Fontaine’s SERIES 20 Sluice Gate is a highly versatile flow control gate with various types of mountings. Adaptable to different applications, the Series 20 can be designed to withstand seating and unseating heads of up to 60 feet (18 m). When required, the SERIES 20 can be designed for higher water heads. The seal design keeps the allowable leakage rate to 0.05 U.S. gpm per foot (0.60 l/min per meter) of seating perimeter for seating head conditions. The unseating head leakage is 0.1 U.S. gpm(1.25 l/min per meter) per foot of perimeter up to 20 feet (6 m). Over 20 feet (6m)of unseating head, the leakage is corrected at a rate of 0.0025 U.S. gpm (0.03 l/min per meter) per foot of perimeter for each additional foot (meter) over 20 feet (6 m). The leakage rate is 50 % of the maximum allowable leakage recommended by AWWA. It is available in sizes from 6" (152 mm) up to 120" (3048 mm). For larger sizes, please contact a Fontaine representative. The design is suitable for square, rectangular or round applications.
Stainless Steel Construction
Because of its stainless steel construction, the SERIES 20 has high corrosion and erosion resistance, and can be operated for many years with a minimum maintenance. Stainless steel provides virtually limitless design flexibility. The result is a lighter weight and easier-to-install gate.
AWWA Standards
SERIES 20 Sluice Gates are built to meet or exceed AWWA C561 latest revision standards pertaining to design safety factors, stem and stem guides positioning, manual lifting devices, leakage, etc. As specified in the AWWA standard, all Fontaine SERIES 20 water gates are tested for leakage and operation before shipping.

Flange Back Frame
The stainless steel frame on the SERIES 20 is a flange back type (Detail 20-01) available in open or self-contained configurations, providing a solid one-piece gate. The rigidity provided by the flange back frame makes it easier to handle in transportation and installation with less risk of distortion. The seal bolting is completely separated from the flange anchoring, allowing the flange to be modified to better suit all particular applications. This feature also allows the gate to be completely factory assembled as well as tested for operation and leakage before being shipped. It also eliminates any on-site assembly and adjustments.
Reinforced Slide
The slide is a stainless steel plate reinforced with members welded to the plate, making it a solid single piece.

UHMWPE Seals (U.S. and Canadian Patents)
The side and top seals (Detail 20-02, 03) of the SERIES 20 are made of a self-lubricating ultra high molecular weight polyethylene (UHMWPE),allowing no metal-to-metal contact. With a friction coefficient of 0.2, the seals make the gate easier to open even when not operated for a long period of time. The self-adjusting feature is obtained by a continuous compression cord that ensures a tight seal between the slide and the frame in both seating and unseating conditions. The continuous wedging action of the compression cord on the slide enables the SERIES 20 Sluice Gate to control flow by allowing water only through the open portion of the gate.

To evaluate and measure the life expectancy and performance of the Series 20 UHMWPE self-adjusting seals, a series of tests have been conducted on a 24" x 24"(610 mm x 610 mm) sluice gate. To simulate the worst conditions, the gate was installed at the exhaust of a sandblast fan. The maximum wear on the seal after 25, 000 cycles was 0.05 inches. The leakage after the equivalent of 68 years with one cycle per day was 0.05 U.S. gpm per foot (0.60 l/min per meter) of perimeter at an unseating head of 30 feet.The leakage rate was still less than half the allowable leakage rate per the AWWA C561 standard.

Leakage
The following are the results of tests on several 24" x 24" (610 mm x 610 mm) Series 20 gates tested to meet the AWWA C561 leakage (0.2 U.S. gpm/ft. of perimeter) standard. The average leakage rate in unseating conditions is located at 0.028 U.S. gpm/ft per foot of perimeter. The gates can be adjusted, depending on their use, to a leakage as low as 0.01 U.S. gpm/ft. of perimeter.Each Series 20 gate is tested, and then a leakage test report is written. This report can be provided on request.

