Arnott K-4363 Pressure Retention Valve
The Arnott K-4363 is a brass pressure retention valve (PRV) for air suspension systems that use a front strut-mounted valve. It helps keep a preset amount of air pressure in the strut, which can reduce the risk of air spring damage during service and support proper suspension function when related air system components are worn.
- Pressure retention valve (PRV) for air suspension struts
- Brass construction with male end connections
- Metric design for OE-style air suspension service
- Helps retain air pressure during compressor, line, or valve block issues
- Can restore strut inflation and deflation performance when older valves corrode
- Fits front strut applications on select Bentley, Audi, and Volkswagen models
Built for front strut air suspension service, this valve is used to maintain pressure in the air spring assembly so the vehicle can retain suspension support if the compressor fails, an air line is compromised, or the valve block leaks. Arnott K-4363 is a practical repair for aging valves that may corrode and prevent the strut from inflating or deflating correctly. This part cross-references OE-style numbers such as 3D0616039 and 4E0616039R for the same application.

Common Uses
- Front air strut will not hold pressure after service
- Corroded or sticking valve prevents inflation or deflation
- Air suspension loses support after compressor or line problems
- Valve block leakage affects strut pressure retention
- Restoring function on aging Bentley, Audi, or Volkswagen air suspension systems
Installation Notes
Install on the front strut air suspension assembly only where the vehicle application calls for a pressure retention valve. Verify the OE part number and match the vehicle’s suspension configuration before installation. Because this component interfaces with pressurized air suspension parts, clean sealing surfaces and correct torque practices are important for reliable operation.
