Overall dimensions of this package are 2.5 cm x 3.0 cm x 1.0 cm. If current is too small, the valve will not open. If too much current flows through the actuator it will overheat and be damaged. The liquid valve membrane opens in approximately 1 sec. A typical flow rate with aqueous solutions is between 5 and 7 ml per min.
Leak rate is too small to be measured with available equipment.