2. PERFORMANCE2.1. LEAKAGE. Sluice gates shall be substantially watertight under the design head conditions. Under the design seating head, the leakage shall not exceed 0.05 U.S. gallon per minute per foot (0.60 l/min per meter) of seating perimeter. Under the design unseating head, the leakage for heads of 20 feet (6m) or less shall not exceed 0.1 U.S. gallon per minute per foot (1.25 l/min per meter) of perimeter. For unseating heads greater than 20 feet (6m), the allowable leakage shall not exceed the rate per foot (meter) of perimeter specified by the following equations :
Maximum allowable leakageGallons per minute per foot of perimeter := 0.10 + (0.0025 x (unseating head in feet - 20))
Liters per minute per meter of perimeter := 1.25 + (0.1025 x (unseating head in meters - 6.1))
Example : If we have a gate with 35 feet head, the leakage for the unseating head will be :0.10+(0.0025 x (35 -20)) = 0.1375 US gpm/ft of perimeter
2.2. DESIGN HEAD. The Sluice gates shall be designed to withstand the design head shown in the schedule.

3.1.3. FRAME. The gate frame shall be constructed of structural members or formed plate welded to form a rigid one-piece frame. The frame shall be of the flange back design suitable for mounting on a concrete wall (CW), concrete wall with extra-wide flange (CWX), round manhole (RM), round manhole with extra-wide flange (RMX), a wall thimble (WT), or a standard flange (SF). The guide slot shall be made of UHMWPE (ultra high molecular weight polyethylene).
The frame configuration shall be of the flush-bottom type and shall allow the replacement of the top and side seals without removing the gate frame from the concrete or wall thimble.
3.1.4. SLIDE. The slide shall consist of a flat plate reinforced with formed plates or structural members to limit its deflection to 1/720 of the gate's span under the design head.
3.1.5. GUIDES AND SEALS. The guides shall be made of UHMWPE (ultra high molecular weight polyethylene) and shall be of such length as to retain and support at least two thirds (2/3) of the vertical height of the slide in the fully open position.
Side and top seals shall be made of UHMWPE (ultra high molecular weight polyethylene) of the self adjusting type. A continuous compression cord shall ensure contact between the UHMWPE guide and the gate in all positions. The sealing system shall maintain efficient sealing in any position of the slide and allow the water to flow only in the opened part of the gate.
The bottom seal shall be made of resilient neoprene set into the bottom member of the frame and shall form a flush-bottom.
3.2. OPERATORS AND STEM
3.2.1. STEM AND COUPLINGS. The operating stem shall be of stainless steel designed to transmit in compression at least 2 times the rated output of the operating manual mechanism with a 40 lbs (178 N) effort on the crank or handwheel.
The stem shall have a slenderness ratio (L/r) less than 200. The threaded portion of the stem shall have machined cut threads of the Acme type.
Where a hydraulic, pneumatic or electric operator is used, the stem design force shall not be less than 1.25 times the output thrust of the hydraulic or pneumatic cylinder with a pressure equal to the maximum working pressure of the supply, or 1.25 times the output thrust of the electric motor in the stalled condition.
3.2.1.1. For stems in more than one piece and with a diameter of 1¾ inches (45 mm) and larger, the different sections shall be joined together by solid bronze couplings. Stems with a diameter smaller than 1¾ inches (45 mm) shall be pinned to an extension tube.
The couplings shall be grooved and keyed and shall be of greater strength than the stem.
3.2.1.2. Gates having a width greater than two times their height shall be provided with two lifting mechanisms connected by a tandem shaft.
3.2.2. STEM GUIDES. Stem guides shall be fabricated from type 304L (or 316L) stainless steel. The guide shall be equipped with an UHMWPE bushing. Guides shall be adjustable and spaced in accordance with the manufacturer's recommendation. The L/r ratio shall not be greater than 200.
3.2.3. STEM COVER. Rising stem gates shall be provided with a clear polycarbonate stem cover. The stem cover shall have a cap and condensation vents and a clear mylar position indicating tape. The tape shall be field applied to the stem cover after the gate has been installed and positioned.
3.2.4. LIFTING MECHANISM. Manual operators of the types listed in the schedule shall be provided by the gate manufacturer.
