Graco 104636 Valve, P-B 3-Way 10-32 – Precision Fluid-Handling 3-Way Valve
Compatible Machines
- Graco plural-component spray systems
- Graco high-flow fluid‐handling and metering modules
- Graco industrial finishing rigs with 3-way valve manifolds
- Graco mobile dispensing and coating stations using ⅛-in & 10-32 pilot connections
Product Description
The Graco 104636 Valve, P-B 3-Way 10-32 is a compact but rugged 3-way valve engineered for precision control of fluid flow in advanced industrial and finishing systems. Its “P-B” (Pilot to Base) style design allows versatile integration into complex manifolds, enabling effective switching between pump, bypass and block flow paths with minimal transition time.
Key Features
- Three-way fluid path: permits flow routing between pump, bypass and block positions with ease.
- 10-32 pilot connection interface: integrates seamlessly with control manifolds and low-volume signal lines.
- Compact form factor: ideal for tight installations within spray modules, metering units or pump skid assemblies.
- Durable construction: built to withstand high-cycle industrial use in fluid-handling and coating applications.
- Precise actuation: minimal internal leak paths and accurate switching help maintain pressure stability and system reliability.

Applications
This valve is used in high-performance finishing and fluid-handling equipment from Graco where compact geometry, accurate fluid switching, and robust industrial duty are required. Typical applications include plural-component spray rigs, automated metering systems, and coating stations needing reliable bypass or pump isolation flow paths.
Performance Advantages
- Enables rapid and clean switching between fluid flow paths, reducing system lag.
- Helps maintain system pressure and flow stability by using precision internal passage design.
- Compact size allows integration in tight assemblies and helps lower manifold footprint.
- Improves reliability and serviceability in demanding finishing environments.
- Supports advanced equipment designs by offering pilot-based actuation for seamless system control.
Maintenance Tips
During routine maintenance, verify that the pilot connection (10-32) is clean and free of debris, check for internal leakage between flow paths, and ensure that the valve switches fully between positions. Replace the valve if flow paths do not shift cleanly, if leaks develop, or if mounting tolerances are compromised.
Frequently Asked Questions
The “10-32” refers to the thread size of the pilot control connection, indicating a fine-thread signal interface used for controlling the main valve actuation in a compact package.
Yes — the 104636 is designed for robust industrial fluid-handling use, including spray and finishing systems. Confirm the specific fluid port ratings in your system specs.
Ensure your system requires a 3-way pilot-actuated valve with a 10-32 pilot thread and verify compatibility with Graco equipment. Also check flow rating and port size to ensure proper fit.
Replace the valve if you notice difficulty switching between flow paths, internal leaks, pilot line loss of control, or mounting issues. Early replacement prevents downstream equipment damage.
