Our top-entry trunnion ball valves are ideal for both offshore and onshore systems. Designed for ease of operation and maintenance, these valves allow for in-line disassembly, making trim inspection or internal repairs simple, even in space-restricted areas. They offer outstanding corrosion resistance and excellent sealing performance at both high and low pressures. Manufactured as a single forged or cast piece, the valves feature two independent seats for bi-directional sealing and are built to meet customer-specific requirements and international standards.
