Aluminum Stop Gates

Introduction

Series 500 Stop Gates

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.

Aluminum Stop Logs

Series 500 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.

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.
