Brass manifolds complementary to hydraulic fittings
For the sanitary distribution or for the heating systems, the choice often falls on the brass manifolds, devices that combine the practicality of the connection to the modularity, but above all to a considerable saving of space. And perhaps this last feature is the one that makes the choice in [...]

Air vent valve controlled by a float
We know that the air vent valve is the cure to eliminate the accumulations of air from the systems that besides generating the well-known noise in the pipes, can generate obstructions in the pipes or worse cavitation in the pumps and lastly also corrosion phenomena . The first step to reduce [...]

Ball gas valves for the interception
A section of our catalogs is dedicated to ball gas valves, dedicated to the fuel interception either on the system along the pipes or in the terminal position before the user appliances. In addition to the classic full-pass model with lever, there are also angular models of gas valves with a [...]

Electrical resistances for heating water
The electrical resistances for heating are useful in all those occasions when it is not possible to heat water or fluids through the use of a flame for safety or security reasons, or simply the presence of a fuel distribution network. Their purpose is to bring the fluid to a useful temperature [...]

Industrial pressure regulators for gas
The range of pressure regulators FG100 and FGB100 is used in applications that require very high flow rates, such as in the industrial or commercial sector that require at the same time a very high response speed. This is allowed by the way in which these pressure regulators are designed and [...]

Hydraulic fittings in brass
The hydraulic fittings are just one of the leading products that are manufactured at Lumezzane in the establishments of GNALI BOCIA, starting from hot-pressed brass blanks and subsequently machined on CNC transfer machines of the latest generation. Hydraulic fittings are complementary products [...]

Mini power packs with one or two stage reducers
The mini power packs produced by GNALI BOCIA serve for coupling at any moment two or more cylinders of gas , usually LPG, for powering devices such as cookers, refrigerators, boilers or hot water kettles, exploiting their compactness. In fact one of the sectors where mini power packs are used is [...]

Use the manifolds for heating for better distribution
One of the advantages that derive from the use of manifolds for heating is surely due to the fact that the pressure drop on the various ramifications are reduced compared to other types of installation, but also the heat distribution in the system is much more uniform and consequently the yield [...]

Safety valve and assembly onto the water heater
The safety valve is an essential component to ensure the safety of persons and installations, when the latter are heated at high temperature through water heaters and boilers that might give rise to such elevated pressure values as to cause their explosion. To avoid this, the dedicated section [...]

Tricks to install water hoses
When installing kitchens and boilers, the connection of the device to the plumbing and heating distribution system may only be done with water hoses, made of stainless steel and corrugated to enable their extension up to the desired size, or to make them go through a complex path. Installing [...]
