Overview
The MAC 45A-AA1-DDAJ-1TA is a direct solenoid-operated 4-way poppet valve from MAC Valves’ proven 45 Series. This compact, electronically actuated control valve operates at 24VDC with a 5.4W power consumption. The unit delivers precise pneumatic and vacuum control in a single, integrated package suitable for industrial automation, machine control, and motion applications requiring rapid response and long service life.
Key Features
- Direct Solenoid Operation: Patented short stroke solenoid with balanced poppet and conical seats for high shifting forces and fast response
- 4-Way, 4-Port Configuration: Individual in-line installation with 4 × 1/8″ NPTF threaded female pneumatic ports (A, B, EXH, IN)
- Monostable Operation: Steel mechanical spring reset with non-locking recessed manual operator for fail-safe control
- High Flow & Precision: Bonded balanced poppets for high flow, precise repeatability, and consistent operation
- Extended Cycle Life: Unique poppet cushions provide extremely long service life
- Flexible Piping: Balanced poppet design permits operation as 4-way, 3-way, or 2-way, normally closed or normally open, or for vacuum, diverter, or selector applications
