Frequently Asked Questions

The valve opens automatically when air pressure exceeds its set point (130 PSI), preventing over-pressurization and protecting the air motor and control system from damage.

No. The 114003 is an air system safety valve. It is not designed for relieving paint or fluid pressure and should only be used on the air-motor side of the system.

It is strongly recommended to use the OEM Graco valve to ensure the correct pressure relief rating and safe operation. Incorrect valves may not trigger reliably and can cause equipment damage or safety hazards.

The 114003 valve is typically installed within the air control module or on the air motor inlet side of Graco proportional and pump systems. Placement may vary depending on model design.

If you're unsure whether this valve fits your system, verify through your machine’s parts manual or contact Graco technical support for confirmation.
