I understand a little better. So on SMC's website, when it says 5 ports, you mean there are two that are just relief ports (1 input, 1 output A, 1 output B, 2 relief ports)? In other words, is this a 1 port in, 2 port out?

So say I needed a solenoid valve with 1 in, 4 out, then this SYJ series is incompatible with what I am looking for?

I am just trying to understand the lingo. Also, is there a good tutorial I can read up on so I can understand those diagrams of the valves?

Sorry... I thought this forum was open to everyone.
