Series 500 Stop Gates Aluminum Stop Gates Introduction The stop gates illustrated in this section are the types most commonly used. Rugged aluminum construction is combined with tough, flexible ultra high molecular weight polyethylene (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 DESCRIPTION Frames: Stop Gate frames are designed to be embedded (Model 501), mounted on the face of a wall (Model 503) and mounted in an existing channel (Model 503-C). The side guides are a rugged aluminum extrusion with an easily replaceable polymer seating/sliding liner. The sill is also an aluminum extrusion with an easily replaceable neoprene flush seating surface. Slides: The slide is constructed from flat aluminum plate, sufficiently reinforced for the design head 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 stop gates to 0.10 gallons per minute per foot of wetted perimeter when specified.

Technical Information: In addition to submittal information required by other sections of these specifications, the stop gate manufacturer may be required to submit design calculations and supporting data for all gates showing stresses, loads and deflection for critical parts under design head conditions. At a minimum, these shall include operating load, slide deflection, slide bending 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 the upstream and downstream sides of the slide.

Series 500 Stop Logs Aluminum Stop Logs Introduction Stop 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. The availability of wood in the sizes, quality and quantity to make traditional stop logs has become increasingly difficult. The lack of dimensional stability in wood also makes it very difficult to provide timber stop logs with predicatable leakage characteristics. As the following chart illustrates, Whipps series 509,510 and 511 Stop Logs are suitable for a large range of channel widths and water depths while providing a guaranteed maximum leakage rate of.05 gallons per minute per linear foot of wetted seal, This series of Aluminum Stop Log has been in continuous production since 1980 providing an affordable and effective water flow control alternative for many types of projects.

Series 500 Stop Logs Advantages The following pages show the standard range of stop log heights, channel widths and total water depths. Many other configurations can be designed to customize these stop logs to accomodate 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 also designed to seal correctly when adjacent logs arc laterally offset up to 1/2". All seals are stop log mounted for ease of inspection and repair and to eliminate the potential for damage from debris that is 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 which enables outstanding delivery of stop logs, including custom designs. Stop logs of this type have demonstrated 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 provides an 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 to provide an adequate seal when adjacent stop logs are laterally offset up to 1/2". All contact surfaces for the stop log seals have a smooth mill finish. Welds on the down stream side of the stop logs are continuous. Adequate drainage is provided for the interior of the stop logs to prevent bouyancy or retention of water. One Piece Molded Polyurethane Comer Seal View of Typical Bottom Corner (Model 510, 12" High Shown) Stop Log Grooves Aluminum Stop Log Grooves are one (1) piece aluminum (6061-T6) extrusions with integral concrete anchors for embedded applications. Face mounted and channel mounted applications as shown on pages 9,11 and 13 are also available. Stainless Steel Stop Log Grooves are a formed and welded with integral concrete anchors for embedded applications. Face mounted and channel mounted applications as shown on pages 9,11 and 13 are also available. Cast Iron Stop Log Grooves are cast with integral concrete anchors and machined on all stop log contact surfaces. This design is for embedded applications only. Scries 500, Page 7
