WHAT IS THE ROTARY valve?
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 Valves ( Airlocks) are available with square or round inlet and outlet flanges. Housing can be fabricated out of sheet material or cast. Common materials are cast Iron, carbon
steel, 304 SS, 316 SS, and other materials. Rotary valve , airlock feeders are often available in standard and heavy duty models, the difference being the head plate and bearing
configuration. Heavy duty models use an outboard bearing in which the bearings are moved out away from the head plate. Housing inlet and discharge configurations are
termed drop-thru or side entry. Different wear protections are available such as hard chrome or ceramic plating on the inner housing surfaces. Grease and air purge fittings
are often provided to prevent contaminants from entering the packing seals. 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.

A rotary valve is of no use by itself. Rotary valve, airlocks, and rotary valve are useful as one component in a bulk or specialty material handling system. Rotary Valve, Airlocks 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...

While pneumatic transport processes differ according to the phases, it may also diffrent in the same phase. Low pressure, that is dilute phase transfer, can be categorized under 2 classes, namely vacuum and pressure. This classification shows, even slightly, differences in the rotary valve - airlocks. Consequently, we perform manufactures according to the air locks to be used on the vacuum and pressure line.
