  Product details of self operated temperature regulating valve
The self operated temperature regulating valve is mainly composed of control valve and temperature controller
It is an energy-saving product that does not need external energy and depends on the temperature change of the controlled medium for automatic adjustment
It has a wide temperature setting range, clear display, high precision, and is equipped with overload protection device, which is safe and reliable
Therefore, it is widely used in automatic temperature regulation of various heating, water supply, refrigeration, sterilization and other equipment in chemical industry, petroleum, electric power, metallurgy, food, textile, residential buildings, hotels, restaurants and so on

The nominal diameter of this series of products ranges from 20 to 200mm, the nominal pressure ranges from 1
0, 1
6, 4
0 and 6
4Mpa, the operating temperature ranges from -20 ℃ ~350 ℃, and the receiving signal is 0~10ma DC or 4~20ma DC to change the flow of the regulated medium to keep the controlled process parameters at the given value
The single seat regulating type is suitable for occasions with small pressure difference, large medium viscosity or slight particle impurities
The sleeve adjustment type is suitable for occasions with large pressure difference
