TRICENTRIC Triple Offset Butterfly ValvesPERFORMANCEPressure/TemperatureTRICENTRIC metal seated valves perform favorably when compared toconventional, resilient seated and high performance butterfly valves overall service ranges. TRICENTRIC valves perform well especially at highpressure and temperature levels due to the following features: All alloy construction Flexible seal stack Non-rubbing metal seat Bubble tight shut-off Bi-directional, zero leakage Inherently fire safeTRICENTRIC valves have a long service history in nuclearpower dating back to the late 1970's.Single OffsetService RangesDouble OffsetTriple OffsetTRICENTRIC Triple Offset ValvesTRICENTRIC triple offset valves incorporate 3-way eccentricity. The metalseat is capable of very tight shut off at temperatures up to 1,500 F.compared to:HIGH PERFORMANCE (DOUBLE OFFSET)The eccentric shaft results in an uninterrupted seal which can be used athigher pressures and temperatures. However, the resilient seats wear andcan plug with solids.compared to:CONVENTIONAL (SINGLE OFFSET)Center shaft which penetrates a resilient seal.

TRICENTRIC Triple Offset Butterfly ValvesPRINCIPLE OF OPERATIONSEAT PLANESHAFTCENTER LINEOFFSET #2OFFSET #3DISC/SEALCENTER LINECONEAXISOFFSET #1The principle of operation incorporated in the TRICENTRIC triple offset valve is geometry in motion. Both the seat in the body and the seal onthe disc are surfaces of a cone which is sectioned at an angle. The valve shaft is located slightly to one side of the seat center and above theplane of the seat. Its center of rotation is also somewhat offset from the axis of the imaginary cone which extends from the surface of the seat.When the valve is closed, the surface of the seal and the seat are in full contact at all points. Any effort to try to further close the disc (rotatingit into the seat) increases the sealing force and tightens the valve. This allows the valve to achieve a bi-directional seal.Opening the valve, or rotating the disc away from its seat, results in the seal moving away from the seat at all points, eliminating rubbing orsliding of the seating surfaces, thus avoiding wear. TRICENTRIC valves feature true non-rubbing seating surfaces for long life and tight shutoff.TRIPLE OFFSET SEALING SYSTEMOffset #1The shaft is offset from the seat plane providing an uninterruptedseating surface.Offset #2Centerline of disc is offset from the centerline of the shaft allowingthe seal to freely lift off and away from the seat on opening.Offset #3The cone axis is offset from the centerline of the seal to provide aconical sealing surface that allows the seal to rotate in and out ofthe seat without interference, sliding or jamming.8Weir Power & Industrial First choice for power and industrial protection
TRICENTRIC Triple Offset Butterfly ValvesThe TRICENTRIC valve seal stack is designed to provide optimal sealing over thetotal product range. This is achieved by employing a laminated seal stack (stainlesssteel and graphite). The number of laminations depends on the size and pressureclass and is critical to performance. For special applications, a solid seal is available.Features and Benefits Triple offset metal seat design Long life seats Bearing protectors Bi-directional tight sealing Zero leakage Excellent throttling characteristics Frictionless seating eliminates galling and/or seat andseal wear Shaft does not penetrate through seat/seal lesssusceptible to seat leakage Shutoff is assisted by pressure seating improves aspressure increases Seal is not subject to ‘set’ like soft seated designs long term seating performance Torque seated, not position seated No need to“find sweet spot” for seal Self compensating seal will not stick due totemperature fluctuationsTRICENTRIC valve seal stack Larger shaft diameter with more bearing wearsurface longer life Robust shaft design to support full range ofactuator torquesDesign Standards / Criteria ASME B16.34 ASME Section III GL 89-10 (NRC Generic Letter) Actuator Sizing GL 96-05 Periodic Verification Testing ASME QME-1 Mechanical QualificationPressure ClassesASME CL. 150, 300 and 600FeaturesBenefitsMetal to Metal Seating SurfaceInherently Fire Safe–400 to 1,500 FSizesTorque SeatedZero Leakage3 – 96 in / 80 – 2,438 mmThird Offset and Conical SeatRepeatable Seat Tightness, Seal SelfCompensating during Thermal CyclingQuarter TurnQuick Opening & ClosingMaterials of Construction Carbon steels Alloy steels Stainless steels AL6XN Others available upon requestWeir Power & Industrial First choice for power and industrial protection9
