摘要：
A backwater valve has a valve body, and a valve member pivotally movable about a pivot axis between an open position away from the valve body and a closed position covering the valve body. A control linkage is provided with at least one of a float or a counterweight in communication with the valve member via the control linkage to modify operation of the valve member.
