Needle Valves

Needle valves are a type of valve that is used to precisely control the flow of fluids and gases. They are typically used in applications where a high degree of accuracy is required, such as in medical devices, chemical processing equipment, and analytical instrumentation.

Needle valves get their name from the tapered, needle-shaped plunger that is used to control the flow. The plunger is inserted into a seat, which creates a seal to prevent leakage. The plunger is typically threaded, so that it can be adjusted to open and close the valve.

Needle valves are very precise because they can be adjusted in very small increments. This is because the needle-shaped plunger provides a very gradual increase or decrease in the size of the opening.

Needle valves are typically made of brass, stainless steel, or other corrosion-resistant materials. They are also available in a variety of sizes and pressure ratings.
