Graco 17T452 Needle Valve Kit — Compatible Machines & Details

Compatible Machines

• Graco Continuous Mix Systems (e.g., 25M530 / 25M563) — needle valve used in precision flow control points
• Graco Hopper & Fluid Dispensing Units — fits models that incorporate a needle valve for accurate metering
• Other Graco industrial fluid systems that require precision needle valve assemblies

Product Description

The Graco 17T452 Kit, Needle Valve is a genuine OEM Graco needle valve assembly used to precisely control the flow of fluid or water within critical sections of Graco continuous mix and spraying systems. A needle valve — named for its tapered “needle” that seats into a matching orifice — allows fine adjustment of flow rate, making it ideal for dosing, mixing, and metering applications where small changes in flow can significantly influence output quality.

This replacement kit meets strict Graco specifications for durability, sealing, and responsiveness. Needle valves like this are often found on systems where fluid flow must be changed incrementally and reliably — for example at the interface between water dosing circuits and material mixing chambers. Regular inspection of the needle, seat, and sealing surfaces helps ensure smooth operation and reduces the risk of leaks or inconsistent flow.

Key Features

• Precise flow control for metering liquids with high accuracy
