API 6D DN15-DN2000 Class 600 Flanged End Gear Operated High‑Pressure Forged Steel Trunnion‑Mounted Fixed Ball Valve
TIANYU API 6D compliant forged‑steel trunnion‑mounted flanged ball valves represent high‑reliability quarter‑turn shut‑off hardware engineered for severe high‑pressure industrial‑pipeline service. Forged‑A105 pressure‑retaining components eliminate casting‑origin defects, trunnion‑supported ball architecture lowers operating torque and mitigates seat abrasion, while Stellite‑overlay metal‑hard‑seal assembly delivers durable sealing performance under thermal‑cycling and particle‑laden process‑media conditions.
