B Product feature
1. Embedded square pressure gauge is used to save
installation space. (External circular pressure gauge
is also optional).
2. The pressed-in self-locking mechanism can prevent
the abnormal movement of the set pressure caused
by external interfere.
3. Balanced design is adopted for the pressure
adjustment mechanism.
4. In addition to panel installation, the bracket is
optional for installation.
5. In addition to standard type, lower pressure type is
optional (the highest adjustable pressure is 0.4MPa).
