$19.1Graco 17A563 ValveThermal Relief Tp Series represents a major step forward in safeguarding fluid circuits from dangerous overpressure scenarios caused by thermal expansion. By incorporating a precisely calibrated relief mechanism, this valve ensures that any elevated pressure within paint and coating supply lines is safely vented before it can compromise system integrity. Certified to comply with ISO 9001 manufacturing standards and offering multiple setpoint options, it accommodates diverse fluid chemistries—from solvent-based enamels to waterborne lacquers. Ideal for heavy-duty applications, it features a compact profile, robust materials, and seamless integration into existing manifolds. Reduced footprint in congested equipment rooms simplifies routing and installation. Multiple setpoint configurations, from 150 psi to 1000 psi, enable precise matching to system requirements. Expertly engineered for reliability, it helps maintain consistent output and protects pump components from sudden spikes, while its ergonomic design facilitates quick access during periodic inspection or replacement.
Meticulous attention to material selection allows the Graco 17A563 ValveThermal Relief Tp Series to withstand harsh coating environments. A high-grade stainless steel body resists corrosion and abrasion, while a polymer seating surface ensures leak-free operation. Internal components are micro-finished to eliminate particulate shedding, preventing contamination downstream. Cycle endurance tests exceeding 100,000 actuations confirm long-term stability, and smooth internal contours minimize fluid turbulence and pressure drop. A precision spring assembly delivers consistent actuation at pre-set pressures, with minimal hysteresis. Machining tolerances are held to rigorous standards, guaranteeing interchangeability and simple field-serviceability. Built to meet API 598 standards, this valve offers field-proven reliability and low maintenance costs. This commitment to quality manifests in improved cycle life and reduced downtime across industrial spray systems.
Operators running a graco x7 airless paint sprayer can integrate this relief valve to maintain optimal fluid flow without risking pump overload. Rapid response to rising pressure conditions protects sensitive custom tips and hoses, ensuring that coating operations remain uninterrupted. Dynamic flow testing shows that the valve vents excess pressure within milliseconds, preventing backpressure that can distort spray patterns or damage seals. Flow characterization indicates vent rates up to 0.5 SCFM at full relief, and setpoint tolerances remain within ±5 psi. Ideal for high-temperature operations up to 80 °C without performance drift, it supports demanding production environments. Engineers also value the clear performance charts provided in comprehensive documentation.
Mounting the Graco 17A563 ValveThermal Relief Tp Series requires minimal tools and familiar torque values. Standard NPT threads and adaptable port sizes allow direct connection to most pump outlets or manifold blocks. A comprehensive service manual references the graco 395 parts diagram for users who want to cross-reference assembly drawings or order replacement components. Use an approved thread sealant or PTFE tape rated for coatings to ensure a leak-proof joint, applying anti-seize to prevent galling in high-temperature zones. Proper orientation is critical: valve ports must face downstream from heat sources, and access clearance should accommodate occasional inspection. Incorporate a safety relief vent line to direct discharged fluid safely away from operators and equipment. Tighten with a calibrated torque wrench to avoid gasket extrusions and ensure a reliable seal.
Integration possibilities extend beyond conventional airless sprayers, supporting lubrication systems, chemical processing lines, and high-pressure wash-down applications. Equipment specialists often pair this valve with a graco 395 paint sprayer to deliver consistent material rheology under fluctuating temperatures. Its neutral vent design channels excess fluid into a containment vessel, making it suitable for solvent-based or waterborne formulations. Various industries, from automotive refinishing to industrial coatings, benefit from its versatility. Users appreciate its adaptability when retrofitting multi-gun manifolds or upgrading aging OEM relief valves without extensive piping modifications. Clear labeling and standardized ports further streamline changeovers and reduce installation errors. Compact design and minimal dead volume make it well-suited for automated spray robotics and rapid color-change applications.
Routine inspection of vent ports and seal surfaces keeps the Graco 17A563 ValveThermal Relief Tp Series operating at peak performance. Clean any buildup of paint residue or debris that could hinder spring movement. Replacement seals and springs are available as service kits, allowing technicians to refresh critical components quickly. Common failure modes such as spring fatigue or seat erosion can be addressed promptly using factory-specified spare parts. For optimal reliability, schedule annual function checks and calibrations using a certified test bench. Comprehensive technical bulletins, detailed dimension drawings, and parts catalogs support preventive maintenance planning. Incorporate remote monitoring accessories to track relief events in real time and schedule proactive service. Tech support lines are available to assist with troubleshooting or installation queries.
Robust design, precise actuation, and broad compatibility make this relief valve an indispensable asset for demanding fluid handling tasks. Maintenance teams benefit from straightforward service procedures, while operations managers gain peace of mind knowing that thermal pressure spikes are managed automatically. Compliance with industry standards and rigorous in-house testing underscores its superiority in performance-critical sectors.
