Abstract: A fluid or gas delivery system is provided for controlling fluid or gas temperature, flow rate and volume at a system outlet. The system comprises single or double control valves for regulating flow of a first fluid or gas and a second fluid or gas from corresponding first and second fluid or gas sources into a mixing port, wherein the first fluid or gas has a different temperature from the second fluid or gas. A fluid or gas supply control valve actuator operatively connected to the first and second fluid or gas supply valves actuate opening and closure operations of the valves. A thermosensor thermally coupled with the mixing port senses an estimated present temperature of a mixed fluid or gas within the mixing port. A flow control valve regulates flow of a mixed fluid or gas at the system outlet. A flow control valve actuator operatively connected to the flow control valve actuates opening and closure thereof.
