Accessories 338 Series Flow Control Valves, 1/8" to 3/4" Ports

Brand: Parker ORIGA Corporation

338 Series needle valves bi-directionally meter the flow of air through the valve.

This series features a fine tapered needle providing precise flow of air in both directions. 

Numerical micrometer position markings are stamped on the perimeter of the adjustment knob which provide a visual indication of the setting. 

Once the desired flow is selected, a set screw can be tightened to maintain the setting.

These valves are available with NPTF ports in 1/8", 1/4", 3/8" 1/2" and 3/4" sizes. 

This series is recommended for pneumatic service.
