General Description The model VCO-17 is developed in accordance with AWWA C513 Standard and its functions is control and
block the fluid sewage in channels, in a simple and economic way. They are compact and light equipment for
installation directly into concrete with easy operation and water tightness with high versatility and durability.
Designed according to the need of each application, FKB Penstocks are entire provided, including all the
accessories as: fixation kit, extensions, pedestal, sensors, etc., ready to be installed and operated.
Key Features and Benefits
Compact and lightweight;
Versatile production and construction. It adapts to the need of the civil work. (custom-made
manufacturing
Easy and fast installation;
Full passage and free cavity, which eliminates turbulence, pressure drop and possible solids stop on
the penstock or channel;
All components of the penstock are made of 100% Stainless and / or Aluminum material, which
guarantees a long service life;
Low Friction and Self Lubrication Material and Guides, ensuring lightness in operation and NO metal /
metal contact;
Seats and Guides installed in the Drawer, thus allowing easy and quick maintenance, without the
need to disassemble the wall cover;
Built-in or overlapping installation, according to the customer's needs;
Watertightness superior than standards, such as AWWA C561 and DIN 19569, last revision;

Constructive Description
Standard Construction
NBR 8883, AWWA C561, DIN 19569-4 and/or FKB standards/expertise.
All standards are respected according to their last revision.
Sealing Rules
FKB gates are dimensioned and manufactured to meet tightness 100% higher than the adopted construction
standard.
All standards are respected according to their latest revision.
Body Structure
Constructed of flat steel and reinforced, through shaped plates and / or structural profiles, so that it is prepared
for laying or direct casting to the concrete, eliminating the need for a fixing frame.
The Structural Framework can be manufactured as a single piece and rigid enough so that it does not deform
during transportation, installation and operation. Or it can be dismountable and mountable by means of
prisoners, in order to allow easy and quick installation.
Designed and dimensioned in the minimum factor 4 of safety regarding the traction and minimum factor 2 for
the compression and shear.
Penstock (Drawer)
Constructed of flat steel and reinforced, through shaped plates and / or structural profiles, so that the
maximum deflection does not exceed L/720 or 1/16", whichever is less, when the gate is subjected to a
maximum load.
Designed and dimensioned in the minimum factor 4 of safety regarding the traction and minimum factor 2 for
the compression and shear.
Sliding Guides
The guides are made with UHMW (Ultra High Density Polyethylene) and are designed to support 100% the
height of the gate in the fully open position and the NO metal / metal contact, which guarantees low coefficient
of friction, light lifting and eliminates the possibility of its locking and / or misalignment.
Side Sealing
Made of elastomer and UHMW (Polyethylene of Ultra High Molecular Density), in order to guarantee 100%
watertightness superior to the Standards of Construction for long period.
Bottom Sealing (Groundsill)
Made of soft elastomer, the groundsill has the same level of the passage / channel, so that the fluid carries the
solids that may eventually deposit on it. The tightness of the bottom sealing is given due to the compression of
the drawer with the seat against the bottom of the structural frame.
Seat Sealing (When Applicable)
Made of soft elastomer, prepared for laying directly on the concrete without need of fixing frame and assimilate
small deformities of up to 3mm.

Actuation Stem and Extension
Made of Stainless Steel and designed for:
Support the operation of the Penstock under maximum hydraulic load;
Dimensioned in the minimum safety factor 5;
Designed to transmit at least 2 times the output torque of the manual mechanism and 1.5 times the
output torque of the Electric, Hydraulic or Pneumatic Actuator.
Notice:
Penstocks which have a width of more than 1,200mm and a height of less than half its height shall be
fabricated with a Double Tandem Shaft System, from which it shall ensure single and simultaneous drive by
both shafts, and shall not allow misalignment and displacement of the drawer during its operation.
Gloves (Actuation and/or Extension Stem Connections)
Made of Stainless Steel, in order to make the connection of the stems and avoid any possibility of rotation or
locking.
Intermediate Bearing
Made of Stainless Steel, to ensure perfect alignment of the stem, penstock and drive, and avoid any possibility
of buckling of the extension stem.
Actuators
Hand Wheel: Designed to operate the penstock under maximum pressure with application of manual effort in
the mechanism up to 18.15 kgf (178N). In case of using Gear Box, it will be sized for the force, at least, 1.5
times of the maximum torque required for opening and / or closing the sluice under maximum pressure.
Pneumatic Actuator, Hydraulic or Electric: Designed for the force, at least, 1.5 times of the maximum
torque required for opening and / or closing the sluice under maximum pressure.
Note: Other actuators on request
