4 and 5 ways
This solenoid valve is the functional combination of two 3 way valves. It includes generally 4 or 5 connection ports according to its design. The term 4 way or 5 way refers to the number of ports.

a.
1 port inlet fluid
P
2 ports are the outlet
A1, A2
1 or 2 ports are the exhaust
R1, R2
