Release time:2023-11-03 Click:


Subsea ball valves are mainly used in Subsea manifolds, submarine pipeline terminals and oil and gas transmission pipelines of offshore oil and gas projects. The sealing structure of the valve adopts the sealing form of single piston effect (SPE) + double piston effect (DPE) combination, and the SPE is set to seal the upstream of the valve, which can realize the function of automatic discharge of overpressure in the valve cavity to the upstream. The operation mode of submarine valves mainly includes hydraulic control, remote control operation (ROV) and diver operation. The service life of Subsea ball valves is required to be long, generally more than 30 years.
