Product Description

YZWThe self operated temperature regulating valve can automatically adjust the temperature without the need for external energy. It is suitable for various heat exchange occasions using steam, hot water, hot oil and other media. Widely used for temperature automatic regulation in heating, air conditioning, domestic hot water, and special occasions such as chemical, textile, pharmaceutical and other production engineering.

working principle

The self operated temperature regulating valve utilizes the principle of liquid thermal expansion and incompressibility to achieve automatic regulation. The liquid expansion inside the temperature sensor is uniform, and its control function is proportional adjustment. When the temperature of the controlled medium changes, the volume of the temperature sensing liquid inside the sensor expands or contracts. When the temperature of the controlled medium is higher than the set value, the temperature sensing liquid expands, pushing the valve core downwards to close the valve and reduce the flow rate of the heat medium; When the temperature of the controlled medium is lower than the set value, the temperature sensing liquid contracts, and the reset spring pushes the valve core to open, increasing the flow rate of the heat medium.

Scope of application

Industries such as heating and air conditioning, domestic hot water, petrochemicals, electricity, electromechanical, textile, rubber, food, etc.

Scope of application
