Design Features:
  • Forged steel body construction secures Class 2500/6000 psi working pressure rating.
  • LF2 valve body & end caps for low-temperature applications.
  • Special design of extended socket weld end facilitates heat dissipation during welding. No prior disassembly of valve is required, therefore welding installation process is shortened.
  • Use of body O-ring and body joint gasket double secures NO LEAKAGE.
  • Live-loaded packing gland for self-adjustment of stem packing compression.
  • Rugged lockable lever handles for safety and long service life.
  • Body O-rings are placed ahead of the body cap threads, providing a tight seal and protection of threads from flow media.
  • Gland bolts allow for easy packing adjustment without handle removal.
  • Pressure equalizing seats & bottom-loaded blow-out proof stems.
  • Vented ball equalizes pressure between the body cavity and the flow stream to prevent seat damage due to thermal cycling.
  • Full compliance with ASME/ANSI B16.34 & EN12516-1.
  • Socket weld ends comply with ANSI B16.11 & EN 12760.
  • Tested according to API 598.
