摘要: A pressure proving gas valve (10) insures safe and efficient operation of a fuel-burning appliance by monitoring combustion airflow appropriately controlling the based (22) upon this airflow. An sensor (26) is incorporated into housing (20) itself thus providing integrated solution for control process. Consequently, when heat called for, no fuel provided to chamber (12) unless appropriate air sensed. Further, actual airflow, additional capability provided. That is, variable speed blower (60) associated with apparatus can be controlled provide very precise mixtures.
