It features a proportional integral (PI) or proportional integral derivative (PID) regulation, control and stability, precise. 1, for different site conditions, the flexibility to adjust the control parameters to achieve system optimization. 2, by the controller reads the current temperature value and observe the valve working condition. 3, scalable features such as remote setting, temperature compensation, over-temperature alarm, day and night / winter conversion. 4, valve V-ring sealed with high temperature sealing components and prevent the possibility of stem-lock or leaking. 5, stem or seat lapped to ensure that leakage is far below national standards allow. Intelligent temperature control valve Product Description: Johnson Controls' intelligent temperature control box + intelligent electric actuators combined pressure from balanced body, with precise control, shutdown force, self-balancing anti-lock features. And 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 and responsive, and prolong life. Temperature control box with a PI, PID adjustment function, precise control, multi-loop control, versatile, enabling fluid flow, pressure, pressure, temperature, humidity, enthalpy and air quality control. Smart actuators, adjust the sensitivity, turn off power, flow characteristics adjustable (linear percentage, etc.). May receive a signal 0-10V or 4-20MA and with valve position feedback. Valve flow control valve for chilled water circulation line, low pressure hot water, hot water, high pressure hot water, sea water, hot oil, and steam regulation, good linearity, adjustable ratio, sealed tight, high temperature anti-cavitation.
