FAQ

What does a pop‑off relief valve do?

A pop‑off relief valve automatically releases excess pressure when the set pressure is exceeded, preventing damage to compressors and downstream equipment. The pop‑off feature also provides a visual cue that the valve has opened.

Can this valve be used with oil‑free compressors?

Yes, the solid brass body is compatible with both oil‑free and oil‑lubricated compressors, offering reliable performance regardless of the lubrication method.

How do I install the valve?

Installation is straightforward: thread the male 3/8″ NPT end into the corresponding female fitting, ensure a tight seal, and verify that the valve is oriented correctly for pressure relief. No additional tools are required.

What maintenance is required?

The valve is designed for low‑maintenance operation. Periodic visual inspections for wear or corrosion and occasional cleaning of the threads are sufficient to keep it functioning optimally.
