Where is a 2.5" Fire Hose Valve commonly found?

2-1/2" fire hose valves are used as a fire department outlet connection commonly found in stairwell landings of multi-story buildings or as part of a test header assembly on the outside of your building. Additionally, fire hose valves are used with pin rack fire hose units inside of a cabinet, which is why fire hose valves are often called a fire hose cabinet valve. Most internal fire fighting hose applications - whether from fire fighters bringing hose or stationary pin rack units - use 1.5" fire hose and, as such, this valve will commonly pair with a 2.5" to 1.5" hose valve reducer.

Fire hose valves are part of the standpipe system. When a fire department connects to a fire department connection (FDC) to charge an automatic sprinkler system or a standpipe system, the fire hose valve is the outlet where firefighters can connect their hose on specific floors. If the fire hose valve is part of a pin rack unit, the concept remains the same - an access point for water to fight the fire - but the pin rack unit provides the hose.

Is this 2.5" fire hose valve UL and FM approved?

Yes, all fire hose valves on are Underwriters Laboratory (UL) and Factory Mutual (FM) approved. While this product is imported, it meets the rigorous standards set forth by both UL and FM. It is also C UL US, which means it is also approved for the Canadian market.
