Product details

Electric temperature control valve is an intelligent valve that integrates components such as electric actuators, sensors, and controllers. Can be used in conjunction with gate valve, pressure reducing valve, butterfly valve, etc. It is mainly used to achieve precise temperature control by adjusting the flow rate of the medium. This type of valve is widely used in heating, cooling, industrial processes, and other fields, especially in situations where precise control of the temperature of gases, liquids, vapors, and other media is required to maintain a given value.

working principle

The electric temperature control valve is mainly composed of a temperature sensor, a controller, an electric actuator, and a feedback system. The temperature sensor is responsible for sensing the temperature of the medium and converting the temperature signal into an electrical signal; The controller receives sensor signals and outputs control signals based on the difference between the set value and the actual value; The electric actuator receives control signals, drives the valve core to move, changes the medium flow rate, and thereby adjusts the temperature; The feedback system monitors the position of the valve core and feeds back the actual flow signal to the controller, forming a closed-loop control system.

advantage

Accurate control: With proportional integral (PI) or proportional integral derivative (PID) adjustment functions, the control is stable and precise.The following is composed of a stainless steel structure globe valve.
Versatile functions: capable of controlling fluid flow rate, pressure, pressure difference, temperature, humidity, enthalpy value, and air quality.
Adjustment sensitivity: The actuator has sensitive adjustment, large shut-off force, and adjustable flow characteristics (such as linear, equal percentage, etc.).
Scalability: Scalable functions such as remote settings, temperature compensation, over temperature alarm, heat metering and automatic meter reading, remote transmission, etc.
Manual operation: Most models can be manually operated when power is off.

application

Electric temperature control valves are widely used for hot water supply in chemical, petroleum, food, textile, hotel and restaurant sectors, as well as thermal power systems in thermal power plants and heat exchange stations, petrochemical, textile, printing and dyeing, food, medicine, papermaking and other thermal power systems
