Construction and operation

Needle Valve uses a tapered pin to gradually open a space for fine control of flow. 
The flow can be controlled and regulated with the use of a spindle. A needle valve 
has a relatively small orifice with a long, tapered seat, and a needleshaped plunger 
on the end of a screw, which exactly fits the seat.

 

Uses

Needle valves are usually used in flow metering applications, especially when a 
constant,calibrated, low flow rate must be maintained for some time, such as the 
idle fuel flow in
a carburetor.
