Question: 1 / 400

What type of valve allows for accurate flow control?

Ball Valve

Check Valve

Gate Valve

Needle Valve

A needle valve is designed for precise flow regulation, making it ideal for applications requiring accurate adjustments in fluid flow. The fine-threaded stem of a needle valve allows for nearly infinite control over the flow rate, enabling the operator to make minute changes. This capability is particularly useful in processes where precise measurements are crucial, such as in laboratory settings, fuel injection systems, and hydraulic applications.

In contrast, a ball valve provides quick on/off control and does not allow for fine adjustment of flow. Gate valves are primarily used to start or stop the flow with minimal resistance but are not suitable for throttling applications. Check valves are designed to prevent backflow and do not offer control over flow rates at all. Thus, the needle valve stands out as the best option for achieving accurate flow control.
