inc.Series 500 Stop GatesAluminum Stop GatesIntroductionThe stop gates illustrated in this section are the types most commonly used. Ruggedaluminum construction is combined with tough, flexible ultra high molecular weightpolyethylene (UHMW) scats/seals. This design achieves a very low level of leakage.Stop gates can also be supplied in a similar rugged stainless steel design.PRODUCT DESCRIPTIONFrames:Stop Gate frames are designed to be embedded (Model 501), mounted on the face of awall (Model 503) and mounted in an existing channel (Model 503-C). The side guidesare a rugged aluminum extrusion with an easily replaceable polymer seating/slidingliner. The sill is also an aluminum extrusion with an easily replaceable neoprene flushseating surface.Slides:The slide is constructed from flat aluminum plate, sufficiently reinforced for the designhead conditions. An appropriate lifting handle is attached near the top of the slide.Leakage:The superior design of the polymer seating surfaces has reduced leakage for these stopgates to 0.10 gallons per minute per foot of wetted perimeter when specified.Model 501OPENING6"(150 mm)wtrAfc.TYPICAL BOX-OUT—*GUIDE SECTION A-A INVERTIvP a4oVW 41J(100mm}typical box-out-INVERT SECTION B-BSeries 500, Page 3

illC.Series 500 Stop GatesAluminum Stop GatesGeneralQuality Assurance: The stop gate shall be the product of a manufacturer having 10 years ormore experience in the successful design and manufacture of low leakage stop gates undersimilar design conditions. All welds shall be performed by welders with AWS certification.Performance: Maximum allowable leakage for the stop gates shall be 0.10 gallons perminute per linear foot of wetted perimeter regardless of the direction of the unbalanced head.Acceptable manufacturers: Whipps Inc., Athol, Massachusetts, Series 501,503,503-C orEngineer approved equal.Technical Information: In addition to submittal information required by other sections ofthese specifications, the stop gate manufacturer may be required to submit design calculationsand supporting data for all gates showing stresses, loads and deflection for critical parts underdesign head conditions. At a minimum, these shall include operating load, slide deflection, slidebending stress and shear stress in stiffener welds.Frame: The frame shall consist of 1/4" minimum thickness extruded aluminum (Alloy 6061 T6) incorporating ultra high molecular weight polymer (UHMW) seat/seal facings on both theupstream and downstream sides of the slide. Each seat/seal will be shaped to provide twobearing surfaces and two sealing edges. The gate side guides and invert shall have a minimumweight of 4 lbs./ft. for wall mounted and 3 lbs./ft. for embedded. The gate invert shall containa removable neoprene seal. Seals attached to the slide will not be acceptable. All necessaiyassembly and anchor bolts shall be type 304 (type 316 optional) stainless steel and shall beprovided by the gate manufacturer.Slide: The slide shall be minimum thickness of 1/4" aluminum plate (Alloy 6061-T6)reinforced with stiffeners as required so that at the design head the slide will not deflect morethan 1/360 of its width and stress is limited to 7600 psi. Slide stiffeners shall have a minimumweight of 2.5 lbs./ft. The slide shall be provided with a cast aluminum offset lifting handle. Duallifting handles shall be provided on gates wider than 36".Painting: All aluminum in contact with concrete shall have a heavy shop coat ofbitumastic paint.(ANODIZING optional): All aluminum components shall be anodized in conformance withAluminum Association Specification AA-C22-A41. The anodizing shall be 0.7 mil thick witha nickel acetate sealer.Series 500, Page 5

inc.Series 500 Stop LogsAluminum Stop LogsIntroductionStop Logs have been used for many years to contain water in ponds, tanks, or channels.They are used in applications where their installation or removal is required infrequently.Historically, stop logs have been made from squared timbers as their name suggests. Theavailability of wood in the sizes, quality and quantity to make traditional stop logs has becomeincreasingly difficult. The lack of dimensional stability in wood also makes it very difficult toprovide timber stop logs with predicatable leakage characteristics.As the following chart illustrates, Whipps series 509,510 and 511 Stop Logs are suitable fora large range of channel widths and water depths while providing a guaranteed maximumleakage rate of .05 gallons per minute per linear foot of wetted seal, This series of AluminumStop Log has been in continuous production since 1980 providing an affordable and effectivewater flow control alternative for many types of projects.Stop Log Application Chart(@ 7600 P.S.I.

inc.Series 500 Stop LogsAdvantagesThe following pages show the standard range of stop log heights, channel widths and totalwater depths. Many other configurations can be designed to customize these stop logs toaccomodate other stop log heights, channel widths or total water depths.All seals are designed to provide 1/8" compliance with the groove sealing surface and alsodesigned to seal correctly when adjacent logs arc laterally offset up to 1/2". All seals are stop logmounted for ease of inspection and repair and to eliminate the potential for damage from debris thatis always possible when the side seals are mounted in the sides of the stop log grooves.The Whipps Series of Proprietary Stop Log shapes are normally carried in stock whichenables outstanding delivery of stop logs, including custom designs. Stop logs of this type havedemonstrated excellent service life in both water and waste treatment plant applications.Design Features" Stop Logs are aluminum (6061-T6), 5/16" minimum thickness and maximum 7600 psi stress. The specially shaped urethanc seal attached to the bottom and ends of the stop logs providesan uninterrupted seal at the face of the stop log groove and the joint between the stop logs.The bottom stop log seals with the flush invert of the channel. The urethane seal is sufficiently compliant to deflect 1/8"under normal conditions of installation and wide enough toprovide an adequate seal when adjacent stop logs arelaterally offset up to 1/2". All contact surfaces for the stop log seals have asmooth mill finish.Welds on the down stream side of the stop logsOne PieceMolded PolyurethaneComer Sealare continuous.Adequate drainage is provided for the interior of theView of Typical Bottom Cornerstop logs to prevent bouyancy or retention of water.(Model 510, 12" High Shown)Stop Log GroovesAluminum Stop Log Grooves are one (1) piece aluminum (6061-T6) extrusions withintegral concrete anchors for embedded applications. Face mounted and channel mountedapplications as shown on pages 9,11 and 13 are also available.Stainless Steel Stop Log Grooves are a formed and welded with integral concrete anchorsfor embedded applications. Face mounted and channel mounted applications as shown onpages 9,11 and 13 are also available.Cast Iron Stop Log Grooves are cast with integral concrete anchors and machined on allstop log contact surfaces. This design is for embedded applications only.Scries 500, Page 7
