Siemens temperature control valve is controlled by the heat exchanger, air conditioning unit or other hot and cold equipment, primary heat (cold) medium inlet flow to achieve control equipment outlet temperature. When the load changes, the flow rate is adjusted by changing the valve opening degree to eliminate the influence of the load fluctuation and return the temperature to the set value. Compared with other temperature control valves, Siemens temperature control valves have the following five advantages: 1. It has proportional integral (PI) or proportional integral and differential (PID) adjustment functions, and the control is stable and accurate. 2. For different on-site conditions, the control parameters can be flexibly adjusted to achieve system optimization. 3. The current temperature value can be read by the controller and the working state of the valve can be observed. 4, expandable functions, such as remote settings, temperature compensation, over temperature alarm, heat metering and automatic meter reading, remote transmission and so on. 5. Most models can be manually operated during power failure. |
