Valves are designed to do one or more things in a system. Some valves are designed to quickly and easily shut the flow off or turn the flow on. While these valves also offer some control of the volume of the flow, they are not precise.
When it comes to precision control of the flow of gases, liquids, or other types of media through a system, a brass needle valve is an ideal option. There are several reasons why this type of valve is popular in both larger applications and as miniature needle valves.
Fine Tune the Flow
The designs of the needle valve allow for fine control over the flow of the gas through the valve body. The actual valve is a needle-shape and fits perfectly into the V-shaped seat and seal. As the needle is retracted, the exact amount of gas can pass through the valve, with just partial turns refining the volume with ease.
Durable Body and Control Button or Knob
The choice of a brass needle valve means a durable body, as well as a choice in knob to control the flow. This valve is not typically panel mounted, so the choice of brass as the body material makes the valve resistant to damage and impact. These valves can be designed to swivel, making it easy to use with tubing and other types of flexible systems.
Corrosion Resistance
A brass needle valve offers excellent corrosion resistance. This is of particular importance when the valve is used in areas where there may be moisture or high humidity present.
Pressure and Temperature Range
Typically, needle valves are designed for standard pressure systems. They can also be custom designed for high or low pressure to meet the needs of a given application.
