Detailed Introduction:

Flap valve which depends on its gravity and pressure difference inside and outside and shoot the door, open and close 

automatically to achieve the effect of overflow and non-return valve devices, including tidal gate valve, check valve or one-way valve.

preventing backflow. Used in reservoirs, tidal basins, ponding basins, pump stands and storm drain systems where seating 

heads are less than ten feet.
