A blowoff valve (BOV), dump valve or compressor bypass valve (CBV) is a pressure release system present in most turbocharged engines.
ISO 4217 code for the Bolivian MVDOL. It is a unit of account in Bolivia that does not circulate. It is adjusted for inflation relative to the U.S. dollar so that its value does not change with inflation. Because of this stability, financial instruments in Bolivia are quoted in BOV terms. MVDOL is a Spanish abbreviation for boliviano maintaining value with respect to the dollar. The basic principles of a BOV are the same for a gasoline and diesel engines, the difference is that a diesel system needs some electronics to work properly. With either setup, the most challenging part of the installation is welding the mating flange onto the CAC. Here, TurboSmart’s newest BOV, “Big Bubba” is shown on a 2004 Cummins. There is still boost being sent to the top of the BOV. What’s different in a diesel system is that the air is sent through a solenoid. When the solenoid is off, boost pressure passes through uninterrupted GReddy Blow Off Valves are easily adjustable to eliminate compressor surge and preventing premature boost leakage, while increasing boost response between shifts. Each valve is made of durable cast and billet aluminum frame and the valve to diaphragm ratio provides performance that cheap piston types cannot offer.  From Wikipedia, the free encyclopedia. A blowoff valve (BOV), dump valve or compressor bypass valve (CBV) is a pressure release system present in most turbocharged engines. Its purpose is to prevent compressor surge, and reduce wear on the turbocharger and engine. A blowoff valve is connected by a vacuum hose to the intake manifold after the throttle plate. When the throttle is closed, the relative manifold pressure drops below atmospheric pressure and the resulting pressure differential operates the blowoff valve's piston. Every day thousands of users submit information to us about which programs they use to open specific types of files. While we do not yet have a description of the BOV file format and what it is normally used for, we do know which programs are known to open these files. See the list of programs recommended by our users below.  When the throttle is closed, a vacuum forms in the manifold. This in combination with the pressurized air from the turbocharger moves the piston in the valve up, releasing the pressure into the inlet of the turbo (Recirc.) or the atmosphere (BOV). A blowoff valve is connected by a vacuum hose to the intake manifold after the throttle plate. When the throttle is closed, the relative manifold pressure drops below atmospheric pressure and the resulting pressure differential operates the blowoff valve's piston. A compressor bypass valve (CBV), also known as a pressure relief valve or diverter valve, is a manifold vacuum-actuated valve designed to release pressure in the intake system of a turbocharged vehicle when the throttle is lifted or closed. A blowoff valve is connected by a vacuum hose to the intake manifold after the throttle plate. When the throttle is closed, the relative manifold pressure drops below atmospheric pressure and the resulting pressure differential operates the blowoff valve's piston. One of the most important additions you can make to a turbocharged engine is the installation of a turbo blow off valve. While many factory turbocharged vehicles will come with a BOV from the factory, they are not commonly included in most low-boost aftermarket turbo kits. While they are not absolutely required in these low boost situations, a BOV is a good idea for any turbocharged application. A Question of Performance and Durability. Turbochargers can introduce large amounts of pressurized air into your engine. Installing a vent-to-atmosphere type of BOV or VTA BOV will cause incorrect air readings and overly rich idle, stumbling and stalling problems. MAF equipped vehicles should always have their BOV properly recirculated back into the intake tract to prevent these problems.
