The Fontaine SERIES 25 Channel Gate is the same construction as the SERIES 20 Sluice Gate except that it does not have a top seal. It is made of stainless steel and has very high corrosion and erosion resistance, allowing many years of operation with minimum maintenance. The gate is also lighter and easier to handle and install than those made of cast iron.

The unique sealing system of the SERIES 25, with its UHMWPE side seals that extend up to the top frame, keep leakage in positive seating below 0.05 U.S. gpm per foot of perimeter (0.60 l/min per metre), which is just half the maximum allowed by AWWA standard C513.
SERIES 25 is available with various mounting options and can be installed in any channel.
The Fontaine SERIES 25 gate is designed to control water flows in channels. It is the same construction as the SERIES 20 with the exception that it is not equipped with a top seal. The maximum allowable leakage is 0.05 U.S. gpm per foot (0.60 l/min per meter) of perimeter in seating and unseating head conditions (head conditions taken is equal to the height of the slide). It is available in sizes up to 120”(3048 mm).
Stainless Steel Construction
Because of its stainless steel construction, the SERIES 25 has a very good corrosion and erosion resistance and can be operated many years with a minimum maintenance. The stainless steel construction allows a very large design flexibility, the result beeing a lighter weight and easier-to-install channel gate.
The SERIES 25 gates are designed to meet and exceed all AWWA C513 standards with the exception of the material. The result is a highquality gate with a very long life expectancy. As specified in the AWWA standard, most Fontaine SERIES 25 water gates are tested for operation before shipping .
Stainless Steel Frame
The stainless steel frame on the SERIES 25 is offered in flange back type for installation on a concrete wall at the end of a channel. It is also available for installation in an existing channel or embedded into the walls of a new channel. The frame can be either open (no yoke) or selfcontained configurations, providing a solid onepiece gate. The open frame is usually used for the manual gates (no operator). In the case of an open frame with operator, an operating floor located over the channel to support the pedestal is necessary. The inferior section is available in flush-bottom frame (embedded or wall mounted) or conventional seating (existing channel).
The slide consists of a stainless steel plate reinforced with horizontal members welded to the plate, making it a solid single piece.
The unique side seals of the SERIES 25 are the same as on the SERIES 20 and allow no metalto- metal contact. They are made of a selflubricating ultra high molecular weight polyethylene (UHMWPE). With a friction coefficient of 0.2, the seals make the gate easy to open even when not operated for a long period. The self-adjusting quality is obtained by a compression cord that guarantees a perfect watertight seal between the slide and the frame in both seating and unseating conditions. The seals extend all the way to the top of the frame making the SERIES 25 a water control gate in addition to having the characteristics of a channel gate. The SERIES 25 is designed for many applications. Details 25-01, 02, 03 show the three most common mountings.
