Subsea side-entry ball valves are suitable in water depths to 500 mt (1700 fit) and maintain an average service life of 25 years offering the utmost level of reliability and safety under high-pressure conditions even in harsh service with the presence of sand or solid particles.
Subsea side-entry ball valves may be completed with a subsea gear and ROV receptacle for remote operation by a ROV or with a handwheel for manual operation by diver. As an alternative, valves can be fitted with hydraulic subsea actuators, and fully compensated in a double or single acting configuration, with or without ROV override. Subsea side-entry ball valves are available in a wide range of materials and configurations to meet both customer’s requirements and the specific needs of an application
