17W643 kit operates within a relief range of 150–800 psi, accommodating diverse process requirements. Flow capacities meet up to 10 gallons per minute at nominal settings, reducing backpressure effects. Component tolerances adhere to ±0.001 inch for critical mating surfaces, ensuring leak-free performance. Operating temperature spans from -20°F to 200°F, allowing compatibility with solvent-based coatings, waterborne materials, and light oils. Repeatability tests confirm that relief thresholds deviate less than 5% after 100,000 cycles.
Critical parts are crafted from 304 stainless steel and treated with passivation to resist oxidation. Sealing elements incorporate high-grade fluorocarbon elastomers, providing chemical resilience and dimensional stability. Springs use tempered alloy steel to maintain consistent force over extended cycles. All fastening hardware is zinc-plated or stainless to prevent galvanic corrosion. This material suite combines longevity with ease of cleaning, simplifying decontamination when switching between abrasive or exotic fluid media.
High-demand sectors such as automotive refinishing, marine coatings, and architectural spraying rely on robust pressure relief solutions. Graco 17W643 excels in high-viscosity fluid transfer and maintains stable output during peak production runs. In maintenance operations, installers integrate the kit into fixed and portable units for quick service downtime. Its versatility extends to chemical dosing systems and specialty finishing equipment, where precise control over backpressure is crucial to achieving consistent layer thickness.
Compliance with ANSI and ISO pressure vessel directives ensures that the kit meets stringent safety benchmarks. Relief performance has been certified under rigorous laboratory testing environments, verifying responsiveness to transient pressure spikes. Installation procedures align with NFPA guidelines for sprayer systems, and color-coded components facilitate rapid identification during audits. Safety covers and backflow prevention devices complement the relief assembly to protect personnel and adjacent equipment.
