A finely threaded, needle-shaped plunger allows you to precisely regulate airflow by gradually tuning the size of the valve's inlet port. Needle valves can reduce flow in both directions.
These valves withstand moisture and chemicals better than other needle valves. They are made from corrosion-resistant materials and can be used in various applications. Turn the adjustment knob to set the flow rate. The color-coded bands provide a visual cue for the set point and allow you to adjust it consistently.
Pressure Gauge & Instrumentation
Regulate line flow and minimize pulsation from pressure change with these valves. They are commonly used in test instrument setups.
Oil, Water, & Gas
Designed for environments where oil, water, and gas particulates might end up in the air lines, these valves are often used to throttle devices on lines where rapid and excessively pulsating pressures would affect gauge performance or mechanism.
