Neles™ cage-guided angle valve, series AB

The Neles AB series of globe valves offer exceptional control performance and reliability for situations where there are high pressure drops and velocities. These angle valves are often utilized in scenarios where there is flashing or in piping systems with restricted space.


  • Maintenance is simple as the valve can be replaced without removal from the pipeline
  • Ownership cost is low and maintenance needs are minimized
  • Process stability and noise are effectively controlled
  • ISO 15848 compliance ensures low emission


  • A single-piece body design reduces potential leakage points.
  • The angled body pattern is ideal for installations involving angled pipelines.
  • Particularly well-suited for flashing applications, the high-velocity flow can be directed through the valve with minimal contact to body and internal components, thus increasing the valve’s lifespan.
  • The valve features a top-entry design and quick-change trim for hassle-free maintenance.
  • As a standard feature, the valve boasts heavy-duty cage-guided trim construction and hardened trim surfaces, which result in extended service life.
  • The valve offers a wide range of trim capacities and characteristics to optimize performance.
    Multi-hole Tendril™ trim reduces noise and eliminates cavitation.
  • A broad selection of materials is available to suit various applications.
  • The valve is available in both flanged and welding-end body options.
  • The valve is designed for low emissions and is ISO 15848 compliant, with bellows packing available.
  • NACE material options are available.
    The valve is SIL 3 certified.
  • Special cleaning options are available for oxygen, cryogenic, and other services.
