Guillotine damper are typically specified for gas shut-off of ducts and they are commonly installed in furnaces, heaters, reformers and other chemical and petrochemical application or cement industry as well as isolators downstream diverters in GT exhaust systems or any other heavy duty industrial application. Guillotine damper employ a sliding blade inserted into the duct from an external frame to block flow in rectangular and round ducting. Guillotine damper provide a mechanized means of inserting a duct blanking plate and offer superior isolation of flue gas applications containing heavy particulate loads and are ideal for tight shut off applications.

Butterfly dampers are typically used to intercept or regulate gas flows; they are similar to single-louver dampers with one blade and they can be used in round or square/rectangular ducts. Blade is typically designed with air-foil configuration which minimizes the pressure drop; shafts are made of solid section and “stub” type to be connected to the blade by keys and blocks. This basic rule of design will optimize the assembly operations reaching high accuracy; in addition, in case of need, the blade can be removed from the damper frame without removing the complete unit from ductwork. Actuation system is normally by electric actuator, pneumatic actuator or manual by irreversible gear box.Butterfly dampers can be supplied with internal or external fiber insulation or, when required, with internal concrete (refractory) insulation. A large variety of metals are used in design and fabrication, from simple carbon steel to stainless steel and low-alloy/high-alloy materials.

Material flow diverter is used for selecting one out of two outlet ports. The flow through these valves is essentially a gravity flow and the position of the diverter flap decides which of the two outlet ports will be active. MITECK SYSTEMS manufactures & supplies these fabricated valves as per customers’ requirements. Diverter valves are designed to direct product flow outlets of storage bins, silo conveyors, gravity flow chutes and other discharge points handling powders, granules, grains and other bulk solids. These valves are available in deflector or diverter types, with three-positional control on diverter if required to split the flow. The splitting of flow can be achieved by positioning the diverter flap in an intermediate position. However, middle position will not necessarily mean equal splitting of flow as the location of valve and material flow characteristic can influence the flow splitting ratio.

Basic application of self cleaning Rotary valve is used where material is having tendency to stick to rotor blade pockets, These valves are designed in such a way that it scrap our material at each revolution at the discharge point. Miteck systems self-cleaning-rotary valves convince with enforced cleaning with help of scrapper, which ensures a proper discharge of sticky material at each revolution of rotor A scraper blade rotor mounted below the rotor is driven with the help of a synchronization gear. For metering, sealing, feeding and discharging as well as measuring of bulk-solids in sticky, bridging and moist conditions, which tend to cause blocking, such as coal, salts, ashes, limestone, slurries and methyl cellulose. Base of this design is our standard Rotary Valve. The forced cleaning ensures a correct discharge of every kind of material, which wouldn’t be possible with a standard model.
