Stockton Valve Products distributes a full line of Needle Valves, including Gauge Valves and more.

needle valve is a type of valve having a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, although it is generally only capable of relatively low flow rates. Needle valves are usually used in flow metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time.
