Top Entry Trunnion Ball Valves offer an ideal solution for both offshore and onshore systems. Designed for easy operation and maintenance, these valves simplify in-line disassembly for trim inspections or internal repairs, even in space-restricted environments. They provide excellent corrosion resistance and superior sealing performance at both high and low pressures. Constructed from a single forged or cast piece, the valves feature two independent seats for bi-directional sealing and are manufactured according to customer specifications and international standards.
