  • Two piece full bore design, flanged construction in carbon steel, stainless steel and special alloys.
  • Designed in accordance with ASME B16.34, BS EN ISO 17292 & ISO 14313/API 6D.
  • Floating ball design for bi-directional shut-off.
  • Flexing soft seat design for superior shut-off across a range of pressures with minimum operating torque.
  • Low temperature and cryogenic designs for service down to -196°C available on request.
  • Spring energized metal and carbon seat designs permitting tight shut-off and positive cavity pressure relief.
  • Fused hard nickel alloy, chromium carbide or tungsten carbide coated seat and ball designs for abrasive and high temperature service.
  • Hard carbon seat design for medium temperature applications.
  • High integrity shaft seal minimizing the potential for atmospheric leakage.
  • Fugitive emission performance to BS EN ISO 15848-2 class A.
  • Corrosion resistant trim. Standard valves incorporate balls and shafts of stainless steel for long service life.
  • Fire test certified. All sizes and pressure ratings are covered by approved certification.
