AquaNox - The water is no longer calm. The undersea world has undergone a transformation from tranquil environment to a place of unspeakable violence, graphic murder and horrific danger. It is now the 27th century and mercenaries such as 'Emerald' Dead Eye Flint ply their deadly trade among the warring forces of man and nature. Gamers take the role of Flint, taking command of a loosely aligned.

Series 40 - Weir Gate For Flow and Level ControlCan be supplied in a multitude of shapes The self-adjusting sealing system allows precise flow measurement Low-maintenanceThe Fontaine-Aquanox SERIES 40 weir gate is used to control flows and level in different applications by opening downwards and allowing water flow over the stainless steel plate. The SERIES 40sealing system design is similar to that of the SERIES 20.Because of its stainless steel construction, the SERIES 40 has high corrosion and erosion resistance, and can be operated many years with minimum maintenance. 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.SERIES 40 gates are built to meet or exceed AWWA C561-14 standards pertaining to the design safety factors, stem and stem couplings, stem guides positioning, manual lifting devices, and leakage.The stainless steel frame on the SERIES 40 is a flange back type (Fig. 40-02) 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 be installed on many applications.The slide consists of a stainless steel plate reinforced with horizontal members welded to the plate, making it a solid one-piece slide.
It can be fabricated in various shapes to control and calculate the flow of water.The side and bottom seals (fig.40-02, 03) are the same as on the SERIES 20, allowing no metal-to-metal contact. They are made of a self lubricating ultra-high molecular weight polyethylene (UHMWPE). With a friction coefficient of less than 0.2, the seals make the gate easier to operate even after a long period of inactivity.
The self-adjusting quality is obtained by a continuous compression cord which guarantees watertight seal between the slide and the frame in both seating and unseating conditions. The bottom seal (fig.
