• Otis- Axelson Hydraulic Self-Contained Safety System

    Our Otis-Axelson Hydraulic Self-Contained Safety System is a highly reliable single shutdown valve or single surface safety valve (SSV) controller designed specifically for remote locations where external power sources are not available.

    Completely self-contained, the system only requires that the operator manually pump up the hydraulic system to put the safety system in service. The system remains in service until an event triggers the shutdown sequence. The system’s key safety features including a high- and low-pressure shutdown function, a high-temperature shutdown function, and an emergency shutdown function.
    Description

    The system is completely self-contained and only requires that the operator manually pump up the hydraulic system to put the safety system in service, opening the valve and arming the Otis-Axelson High Flow ESP hydraulic pressure sensors.

    When the system is put in service, the valve remains open until an event triggers the shutdown sequence in the system. The shutdown sequence ends with the AUH actuator failing to the safe position.
