Plasti-Fab FRP Flow Control Products: DOW Gates

Downward-Opening Weir (DOW) Gate:  Standard & HDTS

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.
