Fast, Repeatable and Reliable Pulses for Dust Collection

MAC’s patented bonded spool technology is transforming the dust collection industry. The MAC Pulse Valve was developed to replace current diaphragm style technology and create a more robust, reliable and environmentally conscience valve solution. MAC Pulse Valves are designed for lowest cost of ownership, long life, and configurable to most any existing baghouse.

MAC Pulse Valves can be ordered in one of two pilot configurations: The Integral Solenoid pilot combines fast, repeatable pulses with the addition of a Manual Operator, while MAC’s Remote Bleed version improves performance and reliability in hazardous locations. The main body of the MAC Pulse Valve utilizes bonded spool technology for superior reliability beyond existing diaphragm technology. A checked accumulator and a main spool with memory spring are used to ensure a shift back to the home position, for times when air supply may not be adequate. A line of adapter plates has also been released to replace existing diaphragm pulse valves with a direct drop-in, without disturbing existing plumbing.

The Problem with Diaphragm Valves

The drawbacks of outdated diaphragm style technology include high energy consumption, routine maintenance and requires higher pulsing frequency for cleaning.

The valve for the far-left filter failed and was replaced with a MAC Pulse Valve. The image shows the result after just 2 cycles.

Benefits of a MAC Pulse Valve:

  • Energy Consumption

    Energy savings for replacing diaphragm valves with a spool valve can be 20 – 70%

  • Maintenance
    Lower cost of ownership through reduction in downtime due to high reliability. When necessary, maintenance is simplified with available spool kits
  • ROI
    A fast return on investment is due to significant energy savings, extended bag life, greatly reduced replacement costs, reduction in downtime and labor savings

  • Harsh Environment Compatible
    An aluminum die-cast body, nitrile seals and an environmentally protected solenoid are standard features
