Material: 6063-T6 aluminum alloy color: black Suitable for: turbo car special when the turbine action, the internal will produce extremely high pressure. Although the turbine itself has the aperture to release high-pressure gas, it is still somewhat insufficient in the face of continuous pressurization. By means of pressure relief valve, high-pressure gas can be quickly released to facilitate the next pressurization action. This can not only protect the turbine, but also eliminate part of the phenomenon of turbine hysteresis. Advantages 1. Enhanced torque of relief valve, effective protection 2. Protection of turbine service life 3. Lift turbine reaction to enhance power supply response
