
10 NEW STEM SEAL TECHNOLOGY PIONEERED BY VELAN As a result of extensive tests conducted by Velan between 1966 and 1972, a new technology emerged at the time for high performance, leakproof, long life, and low maintenance stem seals for nuclear power, now available for all industries and applications. 1. STANDARD LOW EMISSION STEM SEAL WITH PPM Velan is continuing its efforts in updating the low emission technology which, in the case of butterfly valves, concerns the stem seal alone (no body-bonnet joint) to newly emerging standards. OPTIONAL LIVE-LOADING provides predictable and constant packing compression for more than 5000 cycles before adjustment or re-packing. 1) Short and narrow packing chamber Maximum 5 rings, 1 /4" wide. 2) Large compression load required Graphite rings precompressed to 4000 psi for effectiveness of all rings. Gland torque must be maintained after installation and in service to levels shown in manuals. 3) Superior finish (32 RMS) of packing chamber and stem (8 RMS) to assure long cycle life. Stem bearing 4) Stem bearing to assure concentric stem rotation, allowing stem packing to provide maximum sealing effectiveness. 5) Two-piece gland with spherical mating surfaces to assure an even packing load over STEM SEAL WITH 0 HELIUM BUBBLES Graphite high density Graphite low density Braided Graphite FEP TYP. Special High Performance Packing is installed and then compressed using gland bolting to approximately 80% of its "free length". The inherent sealing ability due to its cup and cone technology and excellent quality of materials has been proven in standard and very difficult valve applications, all backed up by an intensive research program. 8
11 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 a maximum leakage of less than 1 ppm ( ppm) for critical valves. Certification issued after extensive pressure and cycling tests with H.P. helium, witnessed by TA-LUFT inspectors, assures the design and performance of a given stem seal to be equivalent to a bellows seal design. Velan has qualified two different stem seal designs to the TA-LUFT regulations. 3. THE TA-LUFT* SEAL WITH LESS THAN 1 PPM ( PPM) EMISSIONS * Technical instructions to maintain cleanliness of air. 1) Fully-guided stem Stem bearings in body and gland follower prevent wobbling and packing leakage due to side thrust on stem. 2) Precompressed packing rings to 4000 psi. 3) Two O-Rings in gland follower provide additional stem seal protection to assure emissions of less than 1 ppm. 4) Live-loading Provides constant packing compression and is essential for this packing arrangement. 5) Two-piece flanged gland. 6) Superior finish of packing chamber (32 RMS) and stem (8 RMS) to assure long life. 4. LANTERN RING OPTION DOUBLE PACKED WITH LEAK-OFF MONITORING PURGE PORT OPTIONAL LIVE-LOADING provides predictable and constant packing compression for more than 5000 cycles before adjustment or re-packing. Double packing with leak-off monitoring purge port. Two sets of packing rings, precompressed to 4000 psi (graphite). A lantern ring and leak-off connection allows removal of leakage, if any, from bottom packing set. 9

18 RELIABILITY THROUGH FUNCTIONAL QUALIFICATION Reliability of valve operation affects service life and maintenance. To predict reliability, a sound valve design, backed up by a stress analysis must be subjected to functional cycle testing under critical operating conditions. To develop the Velan Torqseal Triple-Offset Metal-Seated Butterfly valves, it required an unusual effort and extended period of time as many competitive valves in the same category, tested in our R&D, showed repeated leaks of seats and laminated disc gaskets. Some highlights of the tests performed in our R&D laboratory are shown here. Detailed reports are available on request. HYDROSTATIC TESTS Valve passed testing with zero leakage. COLD CYCLING TEST (1000 CYCLES) 820 psi water to test preferred seat side. 490 psi water to test non-preferred seat side. Cold temperature testing to -314ºF. R&D testing of the Cryogenic Torqseal valve in our Lyon, France facility. ACCEPTABLE RESULTS API 598 resilient seat standard for laminated seal. API 598 metal seat standard for solid seal. HOT CYCLING TESTS Requirement: 1000 Cycles psi superheated steam at F. The valve under flow of steam at psi superheated to F passed 7250 cycles without seizing or jamming. Seat bubble test performed on 8 ISO Class Lug style Torqseal valve. (0 bubbles accepted). AMBIENT CYCLING TESTS Valve passed: 5000 Cycles with preferred flow direction, 3000 Cycles with nonpreferred flow direction and zero leakage at seats and gasket. Also tested 8 Class 300 to 30,000 cycles with no jamming. 8 Class 300 valve during hot cycling test (see above). 8 Class 150 valve - ambient cycling. Steam test on 14 Class 150 valve. 16
19 TESTS INCLUDING FIRE TESTING TO API 607, REV.4 API 607, REV. 4 FIRE TEST 8 Class 150 valve before the fire test. 3. Rapid water quenching lowers the valve temperature to below 212 F (100 C). This is performed twice, once in each direction. TEST REPORTS 1. The valve was tested first to API 598 with zero seat leakage in preferred and non-preferred direction and zero external leakage. 2. Valve during burn period is exposed to F ( C) flames for the duration of 30 minutes. Then the test is repeated in the non-preferred direction. Valve after two fire tests, maintains zero seat and stem seal leakage.

20 AIR AND ELECTRIC ACTUATORS Velan supplies high quality actuators for pneumatically, electrically and hydraulically operated butterfly valves. All actuators are totally enclosed. All moving parts are permanently lubricated. Actuators can be installed in the field although it is preferable that they be installed and tested in the factory. ACTUATION GUIDELINES The Torqseal Triple-Offset design concept of the Torqseal Butterfly Valve differs from that of a standard quarter-turn valve in terms of seating characteristic. A typical valve (i.e. ball or high performance butterfly) is position seated and has a set rotation of 0 to 90º. In order to prevent over-traveling when automating this type of valve, travel stops are used on air operators and limit switches on motor operators. The Torqseal Triple-Offset Butterfly Valve, on the other hand, is torque seated and requires a set torque from the operator to fully close the valve. Because of this characteristic, there is no defined seating position, and in general the valve requires 5-10º of over-travel for a tight seal. Therefore, the travel stop or limit switch should not be used on the closed position. The actuator s closing torque, properly sized for the application and valve size, should be used instead. In order to protect the valve stem, this torque should always be limited by either: a) The torque switch in a motor operator. b) The spring torque in a fail-closed air operator. c) A regulator for a double-acting or fail-open air operator. OPTIONS STEM EXTENSIONS Torqseal valves are available with stem extension for buried service applications among others. Chain wheel operators are also available. STEAM JACKETS Steam jackets are also available for Torqseal valves in both the bolt-on and weld on design. Torqseal valves with steam jackets are an ideal choice for applications where the media tends to crystallize when cooled down, such as sulphur and other applications. SPECIAL CLEANING Special cleaning (oxygen, chlorine etc.) available on all Torqseal valves. Please consult the factory for further information.
