STRUT VALVE OPENED & CLOSED WITH 3/4" WRENCH.
The STRUT valve enables you to SAFELY STOP nitrogen pressure entering a damper.

On the other hand these 3 valves all have pin cores in them.

Not only are the pin type valves dangerous, but also you have to spend 500 on a regulator and 250 on a pre-fill tool, to use them.
