Replaces / Drop-In Replacement For
Verify compatibility with your system integrator before ordering. The MAC 825C-PM-591JM-652 is designed as a direct replacement for earlier 825C-PM series valves with identical port configuration, solenoid voltage, and mounting footprint. Common equivalent part numbers may include variants ending in different pilot connector or solenoid codes (e.g., 591-series with JM pilot type). For specific interchangeability, consult MAC Valves engineering documentation or your distributor.
Works With
- Pneumatic flow control systems and proportional valve stacks
- Industrial PLC and automation controllers via 24VDC solenoid interface
- ISO/IEC pneumatic component standards
- MAC integral or external exhaust flow control accessories
- Low-pressure pilot supply systems (no external air required)
