2, pressing type self-locking mechanism, can prevent the setting pressure caused by external interference and change;

3, the pressure regulating mechanism adopts the balanced design, the pressure regulating is more stable, the drift is small, the pressure characteristic is good;

4. In addition to panel installation, fixed bracket installation can be selected;

5, in addition to the standard form, another low pressure type is available for choice (high adjustable pressure 0.4MPa).
