SPDA-T Tandem Actuator

Precision Engineered for Optimal Performance

Dual strength for demaning applications

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.
