VK514 - ESFR Pendent Sprinkler (K28)

Viking's VK514 Specific Application ESFR Storage Pendent Sprinkler is UL Listed to provide ceiling-only protection for stored commodities up to 43 ft (13,1 m) in warehouses with ceiling heights of 48 ft (14,6 m). Specifically listed for 6 ft (1,8 m) aisle widths, the VK514 protects class I-IV commodities and cartoned unexpanded plastics stored in single- or double-row racks, with no in-rack sprinklers required.

With a larger K-factor of 28 (404), lower pressure requirement of 35 psi (2,4 bar), and flow rate of 166 gpm (628 lpm), the VK514 reduces water demand for the sprinkler system overall, and in some applications may allow for smaller pipe sizes and can eliminate the need for a fire pump.

The Model VK514 sprinkler is offered in ordinary and intermediate temperature ratings of 165°F (74°C) and 205°F (96°C), and has a 1 inch NPT or 25 mm BSP thread size.
