Electric Temperature Control Valve

Electric temperature control valve is a typical application of electric flow control valve in the field of temperature control. Its basic principle is to control the outlet temperature of equipment by controlling the inlet flow of heat exchanger, air conditioning unit or other heat and cold equipment and primary heat ( cold ) medium.  When the load changes, the flow rate is adjusted by changing the valve opening degree to eliminate the influence caused by load fluctuation and restore the temperature to the set value.

Composition of Siemens Temperature Control Valve

Controller:
 Accept the temperature signal and output 0...10V control signal through P/PI/PID operation.  Common models of Siemens controllers include  RWD60 \ RWD 62 \ RWD68 \ RLU36 \ MZ730 - b, etc.
Actuator:
 Accept the adjustment signal sent by the controller, accurately adjust the valve opening, stable operation, optional power-off reset, 3P or analog adjustment, 230DCV or 24DCV power supply.  The common models of Siemens actuators are SUA21\SQS65\SSC85\ SAX61\SKD62\SKB62\SKC62, etc.
Valve body:
 The executor that regulates the flow of medium is matched with the executor to form an electric regulating valve.  Siemens valves are divided into: copper valves, cast iron valves, ductile iron valves, cast steel valves;  According to the connection mode, it can be divided into: threaded connection and flange connection valves;  According to the medium used, it can be divided into water valve and steam valve.  Diameter DN10 ... DN150.(chenxuan  DN15-DN300)
Sensors:
 The temperature of the medium is measured in various types.  According to the installation position, it can be divided into immersion temperature sensor, binding temperature sensor, air duct temperature sensor, indoor temperature sensor, outdoor temperature sensor and other types.

Characteristics of Siemens Temperature Control Valve

 Advantages:

 A. with proportional integral ( PI ) or proportional integral and differential ( PID ) adjustment functions, the control is stable and accurate.
 B, aiming at different field working conditions, the control parameters can be flexibly adjusted to achieve system optimization.
 C, the controller can read the current temperature value and observe the working state of the valve.
 D. Extensible functions, such as remote setting, temperature compensation, overtemperature alarm, heat metering, automatic meter reading, remote transmission, etc.
 E most models can be operated manually when power is cut off.

Features:

 1. Siemens temperature control valve controller is easy to install and debug and does not require expensive debugging and field programming costs.
 2. The controller automatically adjusts the water flow in the primary valve according to the secondary side outlet water temperature to achieve the effects of comfort and energy saving.  The outlet water temperature of the heat exchanger is compensated and changed according to the outdoor temperature, so that users feel comfortable in the use process, and the strange circle that the higher the outdoor temperature is, the higher the indoor temperature is, and the lower the outdoor temperature is, the lower the indoor temperature is is is avoided.  On the premise of comfortable use, users can save operating costs, reduce operating costs and obtain considerable economic benefits.
 3. According to different use sites, especially unattended workstations, the extension function of multi-function controller can be selected to support the control of water pump, flow rate, pressure difference, and alarm for faults in operation.
 4. The valve body adopts advanced pressure feedback device, which solves the problem that the use of electric regulating valve has been affected by high pressure drop for a long time.  It has a wide range of applications, can be used for production and automatic control in various industries such as chemical industry, petroleum, metallurgy, electric power and light industry, and is suitable for heat exchange occasions such as air conditioning, refrigeration, ventilation, heat supply, etc.
 5. Electric valve actuator adopts patented hydraulic control technology of Siemens Building Technology to realize large thrust, long service life, safety and stability, and can effectively save user investment.
 6. Add an outdoor temperature sensor to realize outdoor temperature compensation, which can save energy and reduce operating costs.
