Abstract

A circuit arrangement to control at least one valve includes at least one actuator with at least one positioning element adjustable between at least one first position and a second position. At least one driver unit activates the actuator and a control unit operates the driver unit. At least one air mass measuring device measures an air mass flowing through the valve. The control unit processes an output signal of the air mass measuring device. Valves, valve arrangements, seat comfort systems, and methods all use such circuit arrangements.
