Technology Transfer Brings New Life to Electric Control Valve Actuation


The limitations of traditional electric actuators have an impact on the life of the system. The most common problem is exceeding the rated duty cycle, causing the motor to burn out. A study done by ExxonMobil and presented in October 2012 at Coking.Com identified wear issues. Download this white paper to learn more.

Electric actuators have long been used for general valve automation. When applied to control valves, however, limitations inherent with traditional electric technology preclude its effective use for modulation control, especially when fast response is required. Servo motor control and roller screw technology, both used for years in the motion control industry, do not suffer from the same limitations and can therefore offer a highly responsive, robust and accurate electric solution that is well suited for demanding valve control applications.
