Overview
The MAC 45A-AA2-DDAJ-1KJ solenoid valve is a compact, direct-operated 4-way poppet valve from MAC’s proven 45 series. Rated for 24VDC (5.4W) operation, this single-solenoid unit features integrated directional flow controls and manual override capability, making it suitable for pneumatic and fluid power applications requiring precise, repeatable flow direction control.
Key Features
- Direct Solenoid Operation: Direct solenoid operated with short stroke solenoid and balanced poppet design
- Fast Response & Long Life: High shifting forces and fast consistent response times with long service life
- Balanced Poppet Design: Immune to pressure variations; supports versatile piping configurations (4-way, 3-way, 2-way, diverter, selector)
- Manual Override: Non-locking recessed manual operator for emergency actuation
- Integrated Flow Controls: Pre-installed directional control cartridges for simplified installation
- High Cycle Capability: Rated for continuous-duty, high-cycle pneumatic and fluid control applications

Replaces / Drop-In Replacement For
Verify compatibility with your system integrator or equipment OEM before ordering. Similar 45 series models (e.g., 45A-AA1-DDAJ-1KJ, 45A-AA2-DDAJ-1KA) share core architecture but vary in operator configuration and flow control integration.
Works With
- Pneumatic flow control circuits (FRL — Filter, Regulator, Lubricator)
- Proportional and directional solenoid valve pilots
- PLC and automation control relays rated 24VDC
- Standard pneumatic quick-disconnect and threaded port adapters
