Maxon 150SMM11AA11BA1A0 Gas Valve

The Maxon 150SMM11AA11BA1A0 Gas Valve is an industrial safety shut-off valve engineered for critical fuel line applications in boilers, kilns, and thermal oxidation systems. As a 1.5-inch ANSI threaded gas valve featuring a cast iron body and Buna-N O-rings, this unit is built to withstand rigorous industrial environments. This 2-way normally closed model utilizes a manual reset mechanism, requiring a technician to be physically present to engage the valve after a safety trip, ensuring maximum operational oversight. The integrated 115Vac 60Hz solenoid provides reliable holding power, while the internal trim package 1 and VOS1/VCS1 limit switches allow for precise remote position monitoring. Designed with a NEMA 4 enclosure rating, the actuator assembly is protected against dust and water ingress, making it suitable for standard and washdown-heavy environments. This Maxon 808 Series valve ensures a standard port flow capacity with a technical Cv of 53, providing optimal throughput for general-purpose gas service without excessive pressure drop.

Key Benefits

• Metal-to-Metal Seating: Features Maxon’s signature micro-lapped seating surfaces for consistent Class VI shut-off and long-term reliability in high-cycle applications.
• Manual Reset Security: The manual-reset actuator prevents unintended automatic restarts, a critical safety feature for large-scale combustion systems.
• Field Rotatable Top: The actuator assembly can be rotated in 90-degree increments to accommodate tight piping configurations and diverse mounting requirements.
• Standardized Monitoring: Equipped with VOS1 (Valve Open Switch) and VCS1 (Valve Closed Switch) for seamless integration into burner management systems (BMS).
• Rugged Construction: Cast iron body paired with Buna-N seals ensures compatibility with natural gas, propane, and other clean fuel gases.

Common Questions What is the maximum operating pressure (MOPD) for this Maxon valve? The Maxon 150SMM11AA11BA1A0 is typically rated for a maximum operating pressure differential (MOPD) of up to 70 psig, depending on the specific solenoid and trim configuration. Can this valve be used for outdoor installations? Yes, the NEMA 4 enclosure rating ensures that the internal electrical components are protected against windblown dust, rain, and hose-directed water. What is the flow coefficient (Cv) for the 1.5" standard port model? This 1 1/2" ANSI threaded valve features a Cv of 53, which is the industry standard for Maxon 808 series valves with a standard port flow capacity.
