A self operated control valve, also known as a self actuated temperature control valve or self actuated pressure control valve, is an auto control valve that relies on the pressure and temperature
of the medium flowing through the valve as an energy source to drive the self actuated valve to work automatically and does not require an external power supply and secondary instrumentation.
