MODEL RB Weir Gates

OBXC 09-2010
GENERAL DESCRIPTION
The Orbinox model RB Weir Gate is designed for downward
opening applications where a more accurate flow control is re-
quired. The water flows over the top of the slide permitting a con-
stant upstream water elevation. The RB model weir gate is avail-
able from sizes 6”x6” (150mm x 150mm) up to
80”x80” (1200mm x 1200mm).
The sealing system is incorporated on 3 sides (both laterals and
bottom), resulting in a substantially watertight seal without the
need of wedges on the gate. This unique design achieves bidirec-
tional performance (seating and unseating pressure conditions).
Additionally, a 4 side sealing system is available.
The leakage rate on the model RB is lower than the maximum
allowable recommended by AWWA (C513-05) under normal
conditions. Orbinox also designs and manufactures the RB Weir
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 repre-
sentative.
DESIGN CONSTRUCTION
The RB Weir Gates (3 side sealing) is manufactured in general accordance to:
• AWWA C513-05 • DIN 19569 • BS 7775
For the four side sealing system, the gate is manufactured in general accordance to AWWA C561-
04.
The standard RB model is manufactured in stainless steel which has a higher corrosion resistance in
many applications which results in a longer life cycle with little or no maintenance. Other materials
of construction are available upon request, such as AISI 904L, Duplex Stainless, etc.

DESIGN FEATURES
Seating and Unseating Design Head:
The RB model is designed to withstand a water pressure equal to the height of the slide and can
withstand seating and unseating pressure conditions (bidirectional). Additionally, Orbinox offers a 4
side sealing system for applications having higher water head pressures.
Leakage Allowance:
The leakage rate on the model RB (3 side sealing) is lower than the maximum allowable recom-
mended by AWWA under normal conditions for both seating and unseating head pressures.
AWWA standard leakage rate: 0.1 USGPM per foot of perimeter (1.24 l/min per meter).
ORBINOX standard leakage rate: 0.05 USGPM per foot of perimeter (.62 l/min per meter) under
seating water head conditions, and 0.1 USGPM per foot of perimeter (.62 l/min per meter) under
unseating head conditions
The design and sealing system of the RB Weir Gate model is similar to the MU Slide Gate model.
The main design features are:
Stainless steel fabricated modular design allows for both Open Frame and Self Contained con-
figurations.
Option of Rising or Non-Rising stem configurations.
Option of 3 side or 4 side sealing configurations.
Suitable for actuation with manual, electric, pneumatic or hydraulic actuators.
Self adjusting seal design.
Orbinox Weir Gates are completely factory assembled and tested eliminating the need for on site
adjustment.
Seal Design:
The RB model has a unique self-adjusting seal design, ensuring a substantially watertight perform-
ance. The UHWMPE guides ensure no metal-to-metal contact, reducing the friction during operation
and extending seal life.
