[Pressure adjustment without tools]
Pressure adjustments can be made with one hand and locking performed with one push. Manual knob operation is easy when setting pressure as well.

[Easily handles panel mounting as well]
When the panel mounting nut is loosened, the nut acts as a jack and enables the knob to be removed easily. Fix the nut to mount in the panel. The L type bracket is also installed similarly to the nut.
