        Throttle Plates and Shafts

        Investing heavily in new technologies, GVS has become a leading firm worldwide for high-precision mechanical processing with large and very large volumes (1-100 million pcs) in the manufacturing of valves, shafts and throttle bodies in aluminium, brass, special alloys and plastics.

        Regulating the air/fuel mix by increasing or decreasing the volume of incoming air, throttle body system butterfly valves can be mechanical, electromotive or fully electronic.

        Valves can be mechanically linked to the accelerator pedal or can be controlled through a combination of accelerator pedal and ECU or exclusively through electronic signal from the engine management system.
