Metso's Neles Neldisc series L1 is a wafer type and series L2 a lug type metal seated high performance triple eccentric disc valve. With close to equal percentage characteristics and superior tightness Neldisc triple eccentric disc valves operate both in control and shut-off applications. Light valve construction paired with Neles B-series actuatorprovides cost-competitive solution for control and on-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 saving investments cost. The valve is very tight even in low dp applications.
