  • Transflow valve with an isolation and switching mechanism for double block and bleed arrangement
    Patent number: 9222597
    Abstract: A transfer valve system includes an improved double block and bleed transflow valve system which uses six valves and uses one single spindle interconnecting the inlet and outlet transflow valves, which valves also drive a gear train mechanism connecting all six valve stems. As such, by operating one main spindle connected to the two inlet and outlet transflow valves, all six valves of this double block and bleed configuration operate simultaneously and assure an uninterrupted flow of fluid from one device to another standby device. The transflow valve system also is formed of separable components to form both single and double block and bleed configurations.
