Overview
The MAC 411A-A0A-DM-DFFJ-1KJ solenoid valve is a 4-way, 5/2 directional control spool valve designed for pneumatic system actuation in industrial automation. Rated for 20–120 PSI operation, this 24VDC solenoid-pilot-operated valve provides precise directional control for cylinders and pneumatic motors. MAC’s 400 Series delivers fast response times with internal pilot air operation, making it ideal for manufacturing, packaging, and motion control applications.
Key Features
- 4-Way, 5/2 Configuration — Provides forward, neutral (center-to-tank), and reverse flow paths for bidirectional actuator control
- 24VDC, 2.4W Solenoid — Low-wattage DC coil with indicator light; operates without external pilot supply
- Internal Pilot Air — Self-piloting design leverages system pressure for smooth spool shifts
- 1/8″ NPTF Ports — Standard ported connection (5 stations: P, T, A, B, X) for inline mounting
- Non-Locking Manual Override — Recessed manual operator allows emergency directional actuation without electrical input
- Compact, Lightweight Design — Only 0.30 lbs; fits confined panel and manifold spaces

Replaces / Drop-In Replacement For
- MAC 411A-A0A-DM-DFFJ-1KD (same 1/8″ NPTF, 24VDC; 1KD uses different wire connector)
- MAC 411A-B0A-DM-DFFJ-1KJ (mechanically similar; verify coil orientation and electrical specs)
- Verify compatibility with your system integrator or valve supplier before ordering replacement units
Works With
- Control Platforms: PLC ladder logic, relay circuits, discrete 24VDC solenoid drivers
- Communication: Standalone direct-wired solenoid actuation (no fieldbus required)
- Manifold Systems: Sandwich and modular cavity stacks using ISO 4401 (CETOP) cavity patterns
- Safety Systems: Emergency stop circuits (manual override for fail-safe depressurization)
