The regulating valve is also called a control valve, and in the field of automatic heat supply process control, the final control element for changing the process parameters of medium flow, pressure, temperature, liquid level and the like by power operation through receiving the control signal output by the regulating control unit. Generally consisting of an actuator and a valve. If according to the stroke characteristic, the regulating valve can be divided into a straight stroke and an angular stroke; the power used by the matched actuating mechanism is divided into three types, namely linear characteristic, equal percentage characteristic and parabolic characteristic according to the function and the characteristic.

The regulating valve acts as a variable resistance in the conduit. It changes the turbulence of the process fluid or provides a pressure drop in laminar flow conditions, which is caused by changing the valve resistance or "friction". This pressure reduction process is commonly referred to as "throttling". For gases, which are close to isothermal adiabatic conditions, the deviation depends on the non-ideality of the gas (joule-thomson effect). In the case of liquids, the pressure is then dissipated by turbulent or viscous friction, both of which convert the pressure into heat energy, resulting in a slight increase in temperature.

The regulating valve is used for regulating the flow, pressure and liquid level of the medium.
