Top-entry trunnion ball valves are the perfect solution for both offshore and onshore systems. Convenience of operation and maintenance are essential features of our design simplifying in-line disassembly for trim inspection or internal repairs even where space is restrictive. Our valves also offer excellent corrosion resistance and superior sealing performance at both high and low pressures. Valves are manufactured in a single forged or cast piece and configured with two independent seats for a bi-directional sealing and are manufactured in accordance with customer specific requirements and international standards.
