VIAIR 92145 Safety Valve 145 PSI
This VIAIR 92145 safety valve is a pressure-relief component rated to 145 PSI for mobile pneumatic systems. It features a 1/4-inch male NPT thread for direct installation into air tanks or compressor heads. The valve is designed for 12-volt and 24-volt automotive applications worldwide. It suits workshops and vehicle owners maintaining air suspension or on-board air systems.
145 PSI Hi-Temp Rated Safety Valve
The hi-temp rating allows the valve to operate reliably in harsh environments from arctic climates to desert conditions. Its pressure setting protects downstream components by venting excess air when system pressure reaches 145 PSI. The 1/4-inch male NPT connection ensures a secure, leak-free fit without additional adapters. This accessory supports the reliability VIAIR compressors are known for in OEM and aftermarket use.
For 12-volt and 24-volt pneumatic systems
This valve suits technicians and owners servicing VIAIR compressors or compatible air tanks requiring a 145 PSI relief point. It is not for systems operating at different pressure ratings or needing alternative thread sizes. Buyers who want more storage capacity or a different pressure setting should look at other components. The set selling unit provides the valve ready for installation.

Questions about this item
Does the 145 PSI safety valve need periodic replacement or maintenance?
The 145 PSI safety valve is a mechanical relief device; inspect it during routine air-system checks and replace it if it weeps, fails to reseat, or shows corrosion on the 1/4‑in NPT threads.
What is the first limit reached when the valve operates continuously at its 145 PSI setting?
The valve opens at 145 PSI and vents excess pressure; sustained operation at that set point means the compressor runs continuously, so the thermal limit of the compressor — not the valve — is reached first.
How much heat or noise does the 92145 safety valve add when the system runs all day?
The valve itself generates no heat or noise until it lifts at 145 PSI; during a lift event it vents air with a brief hiss, then reseats silently once pressure drops below the set point.
