The operation of shut-off valves
What are the shut-off valves for? The shut-off valves are fundamental components within modern thermo-hydraulic systems. In fact, these devices allow the flow of fuel to be regulated in such a way that the temperature of the fluid is not too high and there is no risk of damage to the system [...]

Gas taps with safety valve: functionality and constitution
The gas taps are fundamental components within every system because they allow the passage, regulation and blocking of the gas inflow at any time using a knob. The safety valves, on the other hand, are necessary components to prevent any malfunction or failure of the system from having harmful [...]

Nickel-plated brass: an excellent choice for multilayer pipe fittings
The starting point: brass Brass is an alloy consisting mainly of Copper (Cu) and Zinc (Zn) which is characterized by high qualities of ductility and malleability, as well as good resistance to corrosion. The machinability of the machine tools is good, but the toughness of the material tends to [...]

The importance of air vent valves in radiators
The radiator is a heat exchanger used inside cars to cool the temperature of the cooling water leaving the engine. Usually it occurs through contact with air and, once the temperature has decreased and an adequate value has been reached, the water continues its cycle and is used again to cool the [...]

The use of the pressure regulator in LPG systems for the automotive sector
The use of LPG or methane gas to power cars is increasingly growing in the global automotive market thanks to both a reduction in costs and an eco-sustainable vision of the transport sector. Focusing on LPG, consumption compared to a classic petrol engine is about 20% higher but the advantage lies [...]

The fuel shut-off valves: operation and advantages
Fuel shut-off valves are important components within a system as they represent a positive action safety device. The main role played by this device is to intercept and block the fuel before it reaches the burner, thus avoiding the boiling temperature of the circuit entering the system from being [...]
