Abstract

A breathing assistance device includes a gas regulating valve (1300). The gas regulating valve is operated by a linear actuator (1330). The linear actuator may include a movable member that moves an obstruction member between an open position and a closed position. The linear actuator is isolated from a gas flow path through the valve.
