Spark 74℃ Fusible Alloy Sprinkler Head
Spark 74℃ Fusible Alloy Sprinkler Head
This is Spark’s 74℃ fusible alloy sprinkler head, a core fire extinguishing component of automatic sprinkler systems, widely used in fire systems of buildings such as hotels, shopping malls, and industrial plants. It senses ambient temperature through a fusible alloy element—when the temperature reaches 74℃, the alloy element melts, and the sprinkler head automatically sprays water to extinguish fire. Made of brass, it has a wide spray angle and large coverage area, combining corrosion resistance and fire extinguishing efficiency. It is a key equipment for automatic disposal of initial fires in buildings.

Frequently Asked Question
FAQ
What is a pressure relief valve?
+
-
The Forede pressure relief valve (PRV) is a mechanical device that releases gas or liquid from a system when the pressure exceeds a predetermined limit. PRVs are used to prevent over-pressurization, which can damage machinery or people
What is the purpose of pressure relief valve?
+
-
The PRV Pressure relief valve is a safety device that prevents a system from becoming dangerously pressurized by automatically releasing excess pressure. PRVs are used in many industrial settings, including power plants, chemical plants, and refineries, as well as in boilers, tanks, and pipelines.
How should i install the pressure relief valve?
+
-
The pressure relief valve came with flange end connection, please inform us the flange standard you need before placing the order to ensure the PRV valve could compatible with exist system.
What is the shipping methods?
+
-
It could be shipped by sea,by air or by express(EMS,UPS,DHL,TNT,FEDEX and ect). Please confirm with us before placing orders.

Our Main Product
Fire extinguishing equipment brand Spark recently released the 74℃ fusible alloy sprinkler head, featuring "precise temperature sensing + efficient spraying" as core highlights, becoming a core adaptation component of building automatic sprinkler systems.
This sprinkler head adopts a brass main body, combining corrosion resistance and structural stability, adapting to fire systems in multiple scenarios such as hotels and industrial plants; its core fusible alloy element accurately senses 74℃ ambient temperature, with rapid melting response, which can start spraying water in time at the initial stage of fire. The spray angle is designed as an umbrella shape, with a coverage radius of ≥3.0m, which can quickly control the spread of initial fire; the DN15 nominal diameter and external thread connection adapt to the pipeline layout of mainstream automatic sprinkler systems, with convenient installation.
The product is compatible with wet, dry and other types of automatic sprinkler systems, has passed the CCCF fire product certification, and complies with GB 5135.1 "Automatic Sprinkler Systems - Part 1: Sprinklers" standard. Currently, this sprinkler head is available on Spark’s self-built website, supporting customization of installation forms such as pendant and upright types, providing reliable automatic fire extinguishing protection for initial fire prevention in various buildings.
