The quality of processing on the threaded brass fittings
In one of the sections of the GNALI BOCIA catalogue, we can find the threaded brass fittings, which allow an easy junction (universally recognised) for the creation of plumbing installations. Processed from a stamped brass semi-finished product that is designed to optimise the costs as well as [...]

Intercepting valves, suitable for all types of fuel
When we’re choosing the intercepting valves to be applied on an installation, we must keep in mind a number of factors. The choice of diameter indeed depends on the type of fuel that we intend to transport in order to feed the generator. Usually, 1/2’’ intercepting valves are used in [...]

Tubular resistors' production process
Starting from a brass alloy of prime quality, our factories create the basis from which the tubular resistors’ range is then created. They can guarantee a complete interchangeability with the other products present on the market. All of this is due to the use, in our factories, of latest [...]

Modularity in brass manifolds' creations
One can easily obtain multiple extensions to an installation with the use of brass manifolds, like the ones that can be found on the GNALI BOCIA catalogue. By being modular, they allow the creation of the necessary number of connections for an agile management of a distribution system. In the [...]

The safety valves designed and produced according to PED guidelines
All of the safety valves produced in our factories are released only if in compliance with the PED (97/23/CE) guidelines criteria, issued by the European community and that regulate the designing and construction of pressure devices. The regulation implies for the safety valves to be tested [...]

Our worldwide products for thermohydraulics
The company GNALI BOCIA can count on a wide range of products for thermohydraulics that are able to satisfy every need in the design and installation phases of both domestic and industrial plants. The vocation for exporting products for thermohydraulics has made it so that they could reach [...]

Using water pressure regulators to save up
One of the complementary functions that the water pressure regulators perform when being inserted into implants, is the one of allowing a considerable saving of water; a great advantage for the costs that all families must be dealing with. Indeed a reduction of 6 bar from the entry to 3 bar in [...]

Various models of flexible rubber tubes, compatible to all gases
 On the GNALI BOCIA’s catalogue, we can fine the flexible rubber tubes range to be used for connecting utilities to a domestic distribution network or to fuel tanks, in the case of portable appliances. The flexible rubber tubes are manufactured with materials compatible with the gases that [...]

Mini control units; UNI 7131 guidelines
For the connection of various LGP tanks destined to the fuelling of a utility implant, the UNI 7131 suggests the use of devices such as the mini control units equipped with two or three stopcocks, which allow to switch cisterns without the dispersion of gas into the environment. The document [...]

Eliminating dissolved gases' bubbles with air vent valves
Once again, we return to the topic of air vent valves; a valid help to eliminate the gases dissolved in the fluid that transports heat in our implants. Studies tell us that if, at the absolute pressure of 1 bar, we increase temperature from 20 °C to 80 °C , the maximum number of litres of [...]
