The ZZWP type self-operated temperature regulating valve utilizes changes in the temperature of the medium being regulated to perform adjustments. Its temperature regulation range is from 20°C to 100°C, featuring a relatively wide temperature setting range and over-temperature overload protection measures. The temperature setting is convenient; a temperature scale plate is used for setting, and continuous adjustments can be made during operation.

It is widely applied in industrial sectors such as petroleum, chemicals, printing and dyeing, and pharmaceuticals, as well as in urban heating and heat supply systems
