The GRACO 237062 VALVE, RELIEF is a pressure relief valve designed to automatically relieve system pressure at a specified rating, protecting GRACO equipment from overpressure. It is constructed from stainless steel and PTFE materials, making it compatible with catalyst, waterborne, and other finishing materials. This valve is essential for maintaining system safety and optimal performance in spray and pump systems.

Key Features:

• Spring-loaded needle valve
• 1/2 NPT (inlet/outlet), 1/2 NPT (relief port)
• Stainless steel, PTFE, tungsten carbide (nickel binder), UHMWPE (model 24W475)
• Cracking pressure: 3000 psi; Suggested working pressure range: 1800–2300 psi
• Catalyst, waterborne, and other finishing materials
• Compact and easy to install
• Low wear and long life due to tungsten and carbide materials
• Noise level <70 dBA
• Reliable overpressure protection
• Easy maintenance and cleaning recommended for filled materials

Applications:
Used in GRACO proportioners, pumps, and spray systems to prevent overpressurization and ensure safe operation in industrial and commercial finishing applications.

Installation Notes:

• Using a genuine GRACO part ensures optimal performance, safety, and compatibility with GRACO equipment.
• Relieve air and fluid pressure in the system before servicing the valve
• Ensure system working pressure is within the suggested range (1800–2300 psi)
• Do not modify, remove, or plug the pressure relief valve
• Clean the valve daily when using filled materials to prevent obstruction
• Ground the entire system, including the valve, when pumping flammable liquids
• Torque inlet/outlet to 50–60 ft-lb (68–81 Nm), relief port to 13–15 ft-lb (18–20 Nm)
• Inspect and clean regularly, especially when using filled materials
• Replace seals if leakage is observed
• Apply appropriate lubricant during installation and maintenance
• Keep warning labels intact and visible
