Self-acting Temperature Control Valve, DN15-DN200, PN16-PN25

The self-operated temperature control valve utilizes the principle of liquid thermal expansion for automatic adjustment, eliminating the need for an auxiliary actuator. The temperature-sensitive liquid in the sensor expands uniformly in response to temperature changes. This valve regulates the medium's temperature by adjusting the valve opening based on the expansion or contraction of the liquid. When the temperature exceeds the set value, the liquid expands, driving the spool downward to close the valve and reduce the thermal media flow. Conversely, when the temperature falls below the set point, the liquid contracts, and the reset spring pushes the spool open, allowing increased flow. This valve is ideal for applications in heating, air conditioning, domestic hot water systems, petrochemical, electric power, textile, rubber, food, and other industries, offering reliable and efficient temperature regulation without the need for external control mechanisms.For more，know more about China Manufacturers.
