For RZR XP Refit Turbo Aluminum Blow Off Valve (Diverter Valve) Product material: high quality aluminum
colour:black Product model: BOV1023 Suitable for models: For RZR XP product description: The pressure relief valve we often talk about should be called the overspeed shut-off valve. The valve body is connected with 3 pipelines: one with the intake hose, one with the booster line between the exhaust turbine and the intercooler, and the third connection. Vacuum line for the engine. This valve body of our original car is designed and manufactured by BOSCH in Germany, and it is made of plastic material due to cost considerations. The over-speed shut-off valve is controlled by vacuum. During the accelerator acceleration of our feet, the throttle is opened and the exhaust turbine starts working at 1750RPM. At about 3000RPM, the turbine can reach the maximum boost pressure. But when we shift gears or brakes, The throttle will be closed, and the throttle opening will decrease rapidly until the idle state. At this time, the turbine will still run at high speed due to inertia, and the speed will reach tens of thousands of RPM. The high-pressure air generated cannot enter the engine. If the high-pressure air in this pipeline is not timely Leakage can cause damage to the turbine, throttle, or piping. When the throttle is closed, the vacuum control overspeed shut-off valve opens, and the high-pressure air between the turbine and the throttle is quickly drained into the intake line of the turbine. Pressure relief valve function: The main purpose of the pressure relief valve is to improve the speed of response and the reliability of the action, rather than increase the power.
