• 2-piece cast flanged valve • Double block & bleed • Blowout-proof robust stem design • Bi-directional as standard • API 6D certified (API monogram #6D-1278) • Fire safe designed to API 6FA, API 607, ISO 10497 • Comply with NACE MR0175/ISO 15156 • Corrosion resistant low friction bearings • Double Piston Effect or Single Piston Effect seat design • Mixed SPE and DPE seats design also available • Inconel springs, assist in low pressure sealing 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.
