Medium Pressure Needle Valve

Needle valve is used to accurately control flow rates of clean gasses or liquids. Gradual adjustments of the stem and plunger enable smooth flow control. These valves generally have low flow rates and a relatively significant pressure drop from the inlet to the outlet. Standard port sizes for needle valves range from 1/8” to 2” (2 to 12 mm). The most common application of a needle valve is to control gas flow, such as propane in a tank.
