ROTARY VALVES

TRotary valves are composed of 4 main components: an outer housing, a rotor, a rotor bearing and seal, and a drive.

Rotary valves are used in almost all pneumatic conveyor systems, but they also find uses in many other applications. This section will display just how indispensable these valves are, and how they can still find new uses

How the AIRLOCK Rotary ValveS WORK?


When performing transfer on all pneumatic conveying lines, it is a device to feed the material down to the line and separate the raw material pneumatically transferred from the air. Blade forms, tolerances, revolution speeds vary depending on type of process and type of the product to be transported. Likewise, it may also act as breaker depending on the characteristics of the material to be transported. Even it may also operate coupled with the breakers.Rotary Valve AIRLOCKs are designed for use under gravity,pressure and vacuum conditions.

What IS A Rotary Valve?


It is a compact mechanical device for continuously discharging  bulk powders or granules under gravity flow. By definition it is the simplest of machines having only one moving part (ignoring the drive); a multi-vane rotor revolving in close contact in the housing and where the housing has an inlet at the top, and an outlet at the bottom.


Rotary Valve - AIRLOCKs - Star Feeder may be made of ST37 Carbon Steel and AISI-304 AISI-316 Stainless Steel. Bedding types of the AIR LOCKs may be mechanical sealing and felt, again depending on the hot process.

Rotary Valve - Ailock-Star Feeder internal Rotors have options such as blade, rounded type, adjusted blade type, stripper and polyamide.

Rotary Valve - AIRLOCK – Star Feeder That the Cell Wheel has that many options is completely related with type of material to be transported as well as process. This is so vital that a single fault may give damage to the material to be transported. Simple solution commercially available may deliver successful results for transfer of many materials such as flour, cement and many more. However, a slight change in the granule size and a different material means fail of such equipment.
 
Rotary Valve ,  AIRLOCK Function
Our Rotary Valves, designed according to a criteria of maximum applicative
universality, are suitable for controlled feeding or discharging of products in powder or
granular form, from silos, hoppers, pneumatic conveying systems,high temperature process, bag filters or cyclones.

Rotary Valve Connection Types
How will the valve connect to your larger system, and how will it feed and discharge? These are all important specifications, as different feeding and discharge equipment can be used to differing successes. There are hopper feeders, blowers, simple piping, and other equipment, so figure out which one will be used in your project. Specifying these aspects will also allow you to find a rotary valve that will come with the correct connection characteristics for your greater application such as welding spots, through holes, etc.

Why Choose a DOSERAY Rotary AIRLOCK?

Air Filtration provides a complete line of rotary valve - AIRLOCKs suitable for AIR LOCK applications ranging from gravity discharge of filters, rotary valves, cyclone dust collectors, and rotary valve - AIRLOCK storage devices to precision feeders for dilute phase and continuous dense phase pneumatic conveying systems. Rotary Valve / AIRLOCK Feeders are used in pneumatic conveying systems, dust control equipment, and as volumetric feed-controls to maintain an even flow of material through processing systems. The basic use of the rotary valve, AIRLOCK feeder is as an AIRLOCK transition point, sealing pressurized systems against loss of air or gas while maintaining a flow of material between components with different pressure. Rotary Valve, AIRLOCK Valves are also widely used as volumetric feeders for metering materials at precise flow rates from bins, hoppers, or silos onto conveying or processing systems.

Blow ThrOUGH Rotary Valves

A rotary valve is of no use by itself. Rotary valve, AIRLOCKs are useful as one component in a bulk or specialty material handling system. Rotary Valve, AIRLOCK Feeders have wide application in industry wherever dry free-flowing powders, granules, crystals, or pellets are used. Typical materials include: cement, sugar, minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee, cereals, pharmaceuticals, etc...
