ABSTRACT:
An automatic temperature responsive control valve is disclosed for use in combination heating and cooling systems including two concentric valve sleeves each rotating individually in the valve body under the control of respective bimetallic transducers one of which directs work fluid to either a heating heat exchanger or a cooling heat exchanger in accordance with the temperature of work fluid supplied to the valve by either a chiller or a boiler through a solenoid valve controlled by the outside temperature and the other of which provides modulated flow through the heating or cooling means under the control of the spent fluid temperature. The control valve is usable for controlling the temperature of one or more rooms or for similar control of a process vessel so as to provide unique versatility of use.
