Maxon 400CMA11BA11BB22A0 Valve
The Maxon 400CMA11BA11BB22A0 is a heavy-duty 4-inch ANSI flanged gas valve engineered for critical industrial combustion applications. This 2-way normally closed valve features a cast iron body and a CP port flow capacity, making it a rugged solution for high-volume fuel shutoff. Designed as an auto-reset gas shutoff valve, it incorporates Internal Trim Package 1 with Buna-N O-rings and bumpers to ensure a reliable seal in general-purpose gas service. Operating on 115Vac 60Hz for both the solenoid and motor, this unit provides a rapid 6-second motor timing for responsive system cycling. This specific configuration includes the VOS2/VCS2 switch options, providing two extra auxiliary switches compared to the legacy 400CMA11BA11BB21A0 model. Its NEMA 4 enclosure rating ensures environmental protection for the internal components, making it suitable for demanding jobsites where weather resistance and mechanical durability are non-negotiable for safety shutoff requirements.
Key Benefits for Contractors
- Direct Replacement Compatibility: Seamlessly replaces the 400CMA11BA11BB21A0, providing expanded logic capabilities via two additional auxiliary switches.
- Industrial-Grade Sealing: Buna body O-rings and bumpers offer superior resilience in standard gas applications, maintaining seal integrity over long duty cycles.
- Enhanced Enclosure Protection: The NEMA 4 rated housing protects the 115Vac motor and solenoid from dust and moisture infiltration.
- Optimized Flow Dynamics: The CP port design and 4-inch ANSI flange connection minimize pressure drop across the valve in high-capacity burner feeds.
Common Questions
What is the difference between this model and the 21A0 version?
The 400CMA11BA11BB22A0 is the updated version of the 400CMA11BA11BB21A0 and includes two extra auxiliary switches (VOS2/VCS2) for enhanced position feedback and system integration.
Can this valve be used for outdoor installations?
Yes, the NEMA 4 enclosure is designed to provide protection against windblown dust and rain, making it suitable for many outdoor industrial environments.
Does this valve require manual resetting after a power loss?
No, this is an auto-reset model, meaning it will return to its operating state automatically when the control signal and power are restored, provided the safety string is closed.
