Invoit Plast Machinery Pvt. Ltd. Products by Rotary valves for industrial manufacturing are often used in bulk material handling, dust collection, or pneumatic conveying systems, depending on the application. The valve is used to regulate the flow of a product or material by maintaining a consistent flow rate suited to the process. Controlling the flow of material helps to prevent issues such as jamming, material leakage and damage to the valve itself.
Valves are part of the material exchange process and work in metering or feeding applications, function as rotary airlocks, or provide a combination of airlock and metering functions.
A rotary valve in the pharmaceutical, chemical, and food industries is used to dose and feed solid bulk products within the processes. Valves are also commonly used in construction, plastics, recycling, agriculture, and forestry, or wherever material needs to be safely and efficiently conveyed from one point to another.
An airlock-type rotary valve receives and dispenses material from two chambers with different pressure levels. They seal airflow between the valve’s inlet and outlet to maintain a consistent pressure differential, which promotes efficient material flow. The valve’s pressurized chamber prevents foreign material from infiltrating the housing and keeps conveyed material from escaping the system.
A rotary valve (also called rotary-motion valve) is a type of valve in which the rotation of a passage or passages in a transverse plug regulates the flow of liquid or gas through the attached pipes. The common stopcock is the simplest form of the rotary valve. Rotary valves have been applied in numerous applications, including:
- Changing the pitch of brass instruments.
- Controlling the steam and exhaust ports of steam engines, most notably in the Corliss steam engine
Periodically reversing the flow of air and fuel across the open hearth furnace. - Loading sample on chromatography columns.
- Certain types of two-stroke and four-stroke engines.
- Most hydraulic automotive power steering control valves.
Some notable applications of rotary valves are:
- Food and chemical processing applications
- Pharmaceutical manufacturing applications
- Abrasive product conveyance/metering
- Plastics manufacturing
- Frequently cleaned/abiotic applications
- Pneumatic conveyance
