Top Entry Trunnion Ball Valves are the perfect solution for both offshore and onshore systems. These valves are designed with convenience of operation and maintenance in mind, simplifying in-line disassembly for trim inspection or internal repairs, even in restrictive spaces. They offer excellent corrosion resistance and superior sealing performance at both high and low pressures. Manufactured in a single forged or cast piece, these valves are configured with two independent seats for bi-directional sealing. They are produced in accordance with customer-specific requirements and international standards.
