GENERAL DESCRIPTION
The ORBINOX model MU is a flush bottom 4 sided sealing slide
gate. The gates are suitable for different types of applications
with a highly versatile flow control for waste water treatment
plants, irrigation, hydraulic works and hydro-electric power
plants.
From sizes 6” x 6” (150mm x 150mm) to 48” x 48” (1200mm
x 1200mm), the MU model has a unique self adjusting seal
design that can achieve minimal equal seating and unseating
(bidirectional) leakage rates. Sizes 52” x 52” (1300mm x
1300mm) up to 160” x 160” (4000mm x 4000mm) are
available in both uni-directional (only suitable for seating water
heads) and bi-directional configurations.
The leakage rate is 50% or better of the maximum allowable
recommended by AWWA (C561) under normal conditions.
ORBINOX also designs and manufactures the MU Slide Gate in
larger sizes, for more demanding service conditions and
maintains a leakage rate below the allowable standard from
AWWA. For more information please contact an ORBINOX
representative.
DESIGN STANDARD
The MU Slide Gate is manufactured in general accordance with
AWWA C561
The standard MU model is manufactured in stainless steel which
has a higher corrosion resistance in many applications which
results into a longer life cycle with little or no maintenance. Other
materials of construction are available upon request, such as AISI
904L, Duplex stainless, etc.

STEM EXTENSIONS
In most cases, the operating floor level is located substantially
higher than the opening. In order to be able to operate the gate,
stem extensions are necessary. Stem guides are used to limit the
“unsupported” length of the stem extension in order to avoid any
buckling failure. The stem guide has a HWMPE guide to reduce
friction between the guide and the extension
NON-RISING STEM CONFIGURATION.
As standard, non-rising stem gate configurations are used with self-
contained frame designs. Therefore, the stem extension does not
support the axial load (only torque) and less wall brackets are
required. As a general rule, a stem guide should be installed every
10 feet (3 meters) of unsupported stem extension.
RISING STEM CONFIGURATION
As standard, rising stem gate configurations are used with open-
frame designs. Therefore, the stem extension has to support the
axial load when the gate is operated. In consequence, the use of
stem guides is critical to avoid any buckling failure. As a general
rule, a stem guide should be installed every 6½ feet (2 meters) of
unsupported stem extension.

This section briefly describes the installation, operation
and maintenance of MU Slide Gates. For more detailed
information please refer to the “MU IOM Manual”
INSTALLATION:
ORBINOX MU Slide Gates are installed by means of
anchor bolts. Depending on the size and working
conditions they shall be either of the mechanical or
chemical type (see table below). In order to avoid
leakage between the concrete wall and the frame,
ORBINOX recommends the use of construction sealant
equivalent to Sikabond Construction Sealant (200ml
per meter of opening perimeter)
The minimum concrete strength shall be 3,000PSI (20.7
MPa). The concrete construction tolerance (flatness, levelness
and plumbness) shall be in accordance to ACI 117-10. For
detailed information about type, size and quantity of the
required anchor bolts for installation, please refer to the
notes on the “General Arrangement Drawing”
MAINTENANCE AND OPERATION:
The ORBINOX MU Slide Gates need practically no
maintenance. The stem should be kept lubricated and seals
should be replaced if damaged. The MU Slide Gate is
closed by applying a clockwise rotation. Applying excessive
force on the operator when closing the gate may cause
damage to the stem

