3. LPG Tank Valves: Valves fitted to the tank allows gas to enter the tank through the filling valve and automatically stops filling when the tank is 80% full. There is a level indicator plus a manual service tap with a solenoid valve which closes when not running on lpg or when the engine is not running. A pressure relief valve stops excessive pressure build up in the tank .
All the valves are enclosed in a sealed sub compartment to avoid any gas leaking into the car (not necessary when the tank is mounted outside the car).

DESCRIPTION OF MULTI VALVE INSTALLED IN THE LPG TANK ILLUSTRATING THE PICTURE BELOW

1/ Fuel level gauge. Electronic level indicator. The level indicator should be chosen according to the adopted ECU system.

2 / Non-return valve at the inlet. The non-return device is equipped with a double safety system: the first non-return valve is integrated in the 80% filling limiter,, the second device is located in the inlet fitting. These devices are aimed to avoid the back flow of gas from the tank toward the outlet of the filling device

3/ Pressure relief valve (PRV). The PRV is a safety device aimed to limit the maximum pressure inside the tank to 2.7 ± 0.1 MPa. The PRV is a valve with a retaining spring allowing, in case of overpressure, the discharge of the LPG from the tank in vapor phase. Pressure relief device is a safety device equipped with a thermo fuse element which melts at a pre-set temperature of 120 ° C ± 10 ° C. In case of fire, the fuse melts and opens a hole for the fast release of the LPG from the tank, preventing the risk of an explosion.

4/ Manual valve. The manual valve intercepts the outlet gas circuit upstream of the solenoid valve and is aimed to the maintenance of the solenoid valve. Excess flow valve is located in the withdrawal circuit , upstream the solenoid valve and is aimed to block the flow of LPG in the event of an accidental breakage of the LPG piping . After its intervention, for the automatic resetting of the valve, a residual flow is allowed.

5/ Shut-off solenoid valve This device is aimed stop the gas flow when one of the following conditions occurs: the engine is switched off or is working in petrol and the electric supply to the solenoid is switched off; in this condition, a spring inside the solenoid valve maintains the moving core in the closing position; while switching to LPG, the electric supply to the solenoid is switched on and the solenoid generates a magnetic field that attracts the plunger, allowing the opening of the multivalve hole and, consequently, the LPG flow.
