Brass Inline Easy Read Flow Control Valve, Female 1/8-27 NPT Ports, Up to 3.00 GPM & 2000.00 PSI

Description & Features

Engineered for both hydraulic and pneumatic applications this inline valve features a durable brass construction that ensures long-lasting performance under demanding conditions. It supports operations at pressures up to 2000 PSI making it a robust choice for various industrial settings.

Designed with a 1/8-27 NPT port and a rated flow of up to 3.00 GPM this valve facilitates precise control in one direction while allowing free flow in the opposite direction. The color coding and numerical readout enable accurate repeatable settings enhancing system efficiency.

The metal knob and stem provide added durability and the valve's settings can be locked using a set screw. Components like the stainless steel retainer ball and spring along with a Delrin ball follower further contribute to the reliability and precision of this flow control valve.

The temperature range from -15F to 200F makes it versatile across various operating conditions. The use of Viton O-rings and Teflon washer seals ensures optimal sealing and performance accommodating a broad range of operational requirements.

How fine of an adjustment can you actually make on this thing? Like, is it touchy or can you dial it in pretty good?

Answer by: Customer Support on Sep 28, 2025, 5:38 PM

Pretty solid control, actually. The color coding and numbered readout let you nail down repeatable settings within a small fraction of a turn, and each full turn corresponds to one color band. That makes it a lot easier to get back to a known setting if you ever need to back off and come back. Once you've got it where you want it, there's a set screw to lock it down so it doesn't drift.
