VIAIR 92205 Hi-Temp Safety Valve

The VIAIR 92205 is a 205 PSI rated safety valve with a 1/4 inch male NPT thread designed for compressed air systems. It provides over-pressure protection in a compact brass body built for high temperature environments. The valve carries California Proposition 65 notices for chemicals known to cause cancer and reproductive harm.

Automotive air system builders

This valve suits installers adding over-pressure protection to onboard air compressors, air suspension kits or pneumatic tool circuits that operate up to 205 PSI. It is not for hydraulic lines, liquid service or systems requiring a different thread form or pressure setting. Buyers needing a lower cracking pressure or a female port should select a different model.

Sustained high-temperature operation

The hi-temp rating means the valve maintains its seal and opening characteristics during extended compressor cycles that raise component temperatures. It relieves excess pressure cleanly without the seat degradation seen in standard valves under continuous heat. The 1/4 inch NPT connection stays tight through thermal expansion cycles.

Questions about this item

What thread size and type must the tank or manifold have to accept this 1/4" NPT safety valve?

The valve has a 1/4" male NPT thread, so the mating port must be a 1/4" female NPT fitting.

Will the 205 PSI relief setting interfere with a compressor that cuts out at a lower pressure?

The valve opens at 205 PSI; it will not vent until system pressure reaches that level, so a lower cut-out pressure is unaffected.

How can I confirm the valve is functional after installation?

Pressurise the system and observe that no air escapes until pressure approaches 205 PSI, at which point the valve should vent.
