LTG1 and LTG2 Control Valves

About this product

Globe straight-way, single seat LTG1 and LTG2 series are very versatile control valves of general use for any applications under moderate p/T service conditions. LTG1 is the standard design with screwed seat ring while LTG2 is the corresponding quick-change version with the same flow coefficients and pressure differentials capability. Due to their simple construction and to their large range of available materials these valves are suitable for a wide range of applications, such asr corrosive, dirty, sticking and slightly abrasive fluids. Angle-body LTA special design is also available with the same trims of LTG series. Main advantages: • Excellent plug stability provided by heavy top guiding design • Interchangeable low noise and anticavitation trim either for std or quick-change design • Tight shut-off class V and VI also available • Wide flow range capability is allowed by a great number of reduced capacity trims LTG2 ANSI 300 Diaphgram Actuator Technical characteristics: Seat Ring: • Threaded in LTG1 model and clamped-in in LTG2 model Leakage Class (IEC 60534-4): • Standard: class IV • Optional: class V and VI Actuators: • Pneumatic diaphragm or Piston type • Electric and Electro-Hydraulic actuators LTA design Globe types LTG1 and LTG2 are also available with angle body. In this case they are designated as LTA1 and LTA2 Control Valves. LTA series are special engineered designs. The advantages provided by LTA series are the following: 1 - Different dimensions for valve inlet and outlet are available 2 - Inlet and outlet ratings can also be different 3 - Centre-to-face dimensions consistent with IEC standard when the connections have the same dimensions 4 - Increased Cv values in comparison with LTG1 and LTG2 standard body style due to less pressure drop of angle path 5 - Trims, characteristics, material and actuators are the same of standard LTG series Standard contoured plug LTG1 Std contoured plug LTG2 Std contoured plug LTG1 ANSI 600 Electric Actuator
