Q: Can I use this on any spray gun?
A: Yes, provided your gun uses 1/4 inch NPS connections and your inlet pressures stay within limits. However, it’s optimized for HVLP or high efficiency systems due to its design for minimal pressure drop.
Q: What if the digital display fails or needs calibration?
A: The catalog suggests the gauge can be zeroed or recalibrated if it shows nonzero when not under pressure. Calibrate per instructions in user manual.
Q: Does the auto-off feature interfere with spraying?
A: The display turns off after ~45 seconds of inactivity, but the valve continues to control pressure. You can press "On" to reactivate the display without affecting spray pressure.
