Force type temperature regulating valve is mainly composed of a control valve and a temperature controller, is a need of external energy and rely on controlled temperature change of the medium of the automatic adjustment of energy saving products. There is a wide temperature range, clear display, high precision, and is equipped with overload protection device, safe and reliable, and automatic regulation is widely used in chemical, petroleum, electric power, metallurgy, textile, food, hotel, hotel, residential building blocks such as water supply, heating, refrigeration, disinfection and sterilization equipment temperature.

This series of products of nominal diameter from 20 to 200mm, 1, 1.6, nominal pressure 4 6.4MPa, the temperature range of ~350 DEG C by -20, 0~10mA.DC or 4~20mA.DC to accept the signal change by adjusting the media flow, make the controlled parameters to maintain a given value, the single seat control type suitable for low pressure difference, medium high viscosity or slightly granular impurities occasions. The sleeve type is suitable for adjusting pressure situations.
