Subsea fully welded ball valves are suitable in water depths to 500 mt (1700 fit) and maintain an average service life of 25 years. Valves are designed with two or three fully welded forged pieces with a solid double trunnion configuration and two independent seats with bidirectional sealing ensuring the greatest level of tightness and reliability under high pressure and temperature conditions in all critical isolation services. The fully welded body construction ensures a lighter solution and avoids potential leak paths to the external environment. As a result, the valves are an excellent choice in marine and subsea pipelines. Subsea fully welded trunnion ball valves may be completed with a subsea gear and ROV receptacle for remote operation by ROV or with a handwheel for manual operation by the diver. As an alternative, valves can be fitted with hydraulic subsea actuators, fully compensated in a double or single acting configuration, with or without ROV override.
