Pressure Relief Valves


Pressure Relief Valves (PRVs) are safety devices designed to protect aircraft systems from overpressure conditions. They are installed in various locations throughout the aircraft, including fuel tanks, hydraulic systems, and pneumatic systems. PRVs are designed to open when the pressure in the system exceeds a predetermined level, allowing excess pressure to escape and preventing damage to the system. They are typically spring-loaded and may be set to open at a specific pressure or range of pressures. PRVs are an essential component of aircraft safety systems and are subject to rigorous testing and maintenance requirements.
