Metal Needle Valves - F28223 Series

Metal Needle Valves are an adjustable method of flow control. Internally, the pin and body create an adjustable orifice that restricts flow. Useful for instances when the exact flow rate hasn't been determined or to compensate for flow variation in other parts of the system. Very fine threads ensure adjustment accuracy. A nylon insert in the threads increases the friction and reduces the likelihood of vibrations causing a change in the flow rate.
