Oil, gas, petrochemical, chemical, power, nuclear, and marine-applicable TVT triple off-set butterfly valves are described, illustrated, diagrammed, and specified in this free brochure.
Its 28 pages highlight patented TVT metal-seated designs emphasized to have successfully passed fire-type testing requirements: BS EN ISO 10497:2004 and API Std 607:2005, 5th edition.
Butterfly valve design features are cited to include triple offset circular conical sealing geometry, genuinely bi-directional, zero leakage, and zero sealing friction. Cutaway illustrations and graphics depict valve ‘cam action’ and ‘right angled conical sealing’ design. These ensure metal sealing components are never in contact until its final degree of closing — for repeatable sealing and extended valve life. Among numerous TVT applications are isolation of reservoirs and storage, LPG or LNG lines, desalinization, hydrocarbons transport, desulfurization systems, ethylene or propylene plants, tail gas and services with hydrocarbons.
