Different Valve Types
There are three different valve types, which are:
•
The valve is driven by an electric motor that is able to rotate in both directions. Two wires are connected to this type of valve from the controller. To rotate the motor 12V is applied to one of the wires whilst GND is applied to the other. When opposite voltage is applied to the two wires the motor will rotate in the opposite direction.
Common terms for this system are Reverse Polarity or
•
The valve is driven by an electric motor that is able to rotate in both directions. Unlike the
Contsant 12V and GND are required in addition to the signal wire.
•Solenoid
Solenoid Valves usually consist of a coil, that when exposed to voltage produces a magnetic field. The magnetic field draws a needle against a spring away from its seat, to allow liquid to flow.
