Draft tube gates
- width up to 6 m, height up to 4 m, pressure up to 130 m water column
Fishbelly flaps
- for heights 1-6 m and span up to 40 m
Tainter gates
- for higher heads - for heights up to 15 m and widths up to 20 m
Stop – log gates
- for temporary locking of turbine inlets and outlets, sluices, and weirs
Vertical lift gates and emergency gates with wheels
-
emergency gates in front of the turbine
- design is similar to stop-log gates - they are able to close to full or partial discharge and they are mostly equipped with wheels
