Hebei Jiuyun Electric Three way Temperature Control ValveIt is a typical application in temperature control fields such as HVAC. The controller has PI and PID regulation functions, accurate control, multi loop control, diverse functions, and can achieve control of fluid flow rate, pressure, pressure difference, temperature, humidity, enthalpy value, and air quality. The actuator has electric mechanical and electric hydraulic types, with manual and automatic adjustment functions, sensitive adjustment, large shut-off force, and adjustable flow characteristics (linear percentage). Electric hydraulic actuator with power-off automatic reset protection function, can receive 0-10V or 4-20mA signals and has valve position feedback function. The valve body is a flow regulating valve, suitable for regulating chilled water, low-pressure hot water, domestic hot water, high-pressure hot water, seawater, hot oil, and steam in circulation pipelines. It has good linearity, large adjustability, tight sealing, high temperature resistance, and anti cavitation
