Operation: Pneumatic Actuator

Top entry trunnion ball valves are the ideal solution for both offshore and onshore systems. Designed for convenience in operation and maintenance, these valves simplify in-line disassembly for trim inspection or internal repairs, even in space-restricted areas. They offer excellent corrosion resistance and superior sealing performance under both high and low pressures. Manufactured as a single forged or cast piece, the valves are configured with two independent seats for bi-directional sealing. These valves are produced according to customer-specific requirements and international standards.
