$65.08Engineered by Graco to deliver robust performance in fluid delivery systems, the 116473 valve ball vented .250 is a precision component designed for integration into high-flow spray modules. Originating from extensive R&D within industrial fluid control disciplines, this valve features a vented ball design tailored for rapid pressure equilibration and consistent flow profiles under dynamic system loads. Every aspect of the assembly—from the micron-level surface finish to the precision-machined seat geometry—optimizes the passage of viscous and non-viscous media in demanding production environments, ensuring reliable operation across a broad spectrum of pressures and fluid formulations.
The core of the Graco 116473 valve comprises a stainless-steel ball element precisely machined to a surface finish of Ra 0.1 μin, coupled with a hardened steel or hardened alloy valve seat that resists wear and abrasion. Chemical-resistant O-rings and PTFE back-up rings are strategically placed to maintain zero-leak performance over extended cycles. This component integrates seamlessly with an airless sprayer manifold, facilitating minimal dead-leg volume and optimal fluid path alignment for consistent output even at elevated pressures. Material selection is driven by corrosion resistance, bi-directional sealing requirements, and compatibility with a variety of coating chemistries.
Under standard operating conditions, the 116473 ball valve sustains continuous flow rates up to 5 gallons per minute, supporting line pressures to 3000 psi while maintaining volumetric consistency within ±1%. The low-torque actuation profile enhances pump efficiency by reducing backpressure-induced energy losses, minimizing power draw and thermal buildup. In systems processing abrasive or particulate-laden media, the vented design aids in debris migration away from the sealing interface, extending seal longevity and reducing maintenance intervals. Compatibility with professional coatings and solvent blends is validated through accelerated life-cycle testing, ensuring enduring performance in demanding production cycles.
In technical operations, this vented ball valve serves critical roles in spray gun assemblies, pressure regulators, and backpressure control loops within paint circulation systems. Its precision control characteristics make it ideal for finishing lines employing high-viscosity lacquers, epoxy primers, and reactive polyurethane resins. When integrated into closed-loop feedback systems, the component ensures stable flow modulation for repeatable film thickness and uniform surface finish. Engineers typically pair the valve with advanced filter packs to leverage high-pressure filtration upstream, safeguarding the mechanism against contaminants and ensuring uninterrupted operation during extended production runs.
Key design attributes include a vented port diameter of .250 inches, calibrated to alleviate trapped air pockets and optimize pressure recovery during rapid cycling. The ball-to-seat tolerance is held within 5 microns, a specification derived from computational fluid dynamics analyses to minimize turbulence and shear stress on sensitive compounds. The compact footprint allows installation within tight manifolds without inducing stress on the assembly. All contact surfaces undergo precision hone grinding followed by passivation to inhibit surface oxidation, fostering consistent chemical compatibility and reducing particle generation within critical flow paths.
Routine maintenance of the 116473 valve centers on periodic inspection of the vented cavity and seal stack. Technicians should employ ultrasonic cleaning agents compatible with PTFE and nitrile elements to remove build-up without compromising O-ring integrity. Reactivation of venting channels can be accomplished via pressurized solvent flush under controlled flow conditions. When used in conjunction with high-pressure filtration systems, the valve demonstrates extended service life, as particulate ingress is significantly reduced. Proper torque application during assembly ensures consistent seat compression, preserving pump efficiency across thousands of open-close cycles. Seals can be replaced in situ with minimal tooling, reducing system downtime during routine refurbishment cycles.
As a hardened, precision-engineered solution, the Graco 116473 valve ball vented .250 sets a benchmark for reliability and repeatability in fluid control assemblies. Its compatibility with diverse coating chemistries, from waterborne primers to high-solid polyurethanes, underscores its versatility in advanced finishing systems. Engineers leverage its vented architecture to fine-tune pressure differentials, enhancing atomization quality and reducing spray anomalies. The component’s proven track record in industrial manufacturing applications cements its role as a core element within high-performance spray modules, guaranteeing consistent output, reduced downtime, and minimized total cost of ownership in demanding production environments.
When interfacing with variable-speed pumps and automated feedback controllers, it’s crucial to match the valve’s Cv value to flow requirements to avoid cavitation. Calibration protocols typically involve bench testing at incremental pressures to validate sealing behavior and response times under transient loads. Proper orientation in manifold blocks ensures vent channels remain clear and accelerates system commissioning.
