Overview
The MAC 411A-A0A-DM-DFFJ-1KJ is a 5/2-way spool valve assembly from MAC Valves’ proven 400 series. This solenoid-piloted, spring-return (monostable) configuration delivers repeatable, responsive pneumatic switching for industrial automation, material handling, and machine controls. The unit is rated for 20–120psi compressed air operation and incorporates internal pilot air for efficient actuation with minimal pilot line pressure loss.
Key Features
- 5/2-way, 4-port configuration with single solenoid operator and spring reset
- Patented MACSOLENOID technology for rapid response times and burn-out resistance
- Non-locking recessed manual override for emergency or manual control
- Internal pilot air reduces auxiliary pilot line complexity
- Muffled pilot exhaust minimizes noise in compressed air systems
- Flow coefficient (Cv) of 1.0 for controlled, metered flow
- Mini plug-in DIN 43650 connector with built-in diode and indicator light for coil status visibility
Technical Specifications

Typical Applications
- Pneumatic automation circuits requiring 4-way, 5/2 valve logic
- Double-acting cylinder control (single solenoid forward, spring return)
- Pick-and-place, material conveying, and assembly line equipment
- Industrial packaging machinery
- Machine tool air controls
- Pneumatic press and clamp operations
- OEM and retrofit installations where compact, responsive piloted control is needed
Compatibility & Replacements
Compatible With
