Siemens chilled water with an electric two-way valve - Siemens three-way valve - China's total generation ..

Siemens chilled water with an electric two-way valve - Siemens three-way valve - China agent - Shanghai Sales First, the basic principles of electric thermostatic valve flow control valve is a typical application in the field of temperature control, the basic principle: by controlling the exchange heat, air conditioning units or other hot, cold equipment, a hot (cold) medium inlet flow, in order to control the device outlet temperature. When the load is changed and by changing the valve opening degree adjusting flow, to eliminate the effect of load fluctuations caused by the temperature returns to the set value. Second, the Product Overview 1, Siemens electric thermostatic valve: (1) Introduction Our company is Germany's Siemens Building Technologies products authorized agents, to provide Siemens imported electric valve, the product uses Siemens original temperature sensor, temperature controller electric actuators and valves, according to the use of different equipment on-site system flexibility to adjust the proportional band, integral time and other parameters to best match the system may eliminate static error, stable, responsive, high precision temperature control, long service life. (2) Advantages: a, with a proportional-integral (PI) or proportional integral derivative (PID) regulation, control and stability, precise. b, for different site conditions, the flexibility to adjust the control parameters to achieve system optimization. c, by the controller reads the current temperature value and observe the valve working condition. d, scalable features such as remote setting, temperature compensation, over-temperature alarm, with heat metering and automatic meter reading, remote and so on. e, most models can be manually operated during a power outage. This product can be expanded common functions are: - Outdoor temperature compensation (according to outdoor temperature changes, automatically adjust the water temperature energy-saving and comfortable.); - Over-temperature alarm (safety); - sub-time control (depending on time of the controller setpoint , at different times to automatically adjust water temperature saving); - fans, pumps linkage; - Winter / summer operation mode automatic conversion; - remote set; -PI limit (dual regulation, energy, security); - limiting valve stroke bit (set the maximum valve opening and the smallest opening, the default 100% / 0%), etc.
