Top Entry Trunnion Ball Valves are engineered for both offshore and onshore applications, delivering exceptional performance in terms of operation, maintenance, and durability. Their design simplifies in-line disassembly, making it easy to inspect or repair valve trim, even in space-restricted environments. These valves offer excellent corrosion resistance, superior sealing performance, and are capable of handling both high and low-pressure conditions. Manufactured as a single forged or cast piece, these valves feature two independent seats for bi-directional sealing and are custom-built to meet specific customer requirements while adhering to international standards.
