Electrical resistors' characteristics
Electrical resistors were created to fulfill the need to heat water or other fluids and especially to use water in domestic settings. One of the examples that springs to mind is the use of electrical resistors inside boilers or water heaters. The Gnali Bocia catalogue includes different types [...]

The use of water manifolds in heating installations
Water manifolds are essential components for floor heating installations of homes and offices and for systems that convey heated water in working environments of different types. This is why Gnali Bocia designs and sells different types of water manifolds. The production caters for different [...]

Measuring pressure using pressure gauges.
The pressure control in both industrial and environmental hydraulic systems is performed by pressure gauges. There are various types of these around including u-tube, Bourdon, Diaphragm and Piezoelectric. These types are designed to show the pressure difference between the external pipe and the [...]

How safety valves work
Every system is equipped with safety valves. This is because, while in use, the sudden evacuation of a certain amount of fluid may be required, to avoid the prompt increase of pressure inside the pipeline. For incompressible flows, “Bernoulli’s principle” determines the use of safety [...]

Stainless steel hoses for domestic use
In domestic environments, boilers and heating systems, many of you will have surely noticed the presence of metal hoses covered in a protective casing made of rubber or rigid plastic. These hoses are made of stainless steel, a metal alloy made up of Iron, Carbon, Chrome and traces of Nickel. It [...]

The features of shutoff valves
In the world of work, one of the aspects which should always be taken into account is safety: in working environments, it is necessary to protect workers who often find themselves in situations of hypothetical risk, meaning those capable of compromising their health. For this reason, shutoff [...]

Design of gas flow regulation valves.
Success stemming from an idea. This is Gnali Bocia’s enterprising spirit which has brought it over two generations to the design and marketing of gas regulation valves. All the types are controlled and guaranteed by certificates obtained thanks to years of experience and enterprise, which [...]

Gnali Bocia: design of brass fittings
Brass fittings are designed, checked and marketed by Gnali Bocia which guarantees all the features and reject any components having slight defects either on the surface or in their microstructure. The fittings are made of brass, a metal alloy made up of copper and zinc. Brass is used due to [...]

The various types of taps for gas produced
Over time Gnali Bocia has been able to collect experience in design and on the field in order to create many components for gas and fluids. Gas taps stand out amongst these. They are marketed all over Italy in addition to many other countries. The sales catalogue includes many types of gas [...]

The use of pressure reducers with different application fields.
Pressure reducers are extremely versatile components for many fields of application. Gnali Bocia has been able to refine these components in order to adapt them for the use with a range of fluids, each completely different from the other. Both gas and liquid elements such as water flow through [...]
