VIAIR 92250 Safety Valve 250 PSI

Product Identity

The VIAIR 92250 is a 250 PSI high-temperature rated safety valve designed for mobile pneumatic systems. It suits installers and maintainers of 12- and 24-volt automotive air compressor setups who need a reliable pressure relief component. The valve uses a 1/4 inch male NPT thread for direct installation into compatible ports. Supplied as a set, it integrates with VIAIR compressor systems used worldwide.

Critical Specification

The decisive figure is the 250 PSI pressure rating, which must match the maximum operating pressure of the air system it protects. A valve rated lower would vent prematurely, while one rated higher could allow dangerous over-pressurisation. The high-temperature rating ensures the valve maintains calibration under the heat generated by continuous compressor duty cycles. No other specification overrides this pressure limit for safety compliance.

Fit And Alternatives

This valve suits builders fitting VIAIR compressors or similar mobile pneumatic kits that require a 250 PSI relief point with a 1/4 inch male NPT connection. It is not for buyers who need a different pressure setting, a female thread, or a larger port size for higher flow capacity. Systems running at significantly lower pressures should select a valve matched to their specific relief requirement to avoid nuisance venting.
