Control valves, series LTG1 and LTG2

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 simple construction and to the large range of available materials these valves are suitable for a wide range of applications, also for corrosive, dirty, sticking and slightly abrasive fluids.

Control valves

Angle-body special design is also available for LTG1 and LTG2 control valves.

Actuators:

  • pneumatic either piston or diaphragm types
  • electric actuator available also for control service

Body:

  • flanged, butt-welded, SW, and threaded
  • cast construction, also wrought or by bar for smaller dimensions
  • face-to-face dimensions as per IEC 60534-3-1

Sizes:

  • 3/4", 1", 1-1/2", 2", 3", 4", 6" and ratings up to ANSI600 / PN100

Materials:

  • carbon, Cr-Mo and AISI 316 stainless steel

Flow direction:

  • to open
  • to-close direction is also allowed for cavitating-not-flashing liquids, provided the internal plug balancing is guaranteed to avoid negative gradients

Trim:

  • Top guided unbalanced plug both in LTG1 and LTG2 constructions

Guide:

  • a bush fitted into the bonnet
  • linear and equil% up to 2" port included - modified linear for higher sizes

Available plug types:

  • contoured
  • flat disc for quick opening operation
  • skirted and drilled BRD design (linear characteristic) for special services
  • soft seat - only for contoured and flat disc.
