Neles Neldisc series L12 a wafe 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 Δp 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.

1. Applications

The Neldisc triple eccentric disc valves are widely used in applications such as:

• Liquids
• Gases
• Steam
• Pulpstocks both on control and shutoff services.

2. Special Features

• Third-generation, metal-to-metal seated Neldisc triple eccentric disc valve.
• Designed especially for paper and pulp applications.
• Light weight – easy to install.
• Compact overall design with minimal space demand.
• Can be mounted between all common pipe flanges.
• Two-shaft construction and seat located in the body groove give high flow capacity and minimum flow resistance.
• Excellent tightness by using the renowned Neldisc seating principle.
• Bidirectionally tight construction where seating is mechanically induced and does not rely on differential pressure.
