Rotation of a stepper motor controlling a valve mechanism is optically monitored and a feedback signal is sent to the system operator indicating positive operation of the valve only when a selected number of rotations of the stepper motor is reported. The stepper motor may be operated in different modes, each associated with different nominal current consumption levels. In a higher current consumption mode, such as a torque-oriented mode, the stepper motor may be stepped a few additional steps after valve closure to ensure seating of the valve."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gas shut-off valve with feedback","description":"Disclosed are apparatus and methodology for providing a feedback mechanism to a system operator that provides a positive indication of the position of a valve which controls gas flow to a consumer.
