Product Description
The 492-187 is a cabin safety valve that automatically relieves excessive pressure differential between the aircraft cabin and ambient atmosphere. This valve protects the fuselage structure from overpressurization damage during normal flight operations. Many designs also incorporate manual dump capability for controlled depressurization.
Typically installed near the outflow valve in pressurization systems, it provides positive pressure relief as a regulatory safeguard. Installation and rigging must follow aircraft maintenance manual specifications and be verified against the Illustrated Parts Catalog.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
