Product Description

Victaulic V38 Standard Response Concealed Pendent Fire Sprinkler delivers decorative, competitively-priced defense against fire in ordinary hazard commercial occupancies such as universities, auditoriums, churches, and parking garages. Using a heat-activated 5mm glass bulb, this automatic fire sprinkler opens when ambient temperatures reach 155F (68C), drenching the area surrounding a fire to keep it in its place of origin.

Low-profile cover plates mount flush to the ceiling and are available with a white or chrome-plated finish, as well as a flat-black or custom finish by special order. When temperatures near the ceiling reach 135F (57C), the soldered cover plate detaches, exposing the head of the Victaulic V38 concealed pendent fire sprinkler, which activates when temperatures reach 155F (68C).

The Victaulic Model V38 has a 5.6 K-Factor and installs with 1/2" (12.7 mm) National Pipe Thread (NPT), used in fire sprinkler systems throughout the United States. This Standard Response Fire Sprinkler features a die-cast brass frame, bronze deflector, cold-rolled steel cup, and a stainless steel spring. Pendent sprinklers direct the water stream downward against the deflector to distribute water in a hemispherical spray pattern. The frame is cast with a hex-shap.

This 155F (68C) temperature rating strikes a balance between a fire sprinkler that activates too soon, causing accidental discharge, and too late. 155F (68C) Standard Response Fire Sprinklers can be installed to wet and dry pipe fire sprinkler systems, and are preferred for use in one and two-family dwellings, apartments, duplexes, and boarding houses when a low profile is desirable. The Victaulic Model V38 is also a suitable choice for installation in many college dormitories, condominiums, and nursing homes.

With a maximum working pressure of 175 PSI (12.1 BAR), this pendent sprinkler hangs from above-ceiling piping behind a decorative cover plate and may be installed and used in accordance with NFPA 13 and local fire code. Each Model V38 sprinkler is made by Victaulic, a global manufacturer with more than a half-century in the fire protection industry.

This product is UL-listed, and appropriate for use in fire protection systems when accepted by the authority having jurisdiction. In accordance with NFPA 13, a higher temperature rating may be required when installing a standard response fire sprinkler in or near heat sources, unventilated spaces, uncovered steam mains, or uninsulated rooftops. Concealed pendent sprinklers should no
