ABSTRACT:
A remotely contollable, motorized valve suitable for microprocessor control. The valve is protected against over-closure by a technique of current sensing of motor current. Starting surges are ignored through the use of a timing circuit. The valve may be re-started in the event of mid-travel stoppage, but is still protected against damage due to such stoppage, by permitting manual reset after the valve is stopped.
