High ratio fluid control

A pressure device comprising:

• a cf valve coupled upstream to a solenoid valve;
• and
• a check valve coupled downstream of the solenoid valve;
• wherein the cf valve provides a range of pressures to the solenoid valve.

A dispensing device comprising:

• a syrup unit configured to transmit via one or more orifices at least one or more syrups, one or more gases, and water to a dispensing block;
• a syrup source coupled to the syrup unit configured to provide the one or more syrups to the syrup unit;
• a water source configured to provide the water to at least one of the syrup unit and the dispensing block;
• and
• a cf valve coupled to a first orifice upstream of a solenoid valve, wherein the cf valve is configured to provide a first range of pressures to the solenoid valve, the first orifice is surrounded by a membrane where the membrane includes a nitrogen element where nitrogen is inserted into the water via the membrane;
• wherein the first orifice is coupled to the dispensing block.
