Steel Inline Easy Read Needle Valve, Female 1/4-18 NPT Ports, Up to 10.00 GPM & 5000.00 PSI

At 5000 PSI, you're right at the rated maximum for non-shock service on this valve. As long as your system isn't throwing pressure spikes or surges, it holds up fine at that ceiling. The steel body and stainless steel needle are what make that rating possible on this particular model. Brass versions of this valve family are rated lower and meant for pneumatic or lighter hydraulic work, so the steel build here matters for your application.

This steel needle valve is designed for use in hydraulic systems. Brass valves, on the other hand, are better suited for pneumatic and lower-pressure hydraulic setups.

This steel needle valve is designed for precise flow control in hydraulic systems. It's good for applications where you need to adjust the flow, even with pressure on, and lock it down.

Built for on-the-fly adjustment, the easy-read knob lets you dial flow even under pressure, then lock the setting in place with the set screw. The color bands and numeric readout are there so you can come back to the same setting without guessing.

You can make adjustments while the system is under pressure with this valve. That's one of the practical advantages of the design. The color coding and numbered readouts help you dial in your setting accurately without guessing, and once you've got it where you want it, the set screw locks the position so it won't drift on you.
