The Subsea Trunnion Mounted Ball Valve is a quarter-turn ball valve designed for total reliability against internal and external leaks in shallow and deep-water applications. Features and benefits: - Application flexibility derived from compatibility with hydraulic actuators, ROV-operated gear boxes, and electrical and hydraulic umbilical systems - Extended life due to robust design that protects against leaks with metal-to-metal seats, elastomeric and thermoplastic seals, and corrosion-resistant alloy seal housing - Minimized leak paths made possible by body designs plus corrosion-resistant materials of construction - Complete safety and functionality compliance ensured by hyperbaric chamber testing (API 6DSS certification/API Spec Q1)
