A nearly linear installed flow characteristic is available for many applications. Dynamic stability in both directions. Wide rangeability. Available with a variety of actuators, positioners and accessories for single source responsibility. Abrasion resistant Solid metal seat design (no fillers) offered in a variety of materials to suit your application. Fully metal-to-metal construction. No resilient parts exposed to the media. Wide pressure and temperature range Differential pressure/temperature ratings in accordance with ANSI B16.34. Appropriate constructions perform equally well from -196 C to +800 C / -320 F to +1500 F. Inherent fire-tite design Fire-tested per API 607 and BS 6755 part 2. Series L6 is a double flanged metal seated Neldisc butterfly valve for both demanding control and tight shut-off applications. It is particularly well suited for the refining, power, petrochemical and chemical industries. The L6 incorporates the Neldisc metal seated design, which provides extended life in high cycle, high temperature, abrasive applications, making it an ideal replacement for gate valves. It is available in sizes DN100-1500 / 4-60, fully rated to ANSI B16.34 for Class 150 and DN 100-1000 / 4-40 for Class 300. Flanges are designed per ANSI B16.5 for DN 100-600 / 4-24 valves and B16-47 for DN 700-1500 / 28 through 60 sizes. Rigid metal construction Rugged double flanged body. Suitable for use with API standard 601 spiral wound gaskets. Positive shaft retention. Single piece body eliminates potential leak paths associated with jointed bodies. High strength pins allow the valve to withstand high pressure drops in throttling positions. Low cost of ownership Extremely high cycle life minimizes need for maintenance. Change packing without removing actuator. Totally interchangeable seats can be replaced without disassembly of the disc and shaft. Offset shaft and eccentric disc No seat/disc contact in the open or intermediate position. Eliminates wear points at top and bottom of disc.

When the valve is closed, the elliptical disc at the major axis displaces the seat ring outward, causing the seat ring to contact the disc at the minor axis. When the valve is opened, the contact is released and the seat ring returns to its original circular shape. - 2 -
