Parker Hydraulic Needle Valves

We offer Parker hydraulic needle valves for speed controls on hydraulic and pneumatic systems where a reverse flow check is not needed…

They provide excellent control and a reliable shutoff in a very small envelope. A two-step needle 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 also provide standard throttling adjustments.
