Product Overview

The major characteristic of self-operated electronic control temperature control valve is that it realizes directly automatic adjustment and control of temperatures of many mediums such as steam, hot water, hot oil, and gas through using heat of mediums with requirement of 220V power supply. What’s more, it can be used in the circumstance that overheating and heat exchange should be prevented. Because of its simple structure, easy operation, wide selected temperature range, fast response time, and reliable sealing property as well as being optionally adjusted in service, it is widely used to provide hot water for many departments including chemical engineering, petroleum, food, light textile, hotel, and restaurant.

Product Features

Temperature control system can be automatically formed as long as using single-phase alternating current power supply AC220V and temperature sensor on the site.
FDY-258T temperature control module of high integration in actuator succeeds in uniting temperature controller and actuator as one, realizing electromechanical integration and simplifying temperature control system.
It has the features of high control accuracy, rapid response speed, stable and reliable property, and long working life.
Possessed of broad subject range, it has the ability to conduct temperature control in an extremely wide temperature range.
It is characterized by compact structure, easy installation and debugging, and simple usage.
