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 [...]

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 [...]

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 [...]

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 [...]

anaerobic sealant for the tightness of threaded brass fittings
The tightness of threaded brass fittings occurs through a conical coupling on the thread, though we must bear in mind that the metal-on-metal coupling is not always enough to seal both liquids and gases. As hinted above, there are methods by now consolidated to seal these threaded brass [...]

Pure copper electric resistances
With power that reaches 3000 W, the electric resistances produced completely in GNALI BOCIA’s Lumezzane factory are versatile, multi-purpose items. The parts that make up the electric resistances are made from prime choice brass and copper that come from a certified supply branch, to give [...]

Waterworks and water pressure reducers
To supply all, even the most peripheral, users and improve the chronic distribution inefficiency of waterworks, distribution companies decided to increase the pressure in the piping, to the disadvantage of the closest users who are obliged to fit water pressure reducers. These water pressure [...]

Water collectors with diameters of 35 mm
Distribution of drinking water has always played an important role in our homes, and modern technology allows us to do this through water collectors made with copper and equipped with taps for the closure of each single branch. This allows for easy maintenance of the single utilities. The [...]

Automatic air exhaust valve for plant performance
An air exhaust valve is a device that is installed upstream to the heating system with respect to the pump for the extraction of air and gases that accumulate and could block the heating fluid. This occurs when the air bubbles obstruct and reduce the passageway of pipes, reducing their [...]
