Abstract
A liquid flow control solenoid valve for a beverage dispensing system wherein a rolling diaphragm seal is used between a needle valve and the valve body and the increased hydraulic forces on the needle valve caused by the rolling diaphragm are balanced by using a needle valve that is tapered in a direction to create a force on the needle valve in the direction opposite to the force created by the rolling diaphragm, so that the hydraulic forces are balanced and a smaller solenoid can be used to operate the valve.
