Overview
The MAC 45A-MAJ-DDAJ-2KJ is a direct solenoid-operated 4-way poppet valve designed for pneumatic control applications. Part of MAC’s 45 series, this valve combines compact size with reliable performance in automated assembly, material handling, and process control systems. The unit features balanced poppet and conical seat design for high shifting forces and fast, consistent response times.
Key Features
- Direct Solenoid Operation: Patented short-stroke solenoid with high shifting forces
- 4-Way / 2-Position Configuration: Routes pneumatic flow in monostable (spring reset) operation
- Balanced Poppet Design: Immune to pressure variations; enables versatile piping arrangements (4-way, 3-way, or 2-way)
- Locking Manual Operator: Emergency manual override with locking recessed control
- Manifold Sub-Base Mounting: Integrates with standard pneumatic manifold systems
- DIN 43650 Connector: Male square electrical connection for solenoid coil
