A gas hob valve is a crucial component that controls the flow of gas to the burners on your stove. As a specialist in this manufacturing gas hob valves, here QUS will introduce some basic information to help you understand our work.
What Kind of Raw Material is Mainly Applied for Making Valves?
· Copper Alloy
Copper (or brass) is a very widely-used material in industrial production. Copper alloys are commonly used in applications requiring good corrosion resistance, such as valve body, valve core, and valve shaft.
· Aluminum Alloy
Aluminum alloys are now widely utilized in gas hob valves, particularly in components where weight reduction and corrosion resistance are prioritized. Aluminum has the same performance as copper alloy in reaching the CE standard of 40,000 numbers of operations. Replacing the valve body from copper to aluminum will not hugely affect the strength and durability of the valve, but can effectively reduce weight and costs.
Why are There So Many types of Gas Hob Valve in QUS Valve Catalog ?
In addition to classifying valves by material, the installation dimensions on your machine are also very important. The installation position of the gas pipes and the direction of the knob can determine the shape of the valve. You may send us the technical drawings of the valves that are suitable for your machine. The following functions divide valves into two categories:
· Valve with FFD
Flame Failure Device (FFD), or Flame Safety Device (FSD)—is a critical safety mechanism integrated into gas appliances like hobs and ovens. Its primary function is to automatically shut off the gas supply if the flame is extinguished unexpectedly, thereby preventing the accumulation of unburned gas, which could lead to fire or explosion hazards. This function is mainly controlled by solenoid valve, or we simply call it, a “magnet”.
- When the thermocouple top near the burner detects a drop in temperature,the other side of thermocouple which connect to the valve will give a signal to the “magnet”. According to the electromagnetic induction phenomenon, the solenoid valve will automatically shut off. Classic QUS valve model QS-L427 and QS-L416
· Valve without FFD
There are many basic valves without FFD. The gas will only start to flow as soon as the knob is spin to the maximum flow-rate. Such valve is more convenient to use.
Understanding the basic knowledge of gas hob valves is essential for ensuring safe and efficient use of gas appliances. From the types of valves and their working principles to the materials used in manufacturing, each component plays a vital role in controlling gas flow and maintaining safety. With proper knowledge and maintenance, gas hob valves can offer reliable performance and help prevent potential hazards in everyday cooking environments.
