Welcome to your brand new MAC VALVES catalog. Inside you will find more than 25 different valve series to meet the majority of industrial requirements. They have been sorted and classified in such a way that you may easily find the required valve series. For more than 50 years, MAC has based all new valve developments upon the specifications received from customers, both users and OEM’s. A lot of different modifications have been released for all fields of industry (automotive, aluminium, packaging, food, sorting, ...). Although they are not listed in this catalog, our technical sales staff...

Introduction MAC Valves 18 month guarantee plus lifetime coil guarantee The MAC Valves organization has established a reputation over many years for fulfilling the needs and requirements of the users of its products. All MAC Valves are quality products specifically designed and built for long and rugged service. Therefore, all valves appearing in this catalog are guaranteed for a period of eighteen months from the original date of shipment from our factory. In addition to this eighteen month Guarantee, MAC Valves, Inc. guarantees the electrical coils on every one of the valves listed in...

SPOOLS/BODIES PRESSURE SIDE MAC flow seals are bonded to an aluminum spool, machine ground to a very close tolerance, and chemically surface hardened. The bore of the bodies is finished to a close tolerance, work hardened and polished. The result of these processes on the spool and bore keeps friction to a minimum and provides wiping action thus assuring long, stick-free consistent operation and making the spools relatively unaffected by air line contaminates. MAC spools are of a balanced design; therefore they are not affected by back pressure or restrictions in the exhaust, permitting...

VIRTUALLY—BURN-OUT PROOF MACSOLENOID® The patented spring biased floating pole piece MACSOLENOID® used on all 3-ways and 4-ways in this catalog is independent and isolated from the valve body (100 Series shown above). When voltage is applied to the coil, the pole piece is held down by the bias spring so that the magnetic attraction between the pole piece and armature results in the armature moving down against the push pin, moving the poppet from the Normally Closed (N.C.) seat to the Normally Open (N.O.) seat. After the poppet has shifted completely, the pole piece then moves upward,...

ELECTRICAL PLUG-IN CONNECTIONS 4-way plug-in models incorporate recessed, shrouded connectors in both body and base with an integral ground pin that makes connection first and breaks last. Plug-ins permit easy and fast replacement of the valve without disturbing either the elecrical wiring or air plumbing. Let us show you via high performance demonstration kits and animated software, HOW MAC’S PERFORMANCE ADVANTAGES HELP MAKE YOUR EQUIPMENT MORE RELIABLE - FASTER - MORE REPEATABLE. Traveling Lab Demonstration measures critical valve performance characteristics - Shifting forces, Response...
