A self-operated control valve, also known as a self operated pressure control valve or self operated temperature 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 operated control valve to work automatically and does not require an external power supply and secondary instrumentation.
