Water couplings derived from top quality materials
Water couplings in brass are among the items most widely used and most readily available commercially, capable due to their universality and flexibility of facilitating the installers’ life. The market difference made by water couplings is certainly due to the selling price, which in the [...]

Pipe for methane gas and the reference norm
In GNALI BOCIA’s catalogue, we may find the pipe for methane gas realized in PVC capable of resisting the corrosive action of gas itself. The construction is of the multi-layer type and between the two pipes, internal and external, the standard demands that a woven or spiralled reinforcement [...]

Modularity of the brass manifold for heating
Whether we have to realize a radiator system or a floor system, the use of a manifold for heating realized in brass with shut-off cocks is almost a necessity. The presence of valves on the manifold for heating, in fact, enables the splitting of the flow on every branch plant, thereby allowing [...]

Power packs to facilitate the change of tanks
Do you need to avoid being without gas at home or while in motion on your trailer or camper? Would you like an easy way of replacing your tanks without dangerous losses and without interrupting the cooking of your dinner? The best method is to use one of the power packs produced in GNALI [...]

Threaded brass fittings, a fundamental range in installations
Threaded brass fittings are a necessary component in the realization of a domestic or industrial plant that is capable of acting as conduit for water and non-corrosive fluids or for gas. In order to reduce the impact in any event corrosive of water, they may also be supplied superficially [...]

Check valves in order to prevent energy dispersions
The function of the check valve is to prevent hot fluid from reversing towards the supply pipe; in hot water heaters it is important, inasmuch as its absence would allow taps closed to heated water to flow towards the water main. In these applications, the check valve is combined with a safety [...]

The versatility of use of valves with burner
In the most varied scenarios where the use of flames is requested for manufacturing operations, we may for instance think in this connection of the cleaning of moulds for the manufacturing of plastic, we discover the usefulness of valves with burner which, linked to a gas tank, might be used in [...]

Linking more gas tanks with the tubular units
You have no problems of space? If so, in order to link more than one tank to your gas distribution plant you can use tubular units, which enable the simultaneous installation of up to 4 tanks on the same line. Every tank has its stopcock that is needed for insulation and for replacing the [...]

The practicality of installing fittings for multilayer pipes
Among the products in the GNALI BOCIA catalogue, we find a complete range of fittings for multilayer pipes produced in order to ensure the realization of any type of sanitary or heating plant, by using new generation pipes which, with their aluminium core covered by two layers of plastic [...]

Gas valves with closing command that avoids accidental manoeuvres
They are often equated in hasty parlance to the taps needed for regulation, but the Gnali Bocia catalogue includes a specific section on gas valves. This juxtaposition, however, is not wrong, since taps, too, are gas valves; we find in fact realizations that are usually needle-shaped so as to [...]
