Selection Guide For Valves For Solid & Bulk Handling


It is the mistake of people who think that selecting a slide gate or diverter for managing dry material is a simple process. Diverter valves manufacturers often receive such queries in which the customer asks different yet incomplete things. Clients often assume the only information they require is –

  • Size of the opening
  • Available stack-up height
  • Shape of the opening
  • Matching connections or hole patterns

But manufacturers require more details to precisely select the right valve for your application. You can easily avoid costly mistakes by giving right and complete information about the application parameters. It is must that the supplier you select should have experience and knowledge about valves.

Significant factors that determine the type of valve for selection are –

  • Function
  • Operation
  • Costing

Once you get the answers for these, you can start questioning your valve supplier –

  • What is the opening or orifice size?
  • Is the opening round or square?
  • Will the valve be installed outdoor or indoor?
  • Will the valve be applied in a pressure or gravity application?
  • What is the temperature of the air and material conveyed?
  • Does the system apply dilute, phase, vacuum, dense phase, or gravity to convey material? In case of vacuum or pressure, how much?
  • Are the lines pipe or tube?
  • Does the valve need to be made of stainless steel, carbon steel, aluminum, or brass?
  • Will the valve be subject to wash down? If yes, will it be washed with a caustic liquid or hot water?
  • What is the operations’ sequence for the system?

How To Diagnose A Faulty Boiler Diverter Valve

You have to consider the material characteristics once you get the answers-

  1. What is the material to be conveyed?
  2. What is the particle size?
  3. Is the material available in granular, powder, or pellet form?
  4. What is the weight of the material per cubic foot?
  5. Is there spoilage or sanitary issues with the material?
  6. Is the material abrasive, sticky, or corrosive?

You can talk to manufacturing experts and determine if their valve offers standard modifications to suit material specific requirements.

Some specific factors to consider for valve modifications are-

  1. Abrasive duty
  2. Particle size
  3. Corrosion
  4. Chemical compatibility
  5. Temperature
  6. Food specific
  7. Indoor or outdoor service
  8. Friability

Contact diverter valves manufacturers and ask for personal assistance to select the right valve for your application.
