In one embodiment, a fluid dynamics system includes a solenoid valve including a valve body including ports including an inlet and outlet port, and a valve cavity having a direction of elongation and configured to provide fluid connectivity between ones of the ports, a solenoid coil disposed around valve cavity, and a plunger including a permanent magnet, and configured to move back-and-forth along the direction of elongation between a first and a second position in the valve cavity selectively controlling the fluid connectivity between respective ones of the ports, the valve body including shock absorber(s) to soften striking of the plunger against the valve body in the direction of elongation, and a controller configured to apply at least one current to the solenoid coil to selectively move the plunger between the first and second position, and to selectively maintain the plunger in the first position and the second position.
