Linear Cage Control Valve Type LTG3

Globe straight-way LTG3 series is a very versatile control valve for the main applications. Its high performance derives by using a balanced and cage-guided plug. LTG3 is particularly suitable for heavy duties and for any other application under most demanding service conditions. Due to their simple construction, to the large range of trim types and available materials, these valves are suitable for a wide range of applications, including also high temperature and corrosive fluids, severe low-noise requirements and sour service in accordance with NACE standard.
Main advantages:

  • High pressure drop capability with no practical limitations
  • Improved plug stability due to large guiding areas
  • Wide-range capability is allowed by a great number of reduced capacity trims
  • Excellent noise attenuation with low-noise single-stage trim for gas and steam service
  • Improved cavitation protection on liquid services
  • Multistage trims also available for cavitation control.
  • Balanced plug construction reduces thrust and actuator sizes
  • Piloted plug construction for tight shut-off up to class V in high temperature services
