METAL SEATED NELES ZEROLEAK NELDISC BUTTERFLY VALVES, SERIES L1 & L2

Transcription

1 METAL SEATED NELES ZEROLEAK NELDISC BUTTERFLY ALES, SERIES L & L Neldisc series L is a wafer type and series L a lug type metal seated high performance butterfly valve. With close to equal percentage characteristics and superior tightness Neldisc butterfly valves operate both in control and shut-off applications. As a result of the unique geometry of Neldisc, the contact between disc and seat is mechanically induced and does not rely on assistance from differential pressure. The valve is very tight even in low p applications. Due to a number of special constructions developed from the versatile Neldisc design, these valves offer a powerful tool for standardization and are true high performance valves. ZeroLeak features Metal to metal Bidirectional long term tightness Low friction Excellent wear resistance Extended life cycle Lower operational torque Applications The Neldisc butterfly valves are widely used in applications such as: Liquids Gases Steam Pulpstocks both on control and shutoff services. FEATURES Bidirectional tight seat Unique all-meatal seat design assures superior tightness in difficult applications over long time periods. Contact between disc and seat is mechanically induced and does not rely on assistance from differential pressure. Abrasion resistent Solid metal seat design offered in a variety of materials to suit your application. Fully metal seated construction with no resilient parts exposed to the medium. Wide pressure and temperature range Differential pressure/temperature ratings in accordance with ASME B6.. Appropriate constructions perform equally well from -00 C to +800 C / -0 F to +80 F. 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. Anti-blow out shaft Anti-blow out shaft construction standard in all valves, see page exploded view. L EN Issue 9/00

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. Stainless steel ASTM A 5 gr. CF8M Stainless steel ISO 506 A
