Frequently Asked Questions

The air safety relief valve is a crucial safety device that prevents catastrophic failure of air system components by automatically venting excess pressure. This protects regulators, gauges, and other components from damage due to overpressure situations.

Signs include the valve leaking at normal operating pressures, failing to activate during overpressure conditions, or visible damage. Regular testing and replacement as part of preventive maintenance ensures your safety relief valve functions properly when needed.

No, this safety relief valve is factory-set to the specific pressure rating required for your Graco sprayer model. Tampering with or adjusting the pressure setting can compromise safety and should never be attempted.

Safety relief valves should be tested regularly according to Graco's maintenance schedule, typically every 6-12 months depending on usage. If the valve activates during an overpressure event, it should be inspected and possibly replaced to ensure continued reliability.
