 Symbol:
2-way valve 3-way valve
 Appearance:
2-way valve 3-way valve
 Function:
2-way valve: to build up or cut off a passage. When power off, the passage from the inlet of the valve
to outlet is cut off; when power on, the passage is built up.
3-way valve: to switch among passages. When power off, the public end (COM) and the NO (normally
open) end are connected; when power on, the public end and the NC (normally closed)
end are connected.
Note: the operating voltage of valves is 12V, and maximal bearable pressure is 200KPa. The internal
movement of the valves is driven by electromagnet and the restoration is driven by the spring,
so it is recommended not put the valves power-on for too long. When the electromagnet valve
is working, the spring pole will lower down, and it will rise to the initial position when power
off. You can touch the valve body and feel to determine whether it is in action.
