Rotary Air Lock Valve – Working, Use and Application

Rotary air lock valves are used in an extensive range of applications where there is a need to reduce system air losses while shifting material from one vessel to other with different pressures. These are also essential components of bulk solids handling, pneumatic conveying and batching systems. These are referred by many different names. Some are suitable and some are not. Some universally accepted names include rotary feeder, rotary valve and airlock feeder. The main function of it is to control flow of bulk solids from hopper, cyclone, mixer, or silo under pressure, gravity and vacuum conditions. These are available in a range of sizes and capacities as needed by people.

These kinds of valves have wide application in industry wherever granules, dry free-flowing powders, pellets, or crystals are used. For example, it is used in pharmaceutical industry, sugar industry, cement, plastics, cereals, flour and mineral industry also. These feeders are also perfect for pollution control applications in paper, wood, grain, textile, food, rubber, paint, and tobacco industries. Rotary valves from standard series work underneath cyclone separators and dust collectors even with high temperatures and different pressure differentials.

Rotary feeders are available with round or square inlet and outlet flanges. These are mainly composed of cast or sheet material. Other materials which are used in its manufacturing include carbon steel, cast iron, 316 SS, and 304 SS. Rotary air lock valves are often obtainable in heavy duty and standard models. These differ from each other bearing configuration and the head plate.

Rotary airlock feeders are mainly of two types; drop through and drop through. The blow-thru feeder is perfect for pneumatic conveying applications in chemical, grain, food, baking, plastics, milling and pharmaceutical industries. It features a low profile with large capacity. Drop through one is designed for rugged applications that require an outboard bearing style unit where abrasive product and /or contamination cannot be handled with an inboard bearing style. These are engineered for use in highly pressured pneumatic conveying systems, where more of an effective seal is essential because of high or excessive wear that come with a simple dust collector.

Know More About Utility of Rotary Air Lock Valve

Rotary air lock valve is also well-known as rotary feeders and is commonly used in agricultural as well as industrial applications as one of the important component in specialty or bulk material handling system. Their primary use included discharging bulk solid material from bins, receivers and hoppers into a vacuum-driven pneumatic conveying system.

Their common applications basically include gravity discharging/conveying and pneumatic conveying. Owing to these applications, they are commonly used with storage bins, baghouse hoppers and dust collection systems. The seal of this style of airlock valve is more suitable for low and moderately pressurized systems where small air leak is adequate.

Apart from this rotary air lock valve is also used in volumetric feed controls and dust control equipment. To describe more precisely, it has vanes that perfectly fit closely against the valve walls. When the vanes turn, it allows materials to pass through it without creating a direct opening between the outlet and inlet sides of valve. This airlock quality of rotary value contributes towards its usefulness.

Vanes present in rotary airlock valves are operated by making use of motor. The volume of material which can be moved in vanes can be measured by the vanes rotation. You can adjust the speed of the motor so as to increase/decrease the material flow rate in valves.

Following are some essential considerations for rotary airlock valves:

• The construction of the steel body, whether it is cast or plate steel

• Number of vanes in the airlock valves

• The size of opening in rotary valve

• Motor’s capability and size

• Type of material used to tip the vanes i.e. whether it is hardened or rubber steel

You can refer to several relevant sources online to get in-depth information about uses, applications and importance of rotary airlock valves.
