LPG Vacuum Pressure Reducer
The New LPG vacuum reducer has been designed to be installed in all carburettor vehicles. As for the electronic reducer the liquid LPG arriving from the LPG solenoid through a copper pipe enters the LPG Pressure reducer, to its 1st stage vaporization-reduction chamber. In the first stage LPG is firstly vaporized and successively reduced in pressure. The second stage chamber is very sensible to the vacuum pressure. The vacuum pressure causes the flow of LPG to the engine to increase or decrease depending on the pressure difference. Any pressure difference is transferred to the second stage chamber and the membrane will allows for a greater flow of gas to enter the engine. The small coil mounted on top of the second stage cover is used for the function of choke allowing small quantities of LPG at the time of engine start.

The pressure reducer-vaporizer has the main function to convert LPG from its liquid state to a gaseous state and regulating the LPG pressure in the process. The reducer is a device with two Gas compartment and a water circuit for heat exchange. Liquid LPG arriving from the LPG solenoid through a copper pipe enters the LPG Pressure reducer, to its 1st stage vaporization-reduction chamber.

The LPG Solenoid Valve is an electromagnetic device that stops the flow of LPG when the engine is stopped or operated with petrol.

The solenoid LPG Valve is composed of :
1. NBR seals to guarantee absolute safety
2. High thermal induction coil wire to render its working life virtually unlimited
3. Self extinguishing coil covering resin
4. Gas filter made with a fine filter paper material.
5. Vibration resistance.
6. Multiple fitting position.
Please follow installation, maintenance and safety precaution instructions

The Petrol Solenoid Valve is an electromagnetic device widely used in carburettor vehicles. Its function is to stop the flow of Petrol when vehicle is running with LPG and vice versa when the vehicle is operated with Petrol. The petrol Solenoid valve is installed in the line of Petrol fuel near the engine compartment. The Petrol Solenoid valve is normally closed when electricity is switched off. It is basically composed of a shutter operated by a magnetic coil and two nipples. It is also equipped with an emergency device to manually reset the petrol flow in case of a break down in the electrical system.

This is a three position electronic switch. The first position is PETROL and the second is LPG. Obviously when positioning the switch on petrol the switch will close the LPG Solenoid Valve and it will open the Petrol Solenoid Valve and vice versa. The Mid position of the switch (third position) is use to maintain the LPG and the Petrol Solenoid valves in the OFF position until the carburettor uses the small Petrol reserve. With a carburettor engine gas switching is always done manually. The switch for carburettor engines also has a safety feature, it stops the gas flow to the engine when engine accidentally stops.

The mixer is an important part of the L.P.G. system. The mixer has the function of providing the correct AIR-FUEL ratio  suitable for a correct combustion. It is connected to the LPG pressure reducer by a gas hose thru an adjuster or in the case of a fuel injected vehicle thru a step by step motor.

The way the mixer is installed is very important and its correct positioning is fundamental for a successful L.P.G. system. Given the level of specialisation and function that has been achieved in the car industry, it is clear that mixers are subject to continuous development.

The mixer in car with carburettor has an extremely importance. The right AIR- FUEL ration depends on the mixer and this is the reason for the existence of so many versions bearing so many shapes. The mixer for vehicles equipped with a carburetor may be manufactured with  a specific Venturi or by implanting a nozzle in the proximity of the carburettor's  original Venturi. The nozzle system type mixer can perform very well if executed with care and knowledge. In any way, is good to remember, that this system is not always possible to adapt to all carburetors and if not properly installed it may create irreversible damages to the carburetor. Therefore, it is advisable obtain proper training prior to any installation of this type.

The Multivalve is the component of the L.P.G. system which is installed on the Reservoir’s flange. Multivalve is available in many sizes. Normally it is available in accordance with  the dimensions of the Reservoirs available in the market.

The Multivalve has its name from the fact that its body houses a number of valves with different functions

The main valves are :

1) Service manual valve.
2) 80% limit filler valve.
3) No Return Valve (Check Valve)
4) Excess Flow Valve
5) Cut off valve (available in the new generation Multivalves)
6) Thermal Fuse Valve. (available in the new generation Multivalve).
7) Safety Valve (Pressure Valve)

The Multivalve is also equipped with a rod system that actuates a magnet, which depending in its position will indicate the level of fuel contained in the reservoir.
