Product Overview

The Graco 15H834 Ball Neo/SST Core 2.25″ is engineered for high-performance fluid handling in demanding pump systems. Its robust construction ensures reliable sealing, consistent flow, and extended service life.

  • Neoprene elastomer interface bonded to polished stainless steel for durability
  • 2.25″ diameter for high flow capacity
  • Low-friction surface for minimal pressure drop
  • Dynamic sealing under high-pressure cycling
  • Corrosion-resistant core suitable for various coatings

Material & Construction

The stainless steel core is precision-ground for spherical accuracy and polished to a smooth, low-roughness finish. The neoprene (NEO) elastomer is vulcanized to the core, maintaining preload stability even under high-pressure cycling and mechanical stress.

Performance & Reliability

This check ball delivers high-flow performance and tight sealing under repeated cycles. It resists wear from abrasive coatings and maintains operational efficiency over long-term use.

Applications

Ideal for use in piston, diaphragm, and high-pressure sprayer pumps handling architectural, industrial, marine, and specialty coatings. Performs well in systems with high-volume or abrasive media.

Installation & Maintenance

  • Inspect valve housing and seat before installation
  • Clean seating surfaces to ensure optimal sealing
  • Use light, compatible assembly lubricant if necessary
  • Regular inspection for elastomer wear or scoring
  • Maintain upstream filtration (40-micron or finer) for abrasive media

Frequently Asked Questions

The 2.25″ diameter allows for higher flow capacity and is designed for large-capacity pumps, whereas smaller balls are used in lighter-duty or lower-flow systems.

Yes, the NEO elastomer is chemically resistant and suitable for a wide range of coatings, including solvents, water-based paints, and high-solid formulations.

Replacement depends on usage, media, and system filtration. Regular inspection is recommended; many users replace it every 500 operating hours for high-duty applications.

This ball is specifically designed for Graco high-pressure systems. Use in non-Graco pumps is not recommended unless the pump’s valve housing matches Graco specifications.
