Top Entry Trunnion Ball Valves provide an ideal solution for both offshore and onshore systems. Designed for ease of operation and maintenance, these valves simplify in-line disassembly for trim inspection or internal repairs, even in space-restricted areas.
Our valves offer exceptional corrosion resistance and superior sealing performance across both high and low pressures. Manufactured from a single forged or cast piece, they feature two independent seats for bi-directional sealing. These valves are built to meet customer-specific requirements and comply with international standards.
