This high-grade component set seamlessly integrates with select Graco pumps and valves, delivering consistent performance for heavy-duty spraying tasks. Ideal for use with cutting-edge airless sprayer systems, it supports a wide range of professional coatings while maintaining optimal flow rates and minimizing downtime. Manufactured with rugged stainless steel components, it withstands abrasive materials and frequent cycling for years of reliable operation.
Each kit includes precision-engineered stop balls and mounting pins that simplify replacement and maintenance, reducing downtime in high-pressure environments. Designed for compatibility with a variety of Graco and OEM assemblies, the 17K490 Kit delivers consistent performance even under extreme pressures. Routine inspections and cleaning of the ball valve assembly help maintain high-pressure filtration integrity, ensuring your application remains free of blockages and continues to produce smooth, professional-grade finishes.
Graco 17K490 Kit Stop Ball W/ Pins redefines reliability for fluid control tasks by combining rugged construction with pinpoint accuracy. Ideal for contractors and maintenance professionals, this assembly safeguards valve operation and minimizes downtime through superior material selection and exacting tolerances. Users will notice how the sintered sealing surfaces maintain integrity under dynamic loads, while the pins guarantee consistent alignment and engagement in high-pressure circuits.
Equipment operators concerned with uptime and maintenance overhead can rely on graco spray rigs to deliver consistent results even in harsh environments where corrosive agents or abrasive particulates jeopardize less robust assemblies. Rapid pressure adjustments and precise feed control in mobile units benefit greatly from components built to last. Field studies cite fewer operational faults when cascade valve sequences employ high-precision stop ball kits calibrated for consistent breakpoints.
Construction of each component involves aerospace-grade stainless alloys that resist galling and corrosion. Dimensions are held to tight tolerances—typically ±0.005 inches—to ensure a leak-free pivot point. Surface finishes are achieved via precision polishing, reducing friction coefficients and extending service life. Corrosion resistance is enhanced by electroless nickel plating on pin shanks to complement stainless steel resilience, extending part longevity. Stress-relieved pins are honed to exact diameters to align smoothly with mating housing bores, removing any slack that could undermine sealing performance.
Compatibility with diverse valve architectures makes this stop ball kit a go-to choice for applications ranging from protective coatings to industrial chemical delivery. Integration requires minimal modification: pin bores match ANSI and ISO standards, so neither complex machining nor additional adaptors are necessary. System builders will appreciate how the stop ball slides seamlessly into existing assemblies without altering manifold geometries.
Routine maintenance benefits from the user-friendly design of the stop ball kit. Disassembly is straightforward thanks to captive retaining pins that prevent accidental loss during service. Technicians can inspect sealing surfaces and pins within minutes, without specialized tools or extensive downtime. Periodic lubrication is sufficient to maintain smooth operation, and replacement intervals are extended compared to legacy components.
Valves fitted with this kit endure cyclic pressure spikes up to 3,500 psi and temperature extremes from -40°F to 450°F. Shock absorption is intrinsic due to the slight radial clearance designed into the assembly, providing resilience against hydraulic pulses. Flow characteristics remain stable across the rated range, with negligible variation in Cv values throughout the component’s lifespan.
Follow these professional tips for optimal results: begin with a cleaned cavity, verify pin alignment, and torque fasteners to manufacturer specifications. Apply a thin film of compatible fluoropolymer grease to reduce initial breakaway torque, then cycle the valve several times to distribute lubricant evenly. Final torque settings should be checked after the first 100 cycles to compensate for seating adjustments.
Application engineers integrating an airless graco spray gun will find enhanced stability and repeatable stopping points, especially when handling viscous or particulate-laden coatings where momentary shutoff precision is crucial.
Operational feedback confirms that particulate ingress is minimized due to close tolerances and polished ball surfaces. This reduces wear pathways and prevents hardening of residual media in the valve chamber, contributing to reliable functionality over extended service intervals.
For enterprises requiring turnkey fluid management solutions, pairing this stop ball kit with an airless paint sprayer graco can streamline system inventory and simplify training programs by standardizing on familiar components and maintenance procedures.
Final assessments by quality assurance teams emphasize the kit’s role in maintaining regulatory compliance, as leak rates fall well below industry benchmarks. Traceability of materials and batch testing protocols ensure validation records are readily available for audits and safety reviews.
Certified manufacturing processes adhere to ISO 9001 protocols and 100% visual inspection is performed on stop ball geometry and pin alignment. Custom batch testing is offered upon request, including high-pressure cycle simulations to validate performance under exacting conditions. Online documentation and service bulletins assist technicians with installation updates, while extended warranty options and field support teams ensure seamless integration and lifecycle management of your fluid control systems.
With its robust materials, precision machining, and comprehensive support network, this kit reinforces any professional-grade fluid distribution setup. When uptime matters, choosing the 17K490 Kit Stop Ball W/ Pins guarantees dependable performance and expert-level service continuity.
