Types of temperature control valves
Thread Content
Everyone, while researching, I came across that thermostatic valves come in KT types as well as non-KT types. I would like to know what KT means. What are the different types of thermostatic valves?
Working principle of the YZW type self-acting temperature control valve: The self-acting temperature control valve achieves automatic regulation by utilizing the principles of thermal expansion of liquids and the incompressibility of liquids. The expansion of the liquid inside the temperature sensor is uniform, and its control mechanism operates on a proportional basis; as the temperature of the medium being controlled changes, the volume of the temperature-sensing liquid inside the sensor expands or contracts accordingly. When the temperature of the medium under control exceeds the set value, the temperature-sensitive liquid expands, pushing the valve core downward to close the valve and reduce the flow rate of the heat transfer fluid ； When the temperature of the medium under control is below the set value, the temperature-sensitive fluid contracts, and the return spring pushes the valve core open to increase the flow rate of the heat transfer medium.
A temperature control valve, also simply referred to as a temp control valve, is a typical application of flow control valves in the field of temperature control. Its basic principle is to control the outlet temperature of a device by regulating the flow rate of the heat transfer fluid, air conditioning unit, or other equipment that uses heat or cold, at the inlet of such fluids. When the load changes, the flow rate is adjusted by changing the valve opening degree in order to eliminate the effects of these load fluctuations and restore the temperature to the set value. Thermostatic valves can generally be divided into: self-acting thermostatic valves, electric thermostatic valves, and radiator constant temperature control valves
