The detailed distinction between motorized valve and solenoid valves and the different USES?
First of all, from a large scale, solenoid valve also belong to electric accessories, are both need electricity, to open the valve, but electric valve is directly after the power supply leads to a lifting force, drive the valve stem, and electromagnetic valve is after electrify, coil to produce electromagnetic force, drive the electromagnetic valve core is open or closed, and then to the pneumatic cylinder expired, drive valve opening and closing, that is to say, the electromagnetic valve must have the compressed air supply, and cylinder, and not for an electric valve, directly to the valve.
Second, the lifting force of the electric valve will have more than the electromagnetic valve, corresponding to open the valve diameter is larger, the electric valve is not capable of high temperature, 150 degrees or more, using electric valve is easy to burn down the motor, and electric valve sealing performance than electromagnetic valve is bad, in ascension when the stem is also very easy to distortion, namely opened excessive or insufficient, open and these shortcomings solenoid valve can be normal operation, can be classified as strengths.
Finally, commonly used in electric valve, the requirements for sealing is not high, the temperature is not high also, and to open the accuracy is not high, the corresponding electromagnetic valve is basic to use on the accuracy of open, suggested that if the factory have gas source as far as possible the use of electromagnetic valve.
