High Temperature Trunnion Ball Valve

Materials:

  • Stainless Steel, alloys, Carbon Steel – selected to meet temperature and application. ASME
    B16.34 listed cast or forged material for the valve body and ends.
  • Surface treatments & coatings – LTPN, HVOF Cr₃ C₂ (Chromium Carbide), HVOF WC-Co
    (Tungsten Carbide) and Stellite.

Robust design:

  • Pressure containing parts are in compliance with ASME B16.34 (with modifications for
    some series).
  • Leak rate to EN12266-1 Rate B (factory tested) is achieved by accurate grinding and
    lapping processes.
  • Constant preloading of ball/seats set obtained by Inconel 718 Belleville spring.

Pressure tested:

  • Designs are burst proof tested for 4 times the maximal working pressure.
  • Designed and tested per testing & acceptance criteria ANSI/FCI 70-2.
