Overview
The MAC 45A-MAJ-DDAJ-1KJ solenoid valve is a direct solenoid operated 4-way poppet valve designed for high-reliability pneumatic control applications. The MAC 45 Series features a short stroke solenoid, balanced poppet and conical seats that translate into high shifting forces, fast consistent response times, and long life. The 45A model is compact, feature-rich, and ideal for automation equipment requiring fast cycle rates and durable valve operation.
Key Features
- Patented MACSOLENOID for fastest possible response times with bonded balanced poppets for high flow precision and repeatability
- Valves can be piped as 4-way / 3-way or 2-way / normally closed or normally open or used for vacuum / diverter / selector applications
- Extremely high cycle rates and extremely long service life due to unique poppet cushions
- Use on lube or non-lube service
- Manual overrides as standard
- Patented MACSOLENOID virtually burn-out proof on AC service
