BONETTI TRUNNION MOUNTED FULLY WELDED BALL VALVES API 6D-0404
BONETTI Fully Welded trunnion ball valves The best solution to avoid fugitive emissions in gas or underground applications The BONETTI s fully welded, trunnion mounted ball valves are the most reliable solution to minimize the risk of leakage or fugitive emissions from valve body and stem seal. They are recommended for oil and gas applications, specially for gas transmission and storage. To comply with the specific requirements of such application, all valves are bidirectional and include the double block and bleed feature. Therefore, venting and draining of the body cavity is possible in both open and close positions. All valves are manufactured using forged steel. Seat inserts can be thermoplastic polymers or metallic, as standard. On request, the new exclusive BONETTI patented HTL seating is available (refer to page 4). Design, manufacture and materials comply with all recognised and accepted international standards. 2 BONETTI

Other options and notes - Seat area with hard face weld overlays or special coatings available - Operator protection in case of upper stem seal disassembly. All disassembly functions can be carried out under safe conditions : 1 Double Block and Bleed design. The body cavity is isolated from the line pressure (closed/open position). 2 Lip seal provided for each size and rating. 3 Vent valve provided for each valve size/rating. It must always be in place during seal replacement as indicated in the Operation and Maintenance Manual. The new BONETTI HTL seating This revolutionary design, using alternating layers of pure graphite and stainless steel (or other alloys on request), assure bubble tight seat shut-off with a very low operating torque while rated for high pressure and temperature (up to 550 C 1020 F in presence of Oxygen (or higher in absence of it). Seat features: Multilayer metal/graphite seating system: each single layer guarantees an independent sealing. Damages to some layer do not affect the sealing capacity of the others. Zero leakage bubble tight shut-off due to machining accuracy, low tolerances, multiple lamination and the resilient metal/graphite to metal sealing that allows severe differential expansions and self compensation for high differential temperatures between ball and seat without affecting the perfect tightness of the valve. Low torque operation is guaranteed both by the resilience of the multilayer seat ring as well as by the self lubrication of graphite. A smaller actuator size and lower torque is needed to operate the valve. Intrinsically fire-safe design thanks to seat components that are noncombustable, making the HTL equipped valves fire-safe. The valve performance will not change in case fire should occur outside or inside the valve. The high resistance to erosive media containing abrasive particles, yelds perfect sealing with practically endless valve life, even after hundreds of thousands of operating cycles.
