◆ ZZWP Self-Actuated Temperature Control Valve ( Thermostatic Temperature Control Valve )
Product Description:
The Self Operated Temperature regulating valve is mainly applied in urban heating system and temperature regulating system of automatic control systems in other industries, which may be used for automatic control of temperature of all kinds of heating exchange and cooling devices in an environments with maximal temperature of 350℃and media of non-corrosive liquid, gas and steam. There are two models: that which will close/open when temperature rises.

- Temperature Control Valve is generally applied in the conditions with slow change of temperature other than conditions with intense change of temperature or frequent change of parameters.
- The temperature sensor of T06 executive unit will not directly contact the medium and thus it is convenient for maintenance but with slow response speed, appropriate for controlling liquid media. While the temperature sensor of T17 executive unit will directly contact the medium with a large area for temperature sensing and fast response speed, but inconvenient for maintenance. It’s appropriate for controlling gas temperature, and sometimes for controlling liquid temperature.
Note: The flange sizes in the table are standard sizes subject to GB9113 and ASME B16.5, which may be sizes of other standards such as DIN, JIS.
