Valves are important devices which regulate the flow of fluids or gases in a pipeline traversing from source to destination, and ensure the flow rate and speed are as required. These are electronic or electromechanical devices. Rotary valves are pneumatic devices which control the flow and transfer solids such as powders or granular material source to destination in a manufacturing setup. These devices serve as airlocks and hence reduce air pressure losses. JM Industrial stocks various types of used rotary valves for sale. If you have any questions, please contact us.

Types of Unused and Used Rotary Valves at J&M Industrial

At JM Industrial, we provide various types of used rotary valve for sale, including the sizes are 8 inch, 10 inch, 10" X 10" inch, 11.25" X 6.5" inch and more.

  • Housings: We offer valves with offset and inlet housings. In offset type, the inlet and outlet are arranged in a skewed manner to prevent overfilling. In inline housings, the inlet and outlet are placed one above the other. This is a more practical arrangement compared to offset which is suitable for specific applications.
  • Rotors: These are of various types such as open, closed, staggered pocket, radius pocket, adjustable, metering, and so on. The number of rotors is same as the number of vanes.
  • Drives: Rotary valves are driven by various types of motors depending on the size, such as hydraulic for large valves and synchronous electric for most other types. Most of our rotor valves are made of stainless steel or carbon steel and have reduction gearbox with a chain setup connected to an electric motor.
  • Airlock Valves: Usually made of stainless steel, these valves do not require a rotor or gearbox. They have a solid metal housing, plain or beveled rotor tips, outboard bearings with air-purged seals, and so on.

Factors to Consider When Select the Right Rotary Airlock Valve for Your Application

When choosing the right used rotary airlock valve for your application, there are several factors to consider. Here are some of the most important ones:

  • Material Type and Characteristics: The type, size, shape, density, and flow properties of the material being handled can affect the valves performance and longevity. Make sure to choose a valve that is designed to handle your material and its characteristics.
  • Valve Size and Capacity: The size of the valve should be appropriate for the required capacity and the size of the feeder or hopper. Choose a valve with a capacity that meets or exceeds your needs to avoid overloading or underutilizing the valve.
  • Operating Conditions: The operating conditions, such as temperature, pressure, and environment, can impact the valves performance and durability. Make sure to choose a valve that can withstand the specific operating conditions of your application.
  • Material of Construction: The valves material of construction should be compatible with the material being handled, as well as the operating conditions. Common materials include carbon steel, stainless steel, and exotic alloys.
  • Design Features: Different valve designs offer different features, such as air purging, self-cleaning, anti-leakage, and explosion-proof. Consider which design features are most important for your application and select a valve that offers those features.
  • Maintenance Requirements: Maintenance is an important aspect of valve performance and longevity. Choose a valve that has maintenance requirements that match your available resources and expertise.

Rotary Airlock Valves in Dust Collectors: Causes and Solutions

Industrial used rotary airlock valves are essential components in dust collection systems. However, several issues can arise with these valves, leading to performance and maintenance problems. Here are some of the most common issues with rotary airlock valves in dust collectors, their causes, and solutions:

  • Leakage: Leakage in rotary airlock valves can occur due to improper sizing, material buildup, or worn-out seals. This can lead to performance issues and dust emissions. To solve this problem, make sure to choose the right valve size and material, clean the valve regularly, and replace worn-out seals.
  • Clogging: Clogging in rotary airlock valves can happen due to material bridging, agglomeration, or adhesion. This can lead to reduced throughput, valve damage, and system downtime. To prevent clogging, use proper material handling techniques, install a material agitation system, and choose a valve with self-cleaning features.
  • Wear and Tear: Wear and tear in rotary airlock valves can happen due to abrasive material, improper use, or lack of maintenance. This can lead to valve failure, reduced lifespan, and increased maintenance costs. To prevent wear and tear, choose a valve with wear-resistant materials, follow proper operating procedures, and conduct regular maintenance.
  • Jamming: Jamming in rotary airlock valves can occur due to foreign objects, oversized material, or inadequate clearance. This can lead to system downtime, valve damage, and safety hazards. To prevent jamming, install a metal detector or a magnet to catch foreign objects, use a properly sized valve, and maintain the clearance between the valve and the inlet.
  • Overloading: Overloading in rotary airlock valves can happen due to excessive material flow, undersized valves, or improper use. This can lead to valve damage, system failure, and safety hazards. To prevent overloading, choose a valve with the appropriate capacity, monitor the material flow rate, and follow proper operating procedures.

By understanding and addressing these common issues, you can ensure optimal performance, lifespan, and safety of your rotary airlock valve in your dust collection system.
