VK580消防噴頭,直立式灑水噴頭viking:Viking標準響應直立噴水器VK580是一個熱敏玻璃球噴霧器,可提供各種溫度額定值,以滿足設計要求。 在具有16.8標稱K系數的情況下,與具有較小K系數的噴灑器相比,噴灑器在較低壓力下提供更大的流量。維景消防噴頭,VK580型消防噴頭,直立式消防噴頭VK580,viking消防灑水噴頭TECHNICAL DATA Speci? cations: Available since 2004. Maximum Working Pressure: 175 psi (12 bar). Factory tested hydrostatically to 500 psi (34.5 bar). Thread size: 3/4” (20 mm) NPT Nominal K-Factor: 16.8 U.S. (242 metric*) *Metric K-factor measurement shown is when pressure is measured in Bar. When pressure is measured in kPa, divide the metric K-factor shown by 10.0. Glass-bulb fluid temperature rated to -65 °F (-55 °C) Overall Length: 2-7/16” (62 mm)
該特征允許減少用于液壓計算的噴灑器系統的管尺寸,并且提供允許增加占用的危險分類所需的較高密度。 Viking標準反應噴灑器VK580經過**的高堆存儲防火測試,并經過cULus認證和FM認證,用于保護高堆存儲。
