An addressable valve system is described wherein a plurality of valves are embedded into a single, compact valve block. Each valve comprises a piston moving in a bore in the block. A magnet embedded in the piston is positioned within a coil. When energized, the coil attracts the magnet and the plunger upwards away from a valve seat. Magnetic shields disposed between the pistons provide magnetic isolation between the pistons and simultaneously apply a closing force to the pistons by drawing the magnets downward towards the valve seat. When energized, the coils overwhelm the closing force and open the valves. Electronics for the valve block and the coils are provided on a circuit board overlying the pistons and bores. The electronics provide addressability of the valves and automatically generate "pick" and "hold" timing whereby the initial motivating force (voltage) applied to the current is higher to get the valves moving quickly when valve is first commanded to open. After a brief period of time, the coil voltage is lowered to a level that provided a lower maintaining force to keep the valve open.
