Crown Engineering B400F Valve
For service contractors and facility managers, the Crown Engineering B400F valve is the industry standard for securing fuel lines against thermal runaway. This Firomatic 1 inch NPT valve, also identified by part number 12113, is a globe-style fusible safety valve engineered for massive reliability in both residential and high-capacity commercial oil heating systems. Unlike standard shut-offs, this fusible in-line valve features a handwheel with a built-in fusible link that melts at 165°F, triggering an immediate positive shut-off to isolate the fuel supply. Built from heavy-duty brass, the B400F fusible valve utilizes a high-grade Viton equivalent double-seal washer system, ensuring compatibility with No. 2 fuel oil, kerosene, and biodiesel blends up to B20. The 1" female NPT connections provide a robust interface for high-flow piping, while the embossed flow direction arrow simplifies field installation. Meeting UL/ULC 842 standards, this fire safety valve is an essential component for NFPA 31 and CSA B139 compliance on the job site.
Key Benefits- Automatic Thermal Response: The 165°F fusible handwheel ensures the Firomatic B400F globe valve closes permanently during a fire event.
- High-Flow Capacity: Dual 1" NPT female ports provide low pressure drop, making it ideal for larger commercial burner supply lines.
- Fuel Versatility: Specialized Viton internal seals are rated for standard fuel oils and modern renewable biodiesel blends.
- Robust Compliance: UL/ULC 842 listed for use in the United States and Canada, ensuring adherence to local safety codes.
- Field-Proven Durability: Heavy-duty brass construction resists corrosion and withstands the vibration of industrial boiler rooms.
Is the B400F valve compatible with biodiesel?
Yes, the internal seal system uses Viton equivalent materials specifically chosen for resilience against biodiesel blends up to 20% (B20), as well as kerosene and No. 2 fuel oil.
What happens if the fusible link melts?
Once the ambient temperature reaches 165°F, the fusible link in the handle melts, allowing the spring-loaded stem to snap shut. In such cases, the entire handle or valve assembly must be replaced after the system is cleared for service.
Can this valve be installed in any orientation?
While globe valves are versatile, it is critical to follow the arrow embossed on the brass body to ensure the correct direction of oil flow and proper seating of the internal seal.
