The natural gas regulator is specifically designed to meet the most stringent legal requirements set down for car related gaseous injection fuel supply systems.
The regulator constantly adjusts the pressure of the natural gas in gas cylinders to the pressure required by the injection system.
  The regulator is capable of supplying the required amount of gas under all of the engine's operating conditions and also allows for a precise regulation of exit pressure.
  The regulator is a two-stage membrane fitted type of regulator, compensated (in the version for aspired engines) in order to keep the fall in pressure in the injection device constant with the engine's throttle valve.
  It is also fitted with a water/gas heat exchanger, gas solenoid valve with incorporated filter and safety valve.
  The regulator is available in different versions which span a comprehensive range of pressures which go from 1 to 3 bar (100 - 300 kPa).
