Needle valves are divided into two main types: the simplified type and the precision type.
The simplified type has a needle valve knob made integral, and the needle rotates to control flow.
Meanwhile, the precision type has a needle and knob made separately, and the needle moves directly without rotation. The precision type excels in both ease of flow setting and stability. Select an appropriate type in terms of price and accuracy according to the intended usage.

The Model 2203 (flow controller) is a constant flow valve that maintains a constant flow when the secondary pressure changes.
Model 2204 (flow controller) maintains a constant flow at the outlet side when the primary flow changes.
The Model 2412 precision needle valve is used for very small flow, while the Model 2412D is used for a wide range of uses as a largecapacity type.
The Models 2400 and 2400D are simplified versions of the Models 2412 and 2412D.
The bellows seal Model 2450 is a low leakage valve that is suitable for use in a vacuum line. The Model 2412M is a precision needle valve equipped with a dial gauge.

Advise us of the above, and we can offer the best type irrespective of the needle number.
Of course, we can also manufacture a needle valve according to the specified needle number
