Electric socket regulating principle of the pneumatic valve

working power supply: ACV V listed such as voltage grade. This kind of pneumatic valves shall generally be installed in the pipeline.
by receiving industrial automation control system of the signal, Such as: ~ mA) Change to drive the pneumatic valve pneumatic valve core and pneumatic 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 inside the elastic element such as a spring, bellows, bellows type bulb, etc. , the principle of balance with the elastic force feedback signal.
indirectly regulating pneumatic valve type, add a command ( The forerunner of pneumatic valve) It play a role of feedback signal amplification and then through the actuator, drive the pneumatic valve pneumatic disc movement to change the purpose of the pneumatic valve opening.
if it is a pressure regulating pneumatic valve, pneumatic valve feedback signal is the outlet pressure, by introducing actuator signal pipe.
if it is a flow control pneumatic valve, pneumatic valve outlet has an orifice ( Or other resistance devices) Introduced by orifice plate ends out differential pressure signal actuators.
if it is temperature control pneumatic valve, pneumatic valve of the export is the temperature sensor ( Temperature or package) Through the temperature sensor in medium heat bilges cold shrink drive actuators.
