What is the primary function of a control valve in a torch?

The primary function of a control valve in a torch is to regulate gas flow. This component allows the user to adjust the amount of gas that flows from the supply source to the torch. Proper regulation is crucial for achieving the desired flame characteristics and intensity needed for various tasks such as welding, cutting, or heating materials.

By controlling the gas flow, the user can manage the flame size and temperature, ensuring that it is appropriate for the specific application at hand. This regulation is essential for both safety and effectiveness in handling heating or cutting tasks.

While igniting the flame is an important step in using a torch, it is not the primary function of the control valve; rather, it typically involves a lighter or ignition system. Connecting hoses is a basic necessity but does not pertain specifically to the function of the control valve itself. Monitoring temperature is usually done through separate equipment, not through the control valve, which focuses specifically on gas flow management.
