Product Pormation

V2704: Quick-response upspray nozzle, nominal K coefficient 5.6 (corresponding to 8.1 in the International System of Units), threaded interface 1/2-inch NPT. The top of the frame is conical, which can reduce the interference of obstacles on the water flow and is suitable for places with limited space under the ceiling.

V2708: Quick-response downspray nozzle, nominal K coefficient 5.6, threaded interface 1/2-inch NPT, supports embedded mounting (requires V27 recessed escutcheon). The recessed design supports embedded installation, flush with the ceiling, which is both aesthetically pleasing and reduces the risk of mechanical damage.

The frame is made of brass, the splash pan is made of copper, the spring gasket is made of PTFE-coated beryllium-nickel alloy, and the positioning spring is made of stainless steel

Temperature rating: All are available at 68 ° C (155°F), suitable for conventional fire risk environments.

Product Features

1. Quick response and efficient fire control

3mm glass bulb: Response time index (RTI) ≤50 (m·s)⁰·⁵, 30%-50% faster than standard nozzles. Quickly activates in early fire to control spread.

Hemispherical water mist model: Optimized splash pan design for large-area uniform spray, wide coverage, compliant with NFPA 13 standards.

2. Excellent anti-corrosion performance

Multi-layer protection: Brass frame, copper splash pan, PTFE-coated beryllium-nickel alloy spring gasket, stainless steel positioning spring.

Certified coatings: UL-listed & FM-certified white/black polyester paint, VC-250 coating; suitable for coastal, chemical plant and other corrosive environments.

3. Structural design and installation convenience

Top-spray (V2704): Conical frame reduces obstacle interference, for spaces with limited ceiling clearance.

Downspray (V2708): Recessed design for flush ceiling installation (with V27 recessed escutcheon), aesthetic and anti-mechanical damage.

Dedicated wrench installation: Use V27/V27-2 wrench to ensure torque compliance, avoid glass bulb breakage from over-tightening.
