Heating type self regulating temperature control valve is a kind of energy saving control device without external driving energy, depending on the heat of the medium itself as the power source and the temperature change of the medium, according to the preset setting value. It has many functions, such as detecting, controlling and executing. It is a self-contained control system.

Structure characteristics

The product is composed of low flow resistance (single seat valve, sleeve) composition, temperature and equilibrium temperature setting mechanism, its characteristics are: 1, without additional energy saving control system of power equipment, low cost, suitable for explosive environment; 2, simple structure, small maintenance workload, set point can be 3; adjustable wide range, convenient for the user to adjust continuously in the range of set value; 4, a temperature overload protection device, safe and reliable; the pressure balancing mechanism 5, the valve, the valve is sensitive and accurate control, allowing a large pressure difference. The product has the advantages of simple structure, convenient use, less maintenance work, etc. because of no need of external energy, it is especially suitable for urban heating, heating, and without power supply, gas supply and the need to control liquid and gas occasions. According to foreign reports, the city heating, heating system using the product, energy efficiency improved 30%-40% than before, the effect is remarkable.
