Pressure Retention Valves (PRVs) allow strut assemblies to be shipped and installed pressurized significantly reducing the probability of air spring damage from improper inflation processes. These valves retain a preset amount of air pressure in the event of an in the air sprint in case of compressor failures/compromised air lines or valve block leaks. Older valves may be corroded and prevent the strut from inflating or deflating. This affordable repair can restore the struts functionality.
