    Actuation Solutions

    Stream-Flo’s Crown self-contained hydraulic valve actuation system is used for the automatic closing of valves on wellheads and flow lines under emergency conditions. The system consists of a hydraulic actuator, a manual hydraulic pump and control assembly attached to a linear or rotary valve.

    Pneumatic actuators are simple to maintain and offer reliable operation, ensuring a product life cycle with minimal equipment related downtime.   

    ESD-EH uses our PwrESD system which is an integrated electro-hydraulic power unit designed to operate hydraulic actuators for surface safety valves (SSVs) and flow-line ESD valves.

    Powered by SmartVue™ for data acquisition, local user interface, and edge computing to run condition monitoring and autonomous operations. The controller can be offered as an explosion-proof / flameproof Class 1 Division 1/Zone1 or Class 1 Division 2/Zone2 solution.

    Electric-powered actuation solutions for on-off fail in place applications.
