Neles™ Neldisc™ wafer type L6 series metal seated, triple eccentric disc valves are specially designed to fulfill the requirements of chemical, petrochemical, and refining industries.
Neles™ Neldisc™ wafer type L6 series metal seated, triple eccentric disc valves are specially designed to fulfill the requirements of chemical, petrochemical, and refining industries. With nearly equal percentage characteristics and superior tightness, Neldisc™ valves operate both in control and shut-off applications.
The Neldisc™ triple eccentric metal seated design, provides extended operational life in tight shut-off, high cycle, high temperature, and abrasive applications. Also, the contact between the disc and seat is mechanically induced and does not rely on assistance from differential pressure.
The unique S-disc flow treatment option expands application possibilities beyond those of typical butterfly valves.
