CNG-NGV Reducer

CNG-NGV Reducer (or Pressure Regulator) is an electronic control device that reduces CNG pressure from 200 bar to 3-5 bar and producing a regular flow of gas fuel for the engine's need. It is equipped with three CNG reduction stages that allow stability at both high and low pressures and a high-pressure solenoid valve upstream from the first stage. The absorption of heat, taken from parts of the regulator, heated with a tap-in engine coolant, prevents the sensor-diaphragm from freezing up during the fall in pressure phase. The flow of gas necessary for engine idling is obtained throught the main gas pipe thanks to the vacuum generated by the Mixer. It includes an electronic starting device with a built-in safety system that trips and shuts off the gas solenoid valves if the engine is switched off or even when it stalls.
