Product Description
1/2" 68 degree K5.6 quick response upright fire sprinkler heads
1 Brief Introduction:
Glass bulb fire sprinklers are essential components of automatic sprinkler systems. They detect fire risks and control or extinguish fires by automatically spraying water. These are widely used in high-rise buildings, hotels, department stores, and warehouses. The operational environment temperature ranges from 4 ºC to 70 ºC.
2 Composition and Structure:
Constructed with a high-quality brass frame, splash deflector, glass ball, seals, and tight set screws.
3 Operating Principle:
Each sprinkler operates individually. When the ambient temperature reaches the calibrated thermal threshold, the thermal link breaks, allowing pressurized water to spray directly onto the heat source. In "Wet" pipe systems, water flow is limited to the area of high heat to minimize water damage.

Frequently Asked Questions (FAQ)
1. What is the working temperature range for these sprinklers?
The environment temperature for standard operation is between 4 ºC and 70 ºC.
2. What are the key materials used in the construction?
The sprinkler heads are made of a high-grade brass frame, glass bulb thermal link, splash deflector, and secure seals.
3. How does the glass bulb sprinkler operate during a fire?
When heat reaches the activation point (e.g., 68°C), the glass bulb bursts, allowing the water pressure to push out the seal and spray water onto the fire source.
4. Where are these fire sprinklers typically installed?
They are commonly used in commercial and industrial settings such as hotels, warehouses, department stores, and high-rise office buildings.
5. What mounting types are available?
We offer various types including Upright (SSU), Pendent (SSP), Sidewall (HSW/VSW), and Concealed configurations to suit different piping layouts.
6. What is the standard K-Factor for the 1/2" model?
The standard K-Factor for the 1/2" (DN15) model is 5.6, which corresponds to a flow coefficient of 80±4.
