Aarding is a business organization, which produces wide range of products. The gas solenoid valves are an electrically operated valve, which cuts off the flow of lpg to the engine when the vehicle is running on petrol mode. The solenoid contains an inbuilt filter, which filters the lpg before getting into the pressure reducer. It works at 6 to 12 v dc and it consumes 0.5 amps current. It is important to properly fix the copper tubes at inlet and outlet without any leakage with ferrule and squeeze nut system. The gas solenoid has a high induction coil wire to render virtually unlimited working life. This is made in vibration resistant model and contains a filter, which filters the lpg flowing through the solenoid.
