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.
