Maxon Boiler Relief & Safety Valves: Industrial-Grade Protection You Can Count On
When boiler systems are at stake, the margin for error is zero. Maxon — now a Honeywell company — has been setting the benchmark for combustion safety equipment since 1926, and their presence in the Boiler Relief & Safety Valves category reflects decades of hard-earned engineering credibility. Maxon has been an industry leader since 1926, renowned for combustion equipment and widely recognized "MAXON Valves" that set the standard for safety and reliability in industrial gas service.
Why Maxon Safety Valves Stand Apart
In the world of boiler safety, speed and reliability during a fault condition are everything. Maxon electrically actuated safety valves shut off gas or oil lines in less than one second, and all valves come equipped with Maxon's long-lasting metal-to-metal seating. This design philosophy — prioritizing fast, definitive closure — means that in the event of a power interruption or safety circuit signal, fuel is cut off almost instantaneously, limiting the risk of dangerous pressure buildups or uncontrolled combustion events.
Maxon shut-off valve operating pressures and valve Cv's are among the highest available in the industry, meaning you can move more fuel in smaller-size valves than competitive products. This combination of high flow capacity and compact footprint makes Maxon valves particularly well-suited for space-constrained boiler rooms and retrofit applications where line sizes are fixed.
Notable Product Series
Maxon offers several valve series relevant to boiler safety applications. The 5000 Series provides application flexibility with 3/4" through 6" line sizes and line pressures up to 125 psig. A variety of optional body materials and connections provide reliable operation even for highly corrosive fuels, with cast iron, carbon steel, low-temperature carbon steel, and stainless steel body assemblies available — and oxygen compatibility also offered. For pneumatically actuated applications, the Series 8000 features a powerful closing spring and a large, top-mounted 360-degree open/shut visual position indicator.
Actuator enclosures on Maxon valves meet IP65 and NEMA 1, 3, 3S, 4, and 12 ratings, while straight-through flow swinging gate valve bodies minimize line pressure drops and provide positive visual indication of valve body position with a large two-color open/shut indicator.
Certifications & Quality Standards
Maxon is a worldwide manufacturer of industrial combustion equipment and shut-off valves with manufacturing facilities in the United States and Europe, and has earned the distinction of being the first industrial burner manufacturer to receive ISO 9001 Certification. For hazardous-location boiler environments, Maxon "NI" valves are FM approved for hazardous locations including Class I, Division 2, Groups A, B, C, and D.
