Butterfly valves

Neles Neldisc series LW and LG triple eccentric disc valves operate both in control and shut-off applications, with close to equal percentage characteristics and superior tightness.

Neles Neldisc series L1 and L2 triple eccentric disc valves operate both in control and shut-off applications, with close to equal percentage characteristics and superior tightness.

Neles Neldisc series L6 triple eccentric disc valve operate both in control and shut-off applications, with close to equal percentage characteristics and superior tightness.

Neles Neldisc series L12 triple eccentric disc valve operate both in control and shut-off applications, with close to equal percentage characteristics and superior tightness.

Neles BN series is a cost-effective full bore butterfly valve with a one piece body and an eccentric soft seat. It is specially designed for industrial gas applications featuring long-lasting tight shut-off capability, excellent flow characteristics and long service life. BN series butterfly valve is also used in control applications.

Intelligent, reliable on-off Neles valve solutions for general and high-cycle applications will help to reduce the life-cycle costs. Our valve solutions provide long lasting tight shut-off with fast and safe operation together with reduced fugitive emissions. Neles shut-off valves combined with intelligent valve controllers provide diagnostic capabilities and increase plant safety.

Neles lever valves are designed to air separation unit air inlet shut-off valve. They feature self-locking safety design for a specified differential pressure. The lever arrangement provides valve operation with low friction. The sealing sections are not subjected to abrasion wear, resulting in extremely low torque level.

Neles BO series butterfly valve is designed for Vacuum Pressure Swing Adsorption plants (VPSA). It is a wafer type, soft seated, high performance, single eccentric disc valve. The valve provides maximal endurance in fast cycling. Additionally, it provides long lasting tight shut off with excellent flow characteristics and high capacity while maintaining the internal tightness even up to 2 million cycles.

Reliable intelligent emergency shutdown (ESD) valves and actuators with Neles™ ValvGuard™ intelligent valve controllers improve your plant safety cost efficiently. In Neles we have combined our know-how of valves, actuators, safety standards (IEC61508/61511), applications, system operability and partial stroke test devices with intelligent prediction tools. Diagnostic information is presented understandably to enable planned maintenance of potentially failing valve assemblies before they have a chance to impact the process or safety.
