Solenoid
Valves
1. The solenoid valve is a switch valve with an inlet and an outlet. Whichever coil is energized which outlet exhausts when the coil is de-energized it closes - stops exhausting. The voltage can be selected in various ways as can the trachea diameter. Its flow diameter is 2.4mm. After our improvement the valve can be used for both positive and negative pressure.
2. Our matching pipe fittings are equipped with sealing rings (4 6 8 10mm) and the G thread can be tightened by hand after receipt which is very convenient - no need to use other sealants.
3. Regarding the power connection: There are three terminals the left and right are positive and negative and the single protrusion is ground. If the left and right positive and negative poles are connected correctly the indicator light will be on. If it is wrong the indicator light will not be on but the valve can still work and switch normally.
