R89 / R90 Main Features

  • Suitable for high-powered engines from 0.5 litres to 6 litres (500 to 6,000 cc)
  • Powerful and very efficient heat exchanger
  • Servo-assisted pressure regulator that guarantee regular dynamic behaviour and excellent driving performance under all working conditions
  • Double gas outlet for high-powered engines (plug supplied for single outlet use)
  • Interception solenoid valve stops gas still contained in the reducer when the engine is switched off
  • By-pass register to avoid a sudden switching off of the engine when put in neutral or when the car brakes or turns unexpectedly
  • Availability of HP (High Power) version for high-powered engines

R89 Compressed Natural Gas (CNG) Pressure Reducer

R89

The R89 pressure reducer has been designed by OMVL to supply fuel-injected vehicles with CNG, and also offers excellent performance for carburetted vehicles. R89 reduces the pressure of the gas contained in the cylinder (220 bar) to a definite value which is kept constant under all working conditions.

The reducer is equipped with a sensitive patented servo system regulating the main gas flow and reacting with precision to all engine requirements. R89 features a stabiliser device which guarantees a regular gas supply through strong variations of pressure in the cylinder (from 200 to a few bar).

The reducer also features a bypass register to avoid engine shut-off when put in neutral or when the car brakes or turns unexpectedly. The R89 device has a thermostatic valve which maintains the temperature of the coolant liquid in the reducer at a value between 45 and 50°C (~120°F) independently from the temperature of the liquid in the radiator. Furthermore, with an efficient electric heater (optional), the connection with the cooling circuit of the car is not required in places where the weather conditions are moderate.

R89 is a powerful reducer, suitable for high-powered cars (from 0.5 L to 6 L [500 to 6,000 cc]), reliable under all working conditions and provides superior performance in comfort and driveability.

Approved in accordance with the safety regulations for gas-systems (UN/ECE 110R –00), R89 keeps emissions well within the limits established by the strictest standards (EURO4).

R90 Liquid Petroleum Gas (LPG) Pressure Reducer

R90

R90 is a pressure reducer / vaporiser developed by OMVL to supply fuel-injected vehicles with LPG (also known as propane), and also offers excellent performance on carburetted vehicles.

Thanks to a powerful heat exchanger, R90 ensures full vaporisation of LPG—in order to guarantee regular and dynamic behaviour of the engine, even in particularly cold conditions—and reduces the gas pressure to a definite value, kept constant under all working conditions.

The R90 reducer is equipped with a sensitive patented pilot-system, which regulates the main gas flow and reacts with promptness and precision to all engine requirements.

The reducer has a bypass register to avoid engine suddenly shut-off when put in neutral or when the car brakes or turns unexpectedly.

R90 is a powerful reducer, suitable for high-powered cars (from 500 to 6,000 cc), reliable under all working conditions, and guarantees excellent performance in terms of comfort and driveability.

Approved in accordance with safety regulations for gas-systems (UN/ECE 110R –01), R90 keeps emissions well within the limits established by the strictest standards (EURO4).
