Instructions for Use
Self-actuated electric temperature control valve (suitable for larger pipe diameters and heat transfer oil control), this valve has the following main features: It only requires ordinary 220V power supply, and uses the energy of the medium being regulated to directly control and regulate the temperature of steam, hot air, hot oil, and gases, etc. It can also be used to prevent overheating or heat exchange occasions. The valve has a simple structure, convenient operation, a wide range of temperature control, fast response time, reliable sealing performance, and can be adjusted at will during operation, thus it is widely used in hot water supply in chemical, petroleum, food, light textile, hotels and restaurants and other departments.
Product Features
The nominal diameter of this product series ranges from 20 to 200mm, the nominal pressure is 1.0, 1.6, 4.0, 6.4MPa, the operating temperature range is from -20℃ to 350℃, and the accepted signal is 0~10mA.DC or 4~20mA.DC to change the flow rate of the medium being regulated, so that the controlled process parameters remain at the set value. Among them, the single-seat control type is suitable for occasions with small pressure difference, large medium viscosity, or slight particle impurities. The sleeve control type is suitable for occasions with large pressure difference.
