LTG3 Cage Control Valves

About this product

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 LTG3 20" ANSI 900 LTA design LTG3 are also available with angle body. In this case they are designated as LTA3 Control Valves. LTA series are special engineered designs. The advantages provided by LTA design are the same of LTA1 series. Technical characteristics: Seat Ring: • Quick-change and free-expanding type, precisely coupled to the cage to ensure a perfect plug alignment Leakage Class: • Classes III, IV, IV S1 and V according to IEC 60534-4 Class VI is also available with soft-seat Actuators: • Pneumatic diaphragm or Piston type • Electric and Electro-Hydraulic actuators LTG3 plug with soft insert Single stage Low noise cage MPS trim balanced plug Double stage balanced plug Low noise cage construction LTG3 - cage assembling LTG3 - control valve under cryogenic test
