Siemens electric temperature control valves are widely used in urban heating, gas supply, air conditioning, refrigeration and other building automatic control systems. Also suitable for chemical, petroleum, metallurgy, electric power, food and other industries production process automatic control system.
Germany Siemens original controller and electric actuator, combined with the pressure self-balancing valve body provided by our company, with accurate control, large closing force, self-balancing anti-lock and other characteristics. And according to the use of the field system equipment can flexibly adjust the proportion of the belt, integration time and other parameters, so that it can match the system, can eliminate static difference, smooth operation, sensitive response, extend the service life. The controller has PI and PID adjustment functions, accurate control, multi-loop control, and various functions, which can realize the control of fluid flow, pressure, pressure difference, temperature, humidity, enthalpy value and air quality. The actuator has electromechanical and electrohydraulic, with manual and automatic adjustment functions, sensitive adjustment, large turn-off force, and adjustable flow characteristics (linear percentage). Electrohydraulic actuator with power off automatic reset protection function, can receive 0-10V or 4-20MA signal with valve position feedback function.
The flow control valve of the valve body is suitable for circulation pipeline chilled water, low pressure hot water, domestic hot water, high pressure hot water, seawater, hot oil, and steam regulation, good linearity, adjustable ratio, tight seal, high temperature resistance, anti-cavitation.
First, product characteristics
It has the function of proportional integral (PI) or proportional integral and differential (PID) adjustment, and the control is stable and accurate.
a. According to different field conditions, the control parameters can be flexibly adjusted to achieve system optimization.
b. The controller can read the current temperature value and observe the working state of the valve.
c. Extensible functions, such as remote setting, temperature compensation, overtemperature forecast, day/night/winter/summer conversion.
D. The valve body is sealed with V-ring high-temperature sealing assembly to prevent the possibility of valve stem death or leakage.
e. Stem or seat pair grinding, to ensure that the leakage is far below the national allowable standards.
