Powerdown Hcv W/Dump Includes 3/8 - 1/4Height control valves (HCVs) are the brains of an air suspension system. They sense ride height relative to the chassis and control airflow to the air springs to maintain the correct suspension height under varying loads. A slow, sticking or failed HCV means the suspension cannot respond quickly enough to load changes - eliminating the load distribution, ride quality and tyre life benefits that air suspension is designed to provide.Powerdown distributes Hadley and Ridewell HCVs - two brands with deep OEM supply relationships in the North American heavy truck and trailer market, where air suspension compliance standards are among the most stringent in the world. Both brands are proven across millions of kilometres of Australian operation. Hadley and Ridewell brands - OEM-quality performance proven in heavy vehicle air suspension Instant-response and delayed-response configurations to suit different suspension requirements Cabin and trailer/axle mounting configurations available across the range Hadley SmartValve electronic height control for major OEM truck platforms Correct HCV function maintains legal ride height and load distribution compliance Failed or slow HCV eliminates all benefits of air suspension - replace promptly Signs of HCV failure: Vehicle sits at incorrect ride height, suspension takes a long time to adjust after loading or unloading, one corner is consistently lower than others, air springs bottoming out, or compressor running continuously. HCVs should be serviced or replaced every 400,000km or when response time becomes noticeably slow.Part number: 6310BAAA07 | Vendor: Powerdown | Australian designed for heavy commercial vehicles | Technical enquiries: 02 4949 0000 | [email protected]
