Who is Victaulic?
Victaulic says its history dates to 1919, when the patent was filed for the coupling that later carried its name, and that its headquarters is in Easton, Pennsylvania. Its products include couplings, fittings, flow control valves, fire sprinklers and hydronic balancing equipment.
Victaulic sprinkler data sheets carry an approvals table for each model and advise checking the agency websites for the latest certification status. The listing is reviewed for the model, temperature rating and finish required, not for the series in general.
Victaulic sprinklers AZEIDK supplies
- The V4702 ESFR storage sprinkler: a quick-response pendent sprinkler with a K-factor of 16.8, 155°F (68°C) and 200°F (93°C) ratings and 175 psi maximum working pressure, for wet-pipe storage systems.
- FL-SR/ST K11.2 storage sprinklers: V3403 upright and V3407 pendent, standard response, for control mode density/area (CMDA) designs, with ratings from 135°F (57°C) to 286°F (141°C).
- V27 K5.6 sprinklers: V2703 standard-response upright, V2704 quick-response upright, V2707 standard-response pendent and V2708 quick-response pendent. The publication on our product page is marked as a discontinued submittal, so confirm current availability and the latest data sheet before specifying.

Where it fits in Saudi projects
ESFR and K11.2 storage sprinklers serve warehouses, distribution centers and logistics facilities, where storage height and commodity drive the protection method. ESFR sprinklers are suppression-mode storage sprinklers, while K11.2 storage sprinklers work in control mode.
V27 sprinklers suit offices, hospitals, factories and general buildings, while horizontal sidewall sprinklers serve rooms and corridors where ceiling piping is impractical, such as hotel rooms and apartments. The approved design under the Saudi Fire Protection Code (SBC 801) and Civil Defense requirements sets the sprinkler type and layout.
What to check before approval
- The design basis, NFPA 13 or FM Data Sheets, and a sprinkler with the matching cULus listing or FM approval.
- For storage: commodity, arrangement, storage and ceiling height, which decide whether ESFR or a density/area design applies and the pressure needed.
- The temperature rating against the highest expected ceiling temperature, especially under metal roofs in summer.
- The K-factor and minimum operating pressure against the hydraulic calculations.
- Escutcheons for recessed installation, since the approval is tied to the escutcheon named in the data sheet.
- The latest data sheet for each model, as older submittals may be superseded or models discontinued.

FAQ
Who is Victaulic?
Victaulic is a US company based in Easton, Pennsylvania, whose history dates to 1919, when the patent was filed for the mechanical coupling that carries its name. It makes couplings, fittings, valves and fire sprinklers. AZEIDK supplies its FireLock sprinklers for storage and general buildings as shown on our product pages.
Is the V4702 ESFR sprinkler right for my warehouse?
That depends on the commodity, storage arrangement, storage and ceiling height, roof slope and design standard. Victaulic’s data sheet describes the V4702 as a quick-response K16.8 storage sprinkler and refers to NFPA 13 and FM Data Sheets in its application tables. The designer checks the listing limits for the actual case before selecting it.
Are Victaulic sprinklers UL listed and FM approved?
It varies by model. The V4702 data sheet lists cULus and FM, data sheet 44.51 gives both for the K11.2 storage sprinklers, and sidewall approvals vary by model, arrangement and finish. Check the approvals table in the latest data sheet for the model and confirm it on the agency websites.
How does ESFR differ from the K11.2 storage sprinklers?
ESFR is a suppression-mode storage sprinkler: its fast-response element opens it early and its large K-factor delivers a heavy discharge. The K11.2 sprinklers are standard response and work in control mode under a density/area design. Storage height, ceiling height and commodity decide which suits the project.
When are horizontal sidewall sprinklers used?
They are used where ceiling piping is impractical. They mount on the wall and throw water across the room, as in hotel rooms, apartments and corridors. AZEIDK offers them with K-factors from 2.8 to 8.0, and the design sets their coverage and spacing according to the listing of the chosen model.
