What is Turbo Dump Valves?
A dump valve also commonly referred to as a blow-off valve, diverter valve or compressor bypass is a pressure release valve that allows air to escape from the equipment that connects the turbocharger on a vehicle to the throttle. The primary functions that dump valves accomplish are making an often desired noise--unique to turbocharged vehicles as air releases, allowing air to escape without backtracking through the airflow chambers, eliminating rattling in the turbocharger caused by backward airflow, increased fuel economy and lowered emissions. Dump valves are actuated piston valves that rely on vacuum and pressure signals to open and close. When an engine is idling or cruising, there is equal pressure on both sides of the valve, meaning there is no need for pressure to be released. To ensure the piston keeps the valve closed at idle, a spring applies pressure to the mechanism.
