Neles Series L12 Triple Eccentric Disc Valve
Brand: MetsoMetso's Neles Neldisc series L12 a wafer 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.
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 Differential pressure 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.
