Brass Inline Easy Read Needle Valve, Female 1/4-18 NPT Ports, Up to 10.00 GPM & 2000.00 PSI

Description & Features

Expertly designed for precise control in pneumatic and low pressure hydraulic systems, this needle valve features color coding and numerical readout for accurate settings. With a maximum operating pressure of 2000 PSI and a rated flow of up to 10.00 GPM, this valve offers reliable performance in demanding conditions.

Constructed from durable brass, the body ensures longevity and reliability. The vitonreg; O-ring and teflonreg; washer seal provide a secure and leakage-free experience, while the aluminum knob and metal stem contribute to its robustness. The valve's compact size with 1/4-18 NPT ports makes it suitable for various industrial applications.

Flow adjustments can be made under pressure, and settings can be locked with a set screw for added security. The stainless steel needle in the valve ensures smooth and precise flow control. Suitable for controlled flow in both directions, this needle valve is a versatile component for efficient system management.

Question by: Denise P on Apr 10, 2025, 1:50 PM

runs up to 2000 PSI on this thing, but we're using it on a lower-pressure pneumatic line most of the time. brass gonna hold up alright for that kind of duty?

Answer by: Customer Support on Apr 12, 2025, 6:10 AM

Brass is actually the right call for pneumatic systems and lower-pressure hydraulic work. The 2000 PSI rating covers your higher-end use cases, but brass valves in this lineup are specifically noted for pneumatic service and lighter hydraulic applications. The Viton o-ring and Teflon washer seal hold up well across a wide temperature range too, from -15°F all the way up to 400°F, so everyday pneumatic duty is well within what this valve handles comfortably.

got a little hydraulic circuit i need to tame down, will this valve let me dial the flow while the line is still pressurized?

Answer by: Customer Support on Mar 13, 2026, 2:28 PM

Adjustments can be made under pressure on this easy read needle valve, and it is meant for controlled flow in both directions. Once you get the setting where you want it, the set screw lets you lock it in.

Question by: Gary M on Feb 17, 2026, 5:47 PM

does this valve work for both air and hydraulic lines, or just one or the other?

Answer by: Customer Support on Feb 18, 2026, 7:48 PM

Brass construction makes it a solid fit for pneumatic systems and lower pressure hydraulic applications. The 2000 PSI max and 10 GPM flow rating cover a good range of those uses. Just keep in mind that for higher pressure hydraulic work, steel body valves are the better call. For air lines and moderate hydraulic setups, this one handles it fine.

Question by: Ronnie B on May 14, 2025, 10:37 AM

How tight can I lock down the flow on this thing? I need it nearly shut off for a very slow feed.

Answer by: Customer Support on May 15, 2025, 12:07 PM

This needle valve allows for accurate adjustments within a small fraction of a turn, or one full turn per color marking, so you should be able to dial in a very precise flow. Plus, you can lock your setting in place with the set screw.
