Neles™ top-guided angle valves, series AU

Superior control performance and high reliability for applications with high pressure drop and high velocities.

Neles series AU globe valves provide superior control performance and high reliability in applications where pressure drop and velocities are high. Angle valves are commonly used in flashing applications or in piping layouts with limited amount of space. Standard units are equipped with Neles diaphragm actuators and Neles valve controllers for precise flow control, extended operation life and performance monitoring online.

Easy maintenance - valve can stay in the pipeline while replacing parts

Low cost of ownership and minimized maintenance need

Stable process and noise control

Low emissions according to ISO 15848

Features

One piece body to minimize the leak paths
Angle body pattern for angle pipeline installations
Especially suitable for flashing applications because high velocity flow can be guided through the valve with minimal contact to body and internals which increases valve lifetime
Top-entry construction and quick-change trim for easy maintenance
Rugged top-guided trim construction and hardened trim surfaces for extended lifetime as default
Wide variety of trim capacities and characteristics to optimize valve performance
Multi-hole Tendril™ trim to reduce noise or to eliminate cavitation
