What are the differences between these three sets of solenoid valves? :With the handshake mechanism, it’s difficult to distinguish the symbols on both sides, and the principle behind the operation of the valve core is not clear. One more question: whether it’s a dual-control or single-control system, once the solenoid is activated electrically, does its coil remain powered continuously?
Break it down completely by yourself, take a look, and think about it； After seeing enough and thinking enough, one will understand.
Symbols on both sides: the box on the left indicates the direction of fluid flow and the ports when power is applied, while the box on the right indicates the direction of fluid flow and the ports when no power is applied. It should be noted that the arrow inside the box indicates that the fluid is in a connected state, but the direction of the arrow does not necessarily represent the actual direction of the fluid flow.
