Two five-way solenoid valve working principle and common faults

                              Two five-way solenoid valve working principle and common faults

Five is that there are five tunnel ventilation, including 1 P and air connections, two A/B and external double-acting cylinder chamber in and out of the port connection (connected to the pneumatic valve and so on), two (R, S) and the in and out of the port of the internal chamber (exhaust), illustrated by the two five-way solenoid valve for double electric control (i.e., double coil), AB out connected with A pneumatic valve cylinder, cylinder when the upper airway is open valve, cylinder bottom is close the valve.

Commonly used coil voltage grade DC24V, AC220V, etc. Near by the coil in A charged, gas path - P - A it had, it galls A out of the line; The same magnetic coil near B charged, PB also. R and S are two vent, see the copper is on the drawing silencer.

Control design we do is to control the electromagnetic coil to electric power, it's important to note that limit of gas path and valve interlocking relationship can't make a mistake, is the control of a pneumatic valve solenoid coil must be locked in place and the limit of interlocking, open control valve and the electromagnetic coil of gas path must be in place of the open limit interlock; Site is likely to be the wrong line or wrong gas path, before sending check A/B export gas path can judge whether it is right.

If only a single control coil, it can complete the function of the electric valve open or close the valve (see the electric coil)
