Electric pneumatic valve and electromagnetic what are the differences between the structure of the pneumatic valve and usage

hydraulic solenoid pneumatic valve is produced using an electromagnetic coil magnetic absorption to control the pressure of the spring drive the pneumatic valve core movement; Electric pneumatic valve is a motor driven by pneumatic valve stem, drive the pneumatic valve core movement, the electric pneumatic valve, close to snuff out pneumatic valve and control valve.


the difference between the electric pneumatic valve and solenoid pneumatic valve:


solenoid pneumatic valve is produced using an electromagnetic coil magnetic absorption to control the pressure of the spring drive pneumatic valve core movement, is an electromagnetic coil, simple structure, cheap price, can only complete the switch; Electric pneumatic valve is a motor driven by pneumatic valve stem, drive the pneumatic valve core movement, the electric pneumatic valve and points ( Close to snuff out pneumatic valve and control valve. Dynamic valve is closed to snuff out the two type of work that is fully open and close, regulating pneumatic valve is a device on the electric pneumatic valve positioner, a closed loop control to the pneumatic valves on the dynamic stability in one place.


the use of electric pneumatic valve and solenoid pneumatic valve:


pneumatic valve, electromagnetic switch control for liquid and gas pipe line, is the control of the two DO. Common control for small pipes.


electric pneumatic valve, pipeline system used for liquid, gas, the breeze recuperated medium flow amount of imitation, is AI control. In large pneumatic valve in the control of the breeze system will also be able to do two switch control with electric pneumatic valve.


: pneumatic valve can only be used as a switch, and is the DO control, can only be used for small pipe control, common in DN and the following pipe, up a little.
electropneumatic valve: can have AI response signal, and can be controlled by the DO or AO, analogy can be found in large pipe breeze pneumatic valve, etc.


, switch mode:


solenoid pneumatic valve through the coil driver, only on or off, switch action when time is short. Common is to use motor electric pneumatic valve, open or close finish demand must imitate the amount of time, can do control.


, nature of work:


ordinary pneumatic valve flow coefficient is very small, and the work pressure difference is very small. For example the solenoid pneumatic valve flow coefficient of average diameter than the diameter of the electric pneumatic valve ball. Is driven by electromagnetic coil of electromagnetic pneumatic valve, compare easy to voltage shock damage. Equivalent to the role of the switch is on or off a role. Electric pneumatic valve is common with motor, voltage impact resistance. Electromagnetic air valve is closed fast and fast, normally used in the small flow rate and pressure, the request switch frequency big central electric pneumatic valve and vice. Electric pneumatic valve pneumatic valve can control the openings of the state is open, closed, half-open half closed, can control the medium inside the pipeline flow and solenoid pneumatic valve can not reach the request. Common power can reset electromagnetic pneumatic valve, electric pneumatic valve should be installed to the function of such demand and reset.


, suitable process:


some special to process the request, solenoid pneumatic valve suitable for leakage, fluid medium, such as special, the price is more expensive. Common used to regulate electric pneumatic valve, also has the switch quantity, for example: baking-free brick machine electromagnetic pneumatic valve.
