The resistances are fundamental components for the construction of electrical systems. In fact, resistors (also called resistances) are components placed in the circuits to oppose a specific electrical resistance to the passage of electric current. Although these components represent any users [...]

Hydraulic ball valves represent the most common alternative that can be found within a plumbing system. The main element is constituted by the shutter which has a cylindrical hole: when the valve is open, the cylindrical section is arranged coaxially to the tube allowing the passage of the fluid [...]

The safety valve for the boiler is an essential automatic component for the system. Its main role is to prevent the pressure from rising above an excessively dangerous value, which is about 3 bar for normal wall-mounted boilers: if this value is exceeded, the valve acts automatically going to [...]

We have two types of stainless steel flexible hoses in the section dedicated on the company catalog of our products, and both are made of corrugated stainless steel and can be extended up to twice their original length. For the construction of these stainless steel flexible hoses there is used a [...]

The choice and installation of pressure regulators (or pressure reducers) for a hydraulic system is essential. In fact, the water supplied by the public distribution network is often at higher pressure values than what a domestic user actually needs. The reason for this surplus of pressure is [...]

The systems that carry combustible gases require precise and reliable control systems that can intervene in the event of an anomaly of any kind, avoiding accidents and even serious malfunctions that can compromise the operation of the systems themselves and endanger the people who are found in the [...]

In plumbing systems, many times, it is not possible to use burners or flames to allow the conveyed water to be heated. This prohibition derives from legislative reasons but, above all, from regulations that aim to regulate the health and safety of all the people who live or may be in the [...]

The boilers require the assembly of air vent valves in order to achieve maximum efficiency during their operation, since an abnormal accumulation of gas (released in the system and due to the heating of the fluid) could block the whole system. In fact, air is mainly a double problem: on the one [...]

What is LPG? LPG, an acronym for liquefied petroleum gas, indicates a mixture of low molecular weight hydrocarbons that are in the liquid state thanks to the modest compression required for the change of state which facilitates its transport and storage. It is an odorless gas that is odorized [...]

Water pressure reducers are fundamental components for the construction of systems and for the management of aqueous fluids. In fact, they allow the pressure of the fluid to be reduced, making it suitable for some applications in which it must be used. The experience and precision of Gnali Bocia [...]
