    PULSE VALVE

    Products
    The MAC patented Pulse Valve series was developed to replace current diaphragm style technology and create a more robust and reliable valve solution in industrial applications. MAC Pulse Valves are ideal to replace existing diaphragm technology in applications such as reverse jet bag houses and dust collectors, pneumatic conveying and bulk material handling. The MAC patented Pulse Valve 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 our Remote Bleed version to improve 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. It is currently available in (3) sizes; the PV03, for ¾” and 1” applications and the PV06, for 1 ½” applications, and PV09 for 2' and 2 ½' applications.
