Closing the main valve (Shut-off/Turn-off) A.) Round âwheelâ handle valves will turn-off by turning the handle to the right (clockwise). It may take 2 or more full revolutions. B.) Slowly turn level handle valves Â¼ turn, until the handle it not parallel with the pipe.
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). 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.
