Working power supply: AC22V 380 v voltage grade, etc. This valve shall generally be installed in the pipeline. By receiving industrial automation control system of the signal, Such as: 4 ~ 20 ma) To drive change valve core and valve seat between the cross-sectional area of the pipeline medium size control of process parameters such as flow rate, temperature, pressure and etc. Automated regulating function. Direct action type is also known as the spring load type, the structure with elastic element such as a spring, bellows, bellows type bulb, etc. , the principle of balance with the elastic force feedback signal. Indirect acting regulator, add a command ( Pilot valve) It play a role of feedback signal amplification and then through the actuator, drive the main Industrial Valves disc movement to achieve the purpose of the change of valve opening. If it is a pressure regulator, feedback signal is the valve outlet pressure, by introducing actuator signal pipe. If it is a flow control valve, the valve outlet has an orifice ( Or other resistance devices) Introduced by orifice plate ends out differential pressure signal actuators. If the temperature regulating valve, Industrial Valves of the export is the temperature sensor ( Temperature or package) Through the temperature sensor in medium heat bilges cold shrink drive actuators.
