A needle valve for controlling fluid flow comprises a needle, a seat,and an actuator for moving the needle over a predetermined displacement between an open and closed position.
Needle valves are used to control flow into delicate gauges, which might be damaged by sudden surges of fluid under pressure.
Needle valves are also used in situations where the flow must be gradually brought to a halt and at other points where precise adjustments of flow are necessary or where a small flow rate is desired. They can be used as both on/off valves and for throttling service
Stainless steel needle valve
The Kp-lok FIG N.NVFF3131EA1027 needle valve is a straight-thru design with a Delrin seat, which provides bi-directional flow and the ability to "rod-out" the valve for cleaning.
These valves are specifically targeted for the oil and gas industry and are available only in 316 Stainless Steel per NACE MR-01-75.
