15 APPLICABLE STANDARDS API 609 Butterfly Valves: Double Flanged, Lug- and Wafer- Type. The standard covers design, materials, faceto-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for gray iron, ductile iron, bronze, steel, nickel-base alloy, or special alloy butterfly valves that provide tight shutoff in the closed position and are suitable for flow regulation.

16 APPLICABLE STANDARDS API 598 Valve Inspection and Testing. The standard covers inspection, supplementary examination, and pressure test requirements for both resilient-seated and metal-to-metal to seated gate, globe, plug, ball, check, and butterfly valves. Pertains to inspection by the purchaser and to any supplementary examinations the purchaser may require at the valve manufacturer's plant.

17 APPLICABLE STANDARDS API6D Specification for Pipeline Valves. API 6D is an adoption of ISO 14313: 1999, Petroleum and Natural Gas Industries-Pipeline Transportation Systems- Pipeline Valves. This International Standard specifies requirements and gives recommendations for the design, manufacturing, testing and documentation of ball, check, gate and plug valves for application in pipeline systems.

18 APPLICABLE STANDARDS API 607 Fire Test for Soft-Seated Quarter Turn Valves. The standard covers the requirements for testing and evaluating the performance of straightway, softseated quarter-turn valves when the valves are exposed to certain fire conditions defined in this standard. The procedures described in this standard d apply to all classes and sizes of such valves that are made of materials listed in ASME B16.34.

19 APPLICABLE STANDARDS API 6FA Specification for Fire Test for Valves. The standard d covers the requirements for testing and evaluating the performance of API Spec 6A and Spec 6D valves when exposed to specifically defined fire conditions.

20 APPLICABLE STANDARDS ANSI B16.10, B , B16.47 Specification for pressure class and process connections that cover flanged and welded connection types and face to face dimensions.

21 Product Concept

22 Disc and Stem CN Double eccentric

23 Seat Style CN Typical Fire Safe Seat - POSITION SEATED - Rated according API 609

24 Seat Style CN Metal Seat - Rated according ANSI 150/300/600 - Tightness according ANSI Class IV

25 Series 30, Vanessa Revolution Triple offset ZERO Rubbing

26 GATE VALVES ARE TORQUE SEATED More Torque = More tightness

27 VANESSA TOV IS TORQUE SEATED More Torque = More tightness

28 VANESSA is a 1/4 Turn Gate valve

29 Series 30, Shutoff Capability All Vanessa valves are required to pass a Zero Leakage* test *Zero leakage is defined as the ability to pass a test per All International standards with ZERO bubbles of air and / or drops of water.

30 All Vanessa valves are tested to pass a ZERO LEAKAGE test ZERO leakage definition Zero leakage is defined as the ability to pass a test per ALL International standards with ZERO bubbles of air and/or drops of water

31 Series 30, Shutoff Capability Bubbletight is the most misused term! Bubbletight in accordance with ANSI/FCI 70-2 class VI or API 598 or MSS SP61 means Allowable Leakage. iin accordance with ANSI B cl.vi 8 valve = 45 bubbles per minute 24 valve = 400 bubbles per minute

32 Series 30, Zero Leakage valve API 598 API 598 ANSI/FCI 70-2 API 6D Diameter Metal Steated Soft Seated Class VI Rev.18 MM. INCH Liquid Air** Liquid Air Liquid/Air* 80 3" " " " " " " " " " " " " " ANSI/FCI 70-2 Class VI does not define leakage above 8 * Air test is optional ** Air test is required for butterfly and metal seated ball valves

33 Seat tightness Advantages of TOV over Gate valves Zero leakage compared to API 598 Better packing tightness Better Operability 48 closing in 0.15 seconds! Easily Repairable

34 Advantages of TOV over Gate valves No Jamming No Cavities Space & Weight savings Maintenance Control capability

35 Advantages of TOV over Ball valves Inherently Firesafe vs. Firetested Zero leakage metal seated Non Rubbing rotation o vs. 100% rubbing Less torque / Smaller actuators

36 Advantages of TOV over Ball valves Space & Weight savings Less maintenance Control capability

37 INHERENTLY FIRESAFE The valve is firesafe by design. The valve has no soft components that could be destroyed d by the fire. The valve does not change its performance before, during or after the fire.
