S LIDE GATE VALVE
D AMPERS IN RANGE
Diverter dampers are available in three configurations: butterfly
tee, multi-louver and flap diverter.
The MSG model Slide gate gatevalve is a square /Round
Three-diverter dampers extend the capabilities of the butterfly
damper design by combining two butterfly dampers into a
common wye or tee fitting, primarily for isolation/bypass
applications. In a wye configuration, diverters can allow
synchronized actuation of each blade for the purpose of splitting
and modulating flow.
port low-pressure valve for highly solid loaded fluids or
solids, mainly used in bulk handling and silo outlet
applications in industries such as:
Isolation of Silo & hoppers Cement industry
A PPLICATIONS Wastewater treatment Plants Power plants Mining
• Stack diversion
• Tempering air
• Flow bypass Food and Beverage Steel industry etc.

STANDARD STYLE ELECTRICAL OPERATOR AND POSITION INDICATORS
Motorised Coffee Pot Damper is tailor made equipment
used in mainly Hot Air Generator to inject cold are
whenever want to reduce gas temp.or also used to take
fresh air in system. These Dampers are operated by
Electrical Liner Actuator.
Gates that use a rack and pinion to control movement of the slide can be ordered with an electric drive to provide for remote
operation. This is accomplished by a . Two Class IIG limit switches are standard and are set to indicate the fully open and fully
closed position of the slide. Separate position indicators are optional for use on any manual, air, hydraulic or standard electrically-
operated slide gate.
Consult the factory for more information on these.
We make a great variety of other sizes that are custom-built to your particular needs and requirements. All hole layouts are based
COFFE POT DAMPER
on our standards and can be changed to meet your specifications. Round inlet plates, square to rounds and companion flanges
are available to help fit these gates into your applications.
SLIDE GATE WITH LINEAR
ACTUARTOR
For isolation purposes, poppet dampers are normally fitted to modular
duct sections.
A pneumatic cylinder drives the damper disc.Each isolation poppet damper
may be operated remotely from the PLC or locally with a lower actuator.
Cylinder mounted limit switches allow PLC indication of damper position.
POPPET DAMER
KNIFE GATE VALVE
The MSKG model knife gate is a uni-directional wafer valve
designed for general industrial service applications. The
design of the body and seat assures non-clogging shutoff on
suspended solids in industries such as:
A pin allows mechanical locking of each damper in either the Open or Closed position. Note: Damper closure only is
not sufficient for internal filter access below the tube sheet. For positive isolation, the slip plate must also be installed.
At all times entry into these areas must conform to confined space entry regulations.
OPTIONS & ACCESSORIES
Dampers can be provided with a wide array of options and accessories
designed to improve performance, automate operation, provide system
feedback, increase safety or create redundancy for critical applications.

DESIGN FEATURES
Miteck Industries offers four seal designs for butterfly dampers:
SWING-THROUGH SEAL
Used in extremely dirty applications where tight shut-off is not required
STEP SEAT
Standard for butterfly dampers. Recommended for
relatively clean flue gas applications, with up to 98%
sealing efficiency
hand wheels or chain falls. Automated actuators include
electric, pneumatic and hydraulic. Electric actuators

2- POSITIONERS AND POSITIONER
FEEDBACK
PNEUMATIC
POSITIONER
-Control dampers require an input signal
to position the blade(s) correctly. Signals
are either electric (4-20 mA), pneumatic (3-15 psi or 3-30 psi) or digital.
Positioners are a required accessory for controlling the location of the
blades beyond full, Open or Close.

Also recommended for relatively clean
applications - when tighter leakage rates are
required
STEP SEAT WITH PERIMETER SEAL
Similar to the step seat, with the addition of an
elastomeric perimeter seal bolted onto the blade.
