Self-operated regulating valve is a kind of control valve which relies on the pressure and temperature of the medium inside the valve as energy to drive the valve to work automatically without external power supply and secondary instrument. Self-operated regulating valve use the feedback signals (pressure, differential pressure, temperature) from the output end of the valve to transmit to the actuator to drive the valve disc to change the opening angle of the valve, so as to achieve the purpose of regulating pressure, flow and temperature.
