Parker Needle Valves
In-Line General Purpose Needle Valve – N Series

The N series of hydraulic flow control, in-line needle valves meters flow in both directions or provides a reliable shut off. This needle valve flow control is used in air and oil applications and has standard and fine metering options.

Parker's N series valve is a two-step needle that allows fine adjustment at low flow by using the first three turns of the adjusting knob. The next three turns open the valve to full flow and provides standard throttling adjustments.