recommendations of the equipment manufacturer unless
exceptions are noted by the engineer. Gates and operators
shall be supplied with all necessary parts and accessories
indicated on the drawings, specified or otherwise required
for a complete, properly operating installation, and shall
be the latest standard product of a manufacturer regularly
engaged in the production of fabricated gates. Gates
supplied under this section shall be Model MU Stainless
Steel Slide Gates as manufactured by ORBINOX.
GOVERNING STANDARDS. The sluice gates specified in
this section shall be manufactured in general accordance
to AWWA C561, latest edition.
QUALITY ASSURANCE. The manufacturer shall have
experience in the production of substantially similar
equipment, and shall show evidence of satisfactory
operation in at least 50 installations. The manufacturer's
shop welds, welding procedures and welders shall be
qualified and certified in accordance with the requirement
of the latest edition of ASME, Section IX. Gates shall be
shop inspected for proper operation before shipping.
SUBMITTALS. The manufacturer shall submit for approval
by the purchaser, drawings showing the main dimensions,
general construction and materials used in the gate.
Maximum allowable leakage
Gallons per minute per foot of perimeter:
= 0.10 + (0.0024 x (unseating head in feet - 20))
Liters per minute per meter of perimeter:
=1.24 + (0.101 x (unseating head in feet - 6.1))
Example: If we have a gate with 30 feet head, the leakage for the
unseating head will be:
0.10 + (0.0025 x (30 –20)) = 0.125 US gpm/ft of perimeter.
PERFORMANCE
LEAKAGE. Slide 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 (0.62 l/min per meter) of seating
perimeter. Under the design unseating head, the leakage
for heads of 20 feet (6m) shall not exceed 0.05 U.S. gallon
per minute per foot (0.62 l/min per meter) of seating
perimeter. For unseating heads greater than 20 feet (6m),
the allowable leakage shall be the rate per foot (meter) of
perimeter specified by the following equations or better:
DESIGN HEAD. The slide gates shall be designed to
withstand the design head shown in the schedule.
SEAL PERFORMANCE TEST. The gate’s seating system
should have been tested through a cycle test and should
show that the leakage requirements are still obtained with
a minimum deterioration.
PRODUCT (SLIDE GATE)
GENERAL DESIGN. Gates shall be either self-contained or
non self-contained and of the rising stem, or non-rising
stem configuration as indicated on the gate schedule.
WALL THIMBLE. The wall thimble (optional) shall be
stainless steel and supplied by the gate manufacturer. Refer
to the gate schedule for type and applicable locations.
Material thickness should be according to the
manufacturer's recommendations and be of sufficient
resistance to handle the operating forces.
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 suitable for mounting on a
concrete wall (wall mount). The frame configuration shall
be of type and design that shall allow the replacement of
the side and bottom seals without removing the gate frame
from the concrete wall or wall thimble. The minimum
thickness at the frame members shall be 1/4 " (6,35mm).
The design stress shall not exceed the lesser of 50% of the
yield strength or 25% of the ultimate strength of the
materials for maximum load conditions.

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 or 1/16", whichever is less,
under the design head. The minimum thickness shall be
1/4”. The design stress shall not exceed the lesser of 50%
of the yield strength or 25% of the ultimate strength for
maximum load conditions
GUIDES AND SEALS. The guides shall be made of
UHMWPE (ultra high molecular weight polyethylene).
Guides shall be self-cleaning, providing a relief gap for the
evacuation of foreign media. Side and top seal shall be
made of EPDM and shall be of the self adjusting lip design
(wedging devices are not acceptable). The bottom seal
shall be made of resilient EPDM set onto the bottom
member of the slide and shall be replaceable without
removing the gate frame from the wall or wall thimble.
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 the manufacturer's recommendation. The
slenderness ratio shall not be greater than 200
STEM COVER. Rising stem gates shall be provided with a
carbon steel or a clear polycarbonate stem cover. The
clear polycarbonate stem cover shall have a cap and
condensation vents and a clear position indicating tape.
The tape shall be field applied to the stem cover after the
sluice gate has been installed in place and positioned.
ACTUATORS. Manual operators of the types listed in the
schedule shall be provided by the gate manufacturer. All
bearings and gears shall be totally enclosed in a weather
tight housing. The pinion shaft of crank-operated
mechanisms shall be constructed of stainless steel and
supported by roller or needle bearings. Each manual
operator shall be designed to operate the gate under the
maximum specified seating and unseating heads by using
a maximum effort of 40 lbs (178 N) on the crank or hand
wheel, and shall be able to withstand, without damage, an
effort of 80 lbs (356 N). The crank shall be removable and
fitted with a rotating handle. The maximum crank radius
shall be 15 inches (381mm) and the maximum hand wheel
diameter shall be 30 inches (750mm) unless otherwise
specified. Electric motors shall meet AWWA 542-09
Standard and pneumatic and hydraulic actuators AWWA
541-08 Standard.
YOKE. Self-contained gates shall be provided with a yoke
made of structural members or formed plates. The
maximum deflection of the yoke shall be 1/360 of the
gate's span or 1/4", whichever is less. The design stress
shall not exceed the lesser of 50% of the yield strength or
25% of the ultimate strength of the materials for maximum
load conditions.
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
hand wheel. The stem shall have a slenderness ratio less
than 200. The threaded portion of the stem shall have
machined cut threads of the Acme type or metric DIN
103. Where a hydraulic, pneumatic or electric operator is
