    Valve Machine Intelligent Automation
    • Valve Maintenace valve exercisers utilize patented “no assumption” automation technology to safely and effectively turn valves using AWA recommended procedures
    • Protects the operators by keeping 'hands off' the machine while exercising the valve 
    • Protects the valve by not assuming size, direction or current position
    • Allows the machine to follow the path of least resistance 
    • Programming and sensors automatically stop the rotation and reverse in half turn increments to flush calcification from the valve gate
    • Patented automation always exercises valve at the minimum torque required to turn
    • Automation lowers preset threshold once the rotation begins so the impact at the end of valve travel is soft as possible
