The CC model is a slide gate designed for open channel installation. Sealing is on 3 sides, (both laterals and bottom). A
perfect sealing is obtained without the need of pressing wedges, due to seal design. Therefore, this model can be used
for modulating purposes, without any water coming out of the partially closed channel section. It is used mainly in water
treatment, irrigation, hydraulic works and hydroelectric power plants.
DESIGN FEATURES
• It is unidirectional as standard. Availability of custom-made
designs for bidirectional aplications in any size.
• Modular design: It allows open frame and self-contained
configurations.
• Option of rising and non-rising stem actuation.
• It is adaptable to lineal actuators as pneumatic and hydraulic
cylinders.
• Standard mounting is embedded inside the concrete channel
walls. A special design for wall mounting is available.
• Sliding pressure pads reduce the friction coeficient, minimize
actuation thrust and extend seal life.
• Stems are in AISI 303 stainless steel. Threading is according
to DIN 103 standard
ACTUATORS
Channel gates are easily adaptable to non-rising stem, rising stem, and lineal actuators: pneumatic and hydraulic
cylinders.
Manual actuators: Automatic actuators:
o Handwheel with rising stem o Electric actuator
o Handwheel with non-rising stem o Pneumatic cylinder
o Gear box with rising stem o Hydraulic cylinder
o Gear box with non rising stem
o Others (square nut,...)
Automatic actuators can be mounted directly on a self-contained frame in case an extension is not needed. When using
extensions, actuators have to be mounted on headstocks or wall supports.
Extensions:
Tube extensions are used to allow operating the slide gate from a distance. Connections to the slide by means of square
nuts or fixed couplings. If the lenght of the extension requires it, fixing to the wall is made by means of wall braquets with
polyethylene guides.
Accesories:
There are various accesories available for the actuators: mechanical stops, actuator manual overrides, locking devices,
solenoid valves, postioners, limit switches, proximity switches, etc.
INSTALLATION INSTRUCTIONS
CC channel gates are designed to be fixed inside the concrete channel walls. There are no parts on the frame that come
out from the inside of the walls. Therefore, dirt accumulation and head loss is minimized.
1. Installation on the channel
• Have the grooves ready on the channel floor and side walls.
Groove size is shown on the drawings.
• Place the channel gate on these grooves with the seals on the
upstream side.
• Centre the frame in the channel, levelling it on both horizontal and
vertical senses. Level the bottom beam of the frame with the channel
floor.
• Fix the slide gate on this position to avoid movement of frame while
filling the groove with mortar. Small channel gates are usually fixed
by means of simple wooden wedges. If the size or weight of the
equipment does not allow to be fixed in such way, the frame will
have special pieces to be fixed to the wall with anchor bolts or
similar.
• Fill the grooves with expansive mortar as SIKAGROUT or similar.
2. Wall mounting
• Open the gate.
• Place the frame against the wall making sure the orifices on both the
wall and the frame are perfectly aligned.
• Drill the concrete using the holes on the body as guiding.
• Introduce the anchor bolts with a hammer.
• In order to avoid leakage between frame and wall, separate the
frame from the wall and fill the void between them with SIKAFLEX 11
FC or similar. As an alternative, sticking soft rubber bands can be
used with an approximate size of 30 mm wide by 15 mm deep,
placed on the frame around the orifice.
• Place the frame back on the wall and tighten the nuts of the anchor
bolts being very careful not to bend it.
WARNING!!
If the wall is not flat, tightening the nuts fully will bend the frame. Use a flat rule while bolting to control the flatness of the
frame. As soon as it starts to bend, stop tightening. Fill the void between wall and metal with expansive mortar, allow
necessary time to dry and retighten all nuts. Malfunctioning of a wrongly mounted slide gate is not responsibility of ORBINOX.
