MAC offers a variety of flow ratings, configurations, sizes including two, three, and four-way direct acting, pilot-operated, remote, mechanical valves, and proportional pressure controllers.
Direct acting valve models can handle vacuum pressures to 120 psi and can be operated as a normally open, normally closed, two or three way, selector or diverter allowing the valve to be used in a variety of applications and reducing the need to stock multiple valves
The Balanced design produces precise repeatability regardless of inlet pressure fluctuations - giving consistent machine performance regardless of plant environment.
MAC's rubber bonded spool with smooth finish bore creates wiping action remove contamination from the bore during every valve cycle. This also contributes to very low friction in the bore of the valve.
MAC's patented oval amature creates higher shifting forces over competitive valves of the same size through more core metal and windings.
Low friction and high shifting forces result in a very fast, highly repeatable air valve that can handle contamination. Evidence of this is in the recommended use of 40 micron filtration as opposed to expensive 5 micron filtration recommended for most competitive valves.
The MAC Pulse Valve utilizes the MAC 46 Lifting series balanced pilot technology to ensure fast, repeatable pulses. It also utilizes bonded spool technology in the main valve 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:
High flow direct solenoid operated 3-way poppet valve. It features a short stroke solenoid with oval armature, a balanced poppet and powerful return spring. These features translate into high shifting forces, fast consistent response times, high flow in a small package and long life.
A 3-way balanced spool valve piloted by a small direct operated balanced poppet valve. This is an extremely versatile valve. They can be converted for use in vacuum and it can be changed from an Internal Pilot to an External Pilot function.
he MAC 4-way valves come in direct solenoid as well as solenoid pilot operated for compact size, fast response and high flows. In-line and manifold mount versions are available.
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 Liquid Bullet Valve? is the latest design innovation from MAC. With fast response times, reliable shifting forces and repeatable results - due to its patented balanced design - the MAC LBV is ideal for applications that demand reliable, low-leak performance*. The MAC LBV employs D-Flex? technology to provide an exceptionally tight seal; preventing leakage and saving you product and money.
D-Flex?technology also allows the LBV to last longer and perform stronger in the toughest applications. With fewer wear points than traditional valve technology the LBV is designed to last.
