Why MAC Valves beat diaphragm technology for dust collection, bulk handling, reverse jet baghouses and pneumatic conveying


What industries can MAC Valves be used in?

MAC Pulse Valves were developed to replace current diaphragmatic style technology and create a more robust and reliable valve solution in industrial applications such as:

  • reverse jet baghouses
  • dust collectors for concrete and grain
  • pneumatic conveying
  • bulk material handling

MAC Valves have successfully improved:

  • air quality
  • system reliability
  • productivity

in these industries:

  • Automotive

  • Primary Metals

  • Gypsum

  • Cement Plants

  • Glass Sorting

  • Aluminum

  • Chemicals

  • Zinc Refinery

  • Tires

  • Pharmaceutical

  • Food Processing

  • Agricultural Processing

  • Power Plants

  • Wood processing

Why are MAC Valves designed to replace diaphragm technology?


  1. Air leaks prevented

Spool valves are more reliable than diaphragm ones as the valves prevent air leaks. This lowers the cost of ownership through a reduction in downtime. Diaphragm-based valves often start to leak within a few weeks of installation and fail open, because they are damaged by processes such as thermal cycling


  1. Clogging is no longer a problem

Diaphragm valves have a small, fixed orifice that clogs easily, resulting in sticking, burning, inconsistent air pulses and filters clogging with dust. This increases maintenance work as the filters need to be changed more often. The valves are typically only rated for approximately 1 million cycles. MAC Valves are rated for 10 million cycles.


  1. MAC Valves don't stick

This is because of the high forces that are achieved with the valve’s short stroke.
