The Fontaine-Aquanox series 40 weir gate is used to control flows and levels in different applications, both in wastewater and potable water. The series 40 weir gates open downwards therefore allowing water to flow over the stainless steel slide plate. This gate configuration is ideal for either flow control (for decanting) or level control applications. The series 40 sealing system design is similar to that of the series 20.
Usage:
-
Wastewater
-
Potable Water
-
Due to its stainless steel construction, the series 40 has high corrosion and erosion resistance, and can be operated many years with minimum maintenance. Fabricated stainless steel allows the weir to be fabricated in a multitude of shapes to measure flows. The most common shapes used for measuring flows are the rectangular weir or the 90 degree V-notch weir.
-
The stainless steel frame on the SERIES 40 is a flange back type available in open or self-contained configurations, providing a solid one-piece gate.
-
The rigidity provided by the frame makes it easier to handle in transportation and installation, with less risk of distortion. The flange can be modified in order for the gate to beinstalled on many applications.
