Weir Gates

Weir gates are downward opening overflow gates and distinct from downward opening sluice gates. These are provided with sealing arrangement on 3 sides and the sealing arrangement ensures continuous sealing on 3 sides ( 2 sides and bottom ) at any extent / position of gate opening allowing water to overflow only from top side. These are used either for (i) decanting of a reservoir or a tank, or  (ii) maintain precise level control in a reservoir or a tank, or (iii)  to isolate the flow as well as maintain precise level control by providing optional 4th side (top side ) sealing arrangement.

These are offered in varied designs and various materials of construction such as Cast Iron / Ductile cast iron / Alloy cast iron with Nickle / Stainless steel / Super Duplex stainless steel / Aluminum / Composite etc to suit the intended application. These can be provided with manual, electric , pneumatic or hydraulic operating systems.
