Do not expect the solenoid to operate correctly if the outlets are not connected to the system.
Many solenoids will not shift correctly without correct air pressure and back pressure. Make sure the shut off valve is completely open.
Make sure the machine receives the correct air pressure and flow. The MAC Liquid Valve line of products is designed to last longer and perform stronger in the toughest applications. These valves also work great in pneumatic applications that require leak tight performance. Proportional Flow Controls (PFC’s), Flow-Thru valves, Single and Dual Diaphragm (Media-Separated) valves, Wetted Solenoid valves and Dosing Fluid Pumps are a few of the product offerings in MAC’s liquid valve family of products. Fast response times, reliable shifting forces and repeatable results are just some of the benefits you can expect from our fluid line of products. The MAC Liquid Valve line of products benefits from many of the same innovative features and associated benefits that have become synonymous with MAC’s performance characteristics over the years. Reliable operation in extreme environments. Wetted and non-wetted (media-separated) solenoids. 2-way, 3-way, variable flow, filling and dosing valves. MAC PV03 Brochure MAC PV06 Brochure MAC PV09 Brochure MAC PV12 Brochure MAC Pulse Valve Technical Paper MAC Pulse Valve ATEX 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. A line of adapter plates has also been released to replace existing diaphragm pulse valves with a direct drop-in, without disturbing existing plumbing. 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. The main body of the MAC Pulse Valve utilizes bonded spool technology for superior reliability beyond existing diaphragm technology. 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. 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 series was developed to replace current diaphragm style technology and create a more robust and reliable valve solution in industrial applications.
