Preferable in more demanding applications requiring higher force or redundancy to ensure operational safety and reliability. The tandem configuration can offer enhanced control, especially in environments with high-pressure variations or where backup functionality is critical. It’s suitable for situations where failure of a single actuator could lead to significant downtime or safety concerns, providing an extra layer of security and performance.
Stream-Flo SPDA is supplied either as a full actuator/gate valve assembly or as an actuated bonnet assembly ready to mount on other manufacturers’ valves.
