　 The gate adopts NO design, hence water supply will not be affected due to instability in inlet pressure.

The internal pressure control chamber adopts diaphragm design, hence the function and life-time will not be affected by water impurity. Besides, there isl no leakage by this design.

When the outlet pressure directly responds to pressure control chamber to adjust setting pressure the response is sensitive and adjustment can be very precise.
