Heating type temperature control valve is a kind of driving without external energy, depending on the medium itself was transferred energy as power source and medium temperature change, according to a predetermined set value for energy-saving automatic control device. It sets the detection, control and execution of many functions in a valve, since the instrument control system.

Structural 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. Because the product without external energy, has the advantages of simple structure, convenient use, less maintenance workload, especially suitable for city heating, heating and power supply, gas supply and no need to control the liquid and gas. According to foreign reports, city heating, heating system uses the energy saving products, improve the efficiency of 30%-40% has significant effect than before.
