Top Entry Trunnion Ball Valves are ideal for both offshore and onshore systems, offering ease of operation and maintenance. The design allows for simplified in-line disassembly, making trim inspection or internal repairs straightforward, even in confined spaces. These valves provide excellent corrosion resistance and superior sealing performance at both high and low pressures. Manufactured from a single forged or cast piece, the valves are configured with two independent seats for bi-directional sealing. They are produced in accordance with customer-specific requirements and meet international standards for reliability and performance.
