On-Seating or Off-Seating:

When pressure pushes the gate towards the sealing surface, it is called On-Seating. When pressure pushes gate away from the sealing surface, it is called Off-Seating.


Penstocks can be assembled on wall surface or to side walls inside a channel. They can also be embedded in the concrete.

Weir Gates:

Ordinary Penstocks are opened upwards, while if a Penstock is opened downwards to achieve a controlled overflow, we call them Weir Gates.
