The MAC 45 Series is a direct solenoid operated 4-way poppet valve. It features a short stroke solenoid, a balanced poppet and conical seats. These features translate into high shifting forces, fast consistent response times, and long life. For information regarding certifications (such as UL, CSA, RoHS and CE) please visit the Get Support pages on our website.
Large 4-Way Valves. MAC 4-way valves offer solenoid pilot operated, air pilot or manual operation. Their balanced spool means the valve can be piped as a 4-way, 3-way, 2-way, normally closed or normally open or can be used for vacuum, diverter or selector applications. Our one piece bonded seal spool means longer life and easy maintenance.
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. At MacDon, our reputation is driven by quality, reliability and our passion for exceptional customer support through listening and responding. Please contact your Dealer’s Service Department with any problems or concerns that you may be experiencing with your equipment.
