The below guide shows a SLGPC PU220AR valve. The process is exactly the same for the Shako and other similar valves.
Then flip the coil around and remove the screw that holds the coil to the terminal block. Separate the 2 parts. Here the cover from the terminal block has separated. Sometimes the whole part will pull away from the coil. Either way is fine.
If you have a terminal block without markings just follow the above. With DC valves it doesn’t really matter, either way will work. With coils that have an LED vcc normally goes to the screw terminal that is connected to the LED.
If you tied a knot you may need to wiggle the wire to get the cover fully back on.
Note that I have rotated the contacts cover by 180 degrees so that when the valve is re-assembled the opening for the lead is away from the nozzle.
Attaching the Nozzles
The nozzles simply screw in to the block, however, without Teflon tape they will leak.
It is personal preference to whether or not you have the tape showing.
