Series 30,000 Rotary Process - valve sales and valve ...

1 Flow ControlSeries 30,000 Rotary ProcessValve1 Vanessa has been successfully producing andmarketing valves worldwide for almost four having been a subsidiary of Keystone, the companyjoined Tyco International Ltd. in 1997 to operate withinone of its core business segments, Tyco Flow Control. In2000, Vanessa became part of Tyco valves & ControlsItalia , a leading European valve manufacturing group,which includes the Raimondi and Fasani brand 1975 Vanessa was the first company to introducethe revolutionary metal-to-metal seating technology intothe market by offering the Series 30,000 Rotary ProcessValve, a unique quarter turn, triple offset, zero leakagevalve. This has enabled end users to cover a huge varietyof applications in many different industries and has givenVanessa an enviable reputation world-wide. Today, as from its inception, Vanessa is theinternational leader in the manufacture of high technologyrotary Process achievements of the Vanessa valve in theinternational market have allowed a constant growth ofthe company.

2 The reasons for its success can beattributed to the use of advanced technology,sophisticated quality control systems and above all theexclusive design of the Series 30,000 . Vanessa is committed to a constant improvement ofits technology and equipment, an attitude which hascontributed to the highest levels of performance of itsproducts and the satisfaction of its thrust bearing The high-cycle thrust bearing assemblyrigidly fixes a super hardened thrustwasher to the shaft while maintaining anintermediate sliding thrust washer, toextend an already long cycle life. Stellite hard-face seatHardfacing ensures durability in thebroadest range of applications, includinghigher temperatures and dirtier seat is standard on the completerange of 30,000 metal seated, Company ProfileResilient metal sealThe flexible, resilient metal seal is locatedon the disc and is secured but not lockedin position, so that the metal seal has thefreedom to flex. The seal ring is locatedwith a reference pin.

Additionally,Vanessa packing may be flexiblyarranged into numerous configurations,including packing and bearing flush orpacking monitoring. Fugitive emissionsare in accordance with the most stringentEPA and TA Luft requirements. zero leakage Rotary Process Valves3 Resilient Metal Seal RingDesign FeaturesOffset 3 Achieved by inclining the seat and seal cone centerline inrespect of the pipe and valve centerline. This third offsetcompletely eliminates rubbing. Any chances of associatedwear and leakage between the seat and disc-mounted sealring during travel are optimizes the contact angle between the seat andseal for enhanced performance.

4 Most gate valves provide acontact angle of between 3 and 6 degrees. Such designscreate a locking taper that can cause dangerously high seat-ing or unseating s contact angle is above the locking taper range andits geometry eliminates the possibility of jamming, ensuringthe forces necessary to seat or unseat the valve do not sub-stantially vary over the service life of the seat contact* Zero Leakage means no visible leakage during test durationas per API 598 and/or API 6D.

5 These shaft offsets are created by designing thevalve with the shaft located behind the centerline of thesealing surface and slightly to one side of the pipecenterline. The purpose of these offsets is to reduce therubbing and thus the wear between the seat and seal toapproximately 20 degrees of adds a unique third (inclined cone offset 3) to allow not only camming, but also tocompletely eliminate all seat-to-seal rubbing throughout thevalve s entire 90 degrees of Metal SealThe Vanessa Series 30,000 utilizes a resilient, duplexstainless steel seal ring installed in the disc assembly toprovide true zero leakage*.The resilience of the seal ring isachieved through the radial compression of the seal ringas torque is applied to the valve shaft. The seal and seatcontact surface is cone-in-cone, where both cones areinclined. The angle of contact between the seal and theseat allows the torque applied to the shaft to radiallycompress the disc seal ring. By maintaining uniformity ofcontact angles and elasticity in the seal ring, the entirecircumference of the seat is evenly loaded to achieve thetightest shutoff with the least amount of torque.

7 Stellite hardfaced standard integral seatresults in broader applications, longer valvelife and less maintenance. Single-piece cast body, with face-to-facedimensions in accordance to ISO 5752, API609 and ASME provides interchange-ability with gate, ball and plug valves . Integral position indicators on the stem andon the top mounting flange ensure positivedisc position indication, in accordance withAPI 609. All metal construction and sealing and zeroleakage performance translate into an inher-ently firesafe valve . Long-length hardened bearings, incorporat-ing a standard reinforced,die-formed, flexible and replaceable graphitebearing protector ensure additional reliability.

The extended bonnet helps maintain the packing operating temperature at normal levels, and this greatlyreduces any risk of fugitive emissions. The actuator remains protected from extremely high line temperature. The reliability of the valve performance is guaranteed by the appropriate high temperature materials selec-tion. The high temperature configuration is widely used in oil and gas processing, power and chemical fields,usually for services involving hot gases and steam.

Other materials available on An excellent configuration to prevent any fluid crystallization in presence ofparticular media. The heat diffused by valve body jacket reaches all the critical areas, in particular the valve seat and thebearings area. The jacketed valve is manufactured using the double flanged body style. Vanessa recommends the useof a long face-to face pattern which increases the heating action.

10 The jacket is dimensioned according to ASME Boiler and Pressure Vessel Code. For particularly harsh applications, Vanessa advises to use its Steam Jacketed and Traced Trim configu-ration. The addition of the traced trim provides an internal heating system obtained by drilling the shaftfrom top to bottom, to maximize the heat transfer to shaft and bearings.
