Widely used in heating and heating, refrigeration and air conditioning, domestic hot water, petrochemical, power, electromechanical, textile, rubber, food and other industries.

The self-operated temperature control valve automatically regulates temperature without external energy. It is suitable for various heat exchange conditions with steam, hot water, thermal oil, etc. as the medium. Widely used for automatic temperature regulation in heating, air conditioning, and domestic hot water, as well as for automatic temperature regulation in special working conditions, such as chemical, textile, pharmaceutical production processes.

Working principle: The self-operated temperature control valve utilizes the principle of thermal expansion of liquid and the incompressibility of liquid to achieve automatic regulation. The liquid expansion in the temperature sensor is uniform, and its control action is proportional regulation. When the temperature of the controlled medium changes, the volume of the temperature-sensitive liquid in the sensor expands or contracts accordingly. When the temperature of the controlled medium is higher than the set value, the temperature-sensitive liquid expands, pushing the valve core downward to close the valve and reduce the flow of the heating medium; when the temperature of the controlled medium is lower than the set value, the temperature-sensitive liquid contracts, and the return spring pushes the valve core to open, increasing the flow of the heating medium.

Usage characteristics: 1. Simple installation. 2. No need for power or air source. 3. Easy adjustment and setting. 4. Balanced valve core design.
