Product Description
The Graco 104632 Valve, Piloted is a robust 3-way control valve engineered for precise fluid regulation in high-pressure, industrial spray systems. Its pilot-actuated spool mechanism enables rapid response to changing load conditions, delivering reliable performance in demanding environments.
Key Features
- 3-way pilot-operated spool: Enables pump unload, recirculation or bypass control with minimal delay.
- Durable construction: Machined body with hardened internals withstands high-cycle, high-pressure use.
- Optimised flow paths: Minimises pressure drop and helps maintain stable fluid delivery.
- Flexible integration: Designed for manifold or block-mounted installation in spray systems.
- High-end performance: Tailored for continuous production use, including pigment-laden or solvent-rich fluids.

Applications
The Graco 104632 Valve is ideal for industrial finishing lines, mobile spray rigs and OEM fluid-handling systems where fast switch-over, accurate pressure control and consistent fluid delivery are required. It supports complex circuits for coating application, fluid transfer and high-flow pumping systems.
Performance Advantages
- Enables tight control of pump unload cycles and fluid recirculation.
- Reduces system energy loss through optimised spool design and low leak paths.
- Improves finish consistency by stabilising flow and pressure under varying conditions.
- Minimises maintenance downtime thanks to durable materials and service-design spool cartridge.
- Supports high-build coatings and demanding fluid chemistries without sacrificing reliability.
Maintenance Tips
During service, ensure the pilot line remains free of debris, inspect the spool and seals for wear, and verify the valve cycles fully open and close. Replace worn components promptly to maintain trigger responsiveness and system integrity.
