The Centurion is a floating pattern ball valve originally designed for a high pressure compressed natural gas application, where the design was substantiated by performing over 1,000,000 cycles. The Centurion design has also been PR2 qualified to API specification 6A, 20th Edition / ISO 10423:2009. Extensive testing and operational experience demonstrate the Centurion valve provides superior sealing solutions where safety and reliability for extended life are required at pressures up to 10,000 psi and a maximum working depth of 3000 metres (10,000 ft).
