YZW temperature control valve details

 

 

Product description
The YZW type self regulating temperature regulator needs the external energy to adjust the temperature automatically. It is suitable for various heat exchange occasions such as steam, hot water, hot oil and so on.
Widely used in heating, air conditioning, domestic hot water temperature automatic adjustment, as well as special occasions of automatic temperature adjustment, such as chemical, textile, pharmaceutical and other production projects.
Working principle
Self regulating temperature control valve uses liquid heating expansion and liquid incompressible principle to achieve automatic adjustment. The expansion of the liquid in the temperature sensor is uniform, and its control function is proportional adjustment. When the temperature of the controlled medium changes, the volume of the sensible liquid in the sensor increases with the expansion or contraction. The temperature of the controlled medium is higher than the set value 
When the temperature of the controlled medium is lower than the setting value, the temperature liquid shrinks, the reset spring drives the valve core to open, and the flow of the heat medium is increased.
Applicable scope
Heating, air conditioning, domestic hot water, petrochemical, electric power, mechanical and electrical, textile, rubber, food and other industries.
Use characteristics
1, small size, light weight, easy installation
2, accurate, reliable, long life
3, free maintenance work
4, mediation settings simple
5, passive work (no power, gas source work properly)
6, no expensive debugging costs
7, the valve sealing ring using V type high temperature sealing components, to prevent the possibility of leakage of the valve stem or tight lock.
