Fontaine Slide Gates – Series 20

Fontaine’s innovative design revolutionized the gate industry in the 1980’s. The high quality, service life and ease of use compared with cast iron gates made Fontaine a market leader in the industry. After a period of being merged with Rodney Hunt under Rexnord Fontaine is back with the original group of professionals and supplying high quality gates that define quality in the industry.

Fontaine-Aquanox’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 the required seating and unseating heads. The seal design keeps the allowable leakage rate to 0.04 U.S. gpm per foot (0.50 l/min per meter) of seating perimeter.

Because of its stainless steel construction, the SERIES 20 has high corrosion and erosion resistance, and can be operated for many years with minimum maintenance. Stainless steel provides virtually limitless design flexibility. The result is a lighter weight and easier-to-install gate.

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-Aquanox SERIES 20 water gates are tested for leakage and operation before shipping.

Features:

Flange Back Frame

The stainless steel frame on the SERIES 20 is a flange back type ( fig.20-02) 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 Frame

The slide is a stainless steel plate reinforced with members welded to the plate, making it a solid single piece.

The side and top seals (fig. 20-03, 04) 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. The flush-bottom seal (fig. 20-05), leaves the opening unobstructed when the slide is in the open position.

Mounting Options:

The SERIES 20 has many different mounting options available.
