UL provides testing, certification and Standards development for all types of valves used in fire suppression systems. Types of valves certified by UL include alarm valves used to summon the fire department, check valves used to prevent water from being pumped back into the water main and deluge valves used to discharge water to open sprinklers.
Valves are subjected to performance tests such as leakage, hydrostatic pressure, friction loss, operation, cycling and the long-term effects of aging.
Operational tests can be conducted at UL’s hydraulics laboratory in Northbrook, Ill., at the manufacturer’s facility, or at another hydraulics laboratory selected by the manufacturer.
We test to UL Standards, and the requirements for the installation and use of these valves are included in the National Fire Protection Association (NFPA) installation standards for valves used in fire suppression systems: NFPA 11, 13, 14, 15, 16, 20, 22 and 24. UL is also authorized to certify valves for fire suppression systems to Canadian standards.
Wet and dry alarm valves compliant with EN 12259-2 and EN 12259-3, respectively, may use the CE Mark for the Construction Products Regulation (CPR), which applies to European products incorporated into permanent structures.
