Downward Opening Weir Gate

The function of a down-opening weir gate is to control the upstream water level, and/or pace the amount of discharge from a water system. At times there will be a level control sensor in the system which is directly connected – controlling a modulating electric operator to automatically pace the amount of flow discharged and/or maintain a constant upstream water depth.

Downward opening Weir Gate Construction Specifications

Depending on the size of the weir opening and the heads involved, the downward opening weir gate can be constructed as a sandwich style penstock, a one-inch solid FRP gate, or as a Heavy Duty Titeseal gate. If possible, weir gates should be installed to operate with a seating head to obtain the best leakage performance. However, they can also be designed for unseating heads as well.
