Solenoid Valve

A key component of any turbocharger is the solenoid valve found within the actuator. These electromechanically-operated valves control the flow of exhaust gas throughout the turbocharger housing. The solenoid valve regulates pressure within the turbo and helps improve the overall performance of the vehicle’s engine.

The solenoid valve is a component for controlling the turbocharger speed. When the engine speed increases and obviously the volume of exhaust gas increases, the volume and speed of the gas entering the turbine increases and the turbine speed increases, the increase in speed may be so great that it is dangerous for the turbocharger and the blades. The header valve installed on the turbocharger is for controlling the turbine speed, which means that when the speed needs to be controlled and reduced, this valve opens and the smoke flow changes direction and is not directed to the blade. In other words, when this valve is opened, part of the exhaust leaves the engine without passing through the turbine. This speed of the turbine remains at high speeds. In turbocharged engine, the header valve is positively pressurized. This pressure, which stimulates the header valve, is applied by the solenoid valve, i.e. at the required time, the valve sends positive pressure to the header valve and converts this pressure to move and directs the current to the output path of the turbine. The operation of this valve is such that the header valve has a diaphragm and two chambers, one of the chambers is connected to the air and the other is connected to the solenoid valve by a hose end with a rubber tube and a clamp. With the pressure difference that is created between these two chambers between which the diaphragm is located, the diaphragm and consequently the interface and the arm of the valve moves and the valve opens.
