Overview
The MAC 45A-AA1-DAAA-1CM is a direct solenoid-operated 4-way poppet valve from MAC’s proven 45 Series product line. Rated for 120VAC operation at 60Hz, this valve features 1/8″ NPT female threaded ports and a monostable (single-solenoid) design with manual override. Designed for pneumatic and inert gas applications, the 45A-AA1-DAAA-1CM delivers repeatable performance in motion control, automation, and fluid power systems.
Key Features
- Direct solenoid actuation with short-stroke design for rapid, consistent response
- Balanced poppet and conical seat design for high shifting forces and long service life
- Monostable operation with mechanical spring reset
- Non-locking recessed manual operator for emergency control or manual cycling
- Four 1/8″ NPTF female pneumatic ports (A, B, EXH, IN) for flexible piping configurations
- 1/2″ NPS metal conduit connection with 18″ flying lead wires
- Versatile 4-way/3-way/2-way piping configurations for diverter, selector, or standard directional control applications
- Compatible with vacuum to 120 psi pressure range

Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. This part number variant (45A-AA1-DAAA-1CM) is the 120VAC version; units with other voltage codes (e.g., 45A-AA1-DAAA-1CA for 110Vac, 45A-AA1-DDAA-1CM for 24VDC) are not direct functional equivalents.
Works With
- MAC 45 Series manifold blocks and cavity porting systems
- Pneumatic control circuits (single solenoid, spring return topology)
- Industrial PLC and relay-based automation systems
- Standard 120VAC control panels and enclosures
- Manual valve control and override systems
