Four-way solenoid valve works
Four-way solenoid valve in our production of many applications, its working principle is as follows: When a current through the coil, the excitation effect, the fixed core pull the moving core, the moving core drive spool and compress the spring, changed Slide spool position, thus changing the direction of the fluid. When the coil is out of power, relying on the elastic force of the spring to push the spool valve, the top of the iron core, so that the fluid flow in the original direction. In our oxygen production, the molecular sieve switching system to force the valve switch is controlled by a two-position four-way solenoid valve, the air flow were supplied to both ends of the forced valve piston. In order to control the opening and closing force valve.
