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


  • 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
  • Wide material selection available for different applications
  • Flanged and welding-end body options
  • Low emissions according to ISO 15848, bellows packing available
  • NACE material options
  • SIL 3 certified
  • Special cleaning optional for oxygen, cryogenic etc. service
