Overview
The MAC 811C-PM-501JJ-152 is a proven 4-way solenoid-piloted spool valve from MAC Valves’ 800 Series, engineered for responsive pneumatic control in industrial automation and motion control systems. This inline valve combines solenoid actuation with internal pilot operation to deliver smooth, pressure-independent shifting across a wide operating range. The air/spring return mechanism ensures monostable operation—the valve returns to its default state when de-energized, making it ideal for fail-safe applications in manufacturing, packaging, process automation, and fluid power systems.
Key Features
- Solenoid-Piloted Design: Internal pilot air reduces operating pressure requirements while maintaining consistent response times
- 4-Way, 2-Position Configuration: Single solenoid with spring reset enables efficient directional control for double-acting cylinders
- 24 VDC Power Supply: Low-voltage coil (6W) integrates easily with standard PLC and industrial control systems
- Non-Locking Manual Override: Recessed operator allows emergency manual control without defeating safety interlocks
- Robust Construction: Class A encapsulated coil, steel mechanical spring, and muffled pilot exhaust designed for long service life with minimal maintenance
- Compact Inline Mounting: Individual body design simplifies plumbing and reduces panel space requirements
