Maxon 125SMA11AA11BB22A0 Gas Valve
The Maxon 125SMA11AA11BB22A0 Gas Valve is an industrial-grade, 1 1/4-inch normally closed safety shut-off valve designed for critical fuel line applications. Built with a rugged cast iron body and high-performance Buna-N o-rings and bumpers, this electromechanical gas valve ensures a bubble-tight seal that meets ANSI/FCI 70-2 Class VI seat leakage standards. Engineered for automatic reset functionality, the valve utilizes a 115VAC 60Hz motor with a precise 6-second motor timing to manage flow effectively in general-purpose environments. The internal Trim Package 1 is optimized for clean fuel gases, while the NEMA 4 enclosure rating provides robust protection against moisture and debris in demanding mechanical rooms. This 2-way gas shut-off valve features VOS2/VCS2 switch options, providing reliable proof-of-closure and proof-of-open signals for integration into modern burner management systems and flame safety circuits. Technical professionals specify this safety shut-off valve for its 100 PSIG maximum operating pressure differential and its ability to fail-safe immediately upon power loss.
Key Benefits for Contractors
- Internal Trim Package 1: Engineered for durability with standard fuel gases, ensuring long-term seat integrity without frequent maintenance.
- NEMA 4 Protection: The heavy-duty housing protects internal electrical components and switches from washdowns and harsh industrial environments.
- Proof of Closure/Open Switches: Equipped with VOS2/VCS2 switches to provide essential feedback to control panels, confirming valve position for safe sequencing.
- Standard Port Flow: The 1 1/4-inch ANSI threaded body maintains high flow capacity with minimal pressure drop across the valve.
Common Questions About the Maxon 125SMA11AA11BB22A0
Is this valve suitable for outdoor installation?
Yes, the NEMA 4 rating ensures the actuator and switch assembly are protected from rain, dust, and ice, making it suitable for both indoor and outdoor gas trains.
What is the typical closing time for this safety valve?
As a safety shut-off valve, it is designed for rapid closure. While the motorized opening takes approximately 6 seconds, the normally closed spring-return mechanism trips in less than one second upon loss of power.
Can I use this valve with corrosive gases?
This specific model features Buna body o-rings and Trim Package 1, which are intended for general-purpose clean gases like natural gas or propane. For corrosive service, a different trim material may be required.
