The relief system in gas safety valves
The gas management systems are designed to maximise the efficiency of the plant in normal operating conditions or when at a standstill: it is always best to work at constant operating conditions as much as possible and this can be guaranteed by components such as gas safety valves. There are two [...]

The operation of shut-off valves
Boilers are generally equipped with a system able to monitor the temperature of the liquid (generally water) flowing inside the circulation system. It is essential to monitor the maximum and minimum temperature of the liquid in order to ensure a suitable temperature. The temperature control [...]

Safety guaranteed by Gnali Bocia gas taps
Strict standards are in place to ensure safety to all people close to possible dangerous sources such as LPG, methane and other gases. The standards must guarantee that the prevention and protection measures are sufficient to avoid any accident by drastically lowering the risk threshold. In [...]

Series of requirements for hydraulic valves
To ensure the safe use of the hydraulic valves, the engineers of Gnali Bocia, a leading company in the sector of connecting elements, have to meet the design demands of the components to be sized. The process starts with selection of materials, which already implies a first selection of the [...]

Thread requirements on water manifolds
To guarantee uniformity among products from different manufacturers, Gnali Bocia adopts a series of standards that define, as well as the essential safety and environment requirements, also the dimensions and tolerances required. One category that envisages the use of standards is that of [...]

Gas outflow from high pressure reducers
High pressure reducers are made of brass, offering high resistance and sealing efficiency in consideration of the maximum pressures acting inside this component. Brass guarantees optimal load resistance in high pressure reducers and in combination with safety systems for the release of excess [...]

The UNI-CIG 7129 standard and flexible water tubes
In domestic and industrial applications, when two or more systems need to be connected in series to operate with water or other fluids, special flexible tubes are used, designed to be used in a wide range of operating conditions. To enable the marketing of these tubes worldwide, Gnali Bocia has [...]

Pressure management in mini control units
LPG systems are now used on a great number of ‘green’ cars, as they fuel the engine throughout journeys, reducing CO2 emissions and other gases generated from combustion of petrol. In order to manage the LPG system, a number of primary and secondary components are used, designed to manage [...]

Brass fittings from Gnali Bocia
Brass is an alloy of Zinc and Copper, frequently used for fittings destined for the hydraulic industry. Products designed and marketed by Gnali Bocia include both components for LPG and other gases, and components for use with incompressible fluids. The exclusive feature of Brass fittings lies [...]

Shut-off valves prevent the risk of cavitation
In the sectors using valves, critical situations very often occur that can damage the valves, at time very seriously. One of these conditions is called cavitation. This is responsible for the formation of air bubbles inside the valves, which then implode producing a characteristic noise. The [...]
