The safety valves designed and produced according to PED guidelines
The PED 2014/68 / EU directive is a directive drawn up and issued by the European Union Parliament on the design, construction and installation of components and pressure devices to ensure the safety of systems and the persons in contact. It does not represent the first legislation in the field [...]

The UNI-CIG 7129 standard and flexible water tubes
In the design and construction of water systems, flexible hoses for water are very often used, i.e. pipes that can be adapted to different regimes and configurations. Generally these pipes must comply with the UNI CIG 7129 standard for marketing all over the world: Gnali Bocia, in fact, has [...]

Industrial electrical resistors combined with effective thermostats
Industrial electrical resistors are a component of considerable importance for the development of heat within industrial systems. Their study and design must be carried out accurately in order to ensure effective operation and minimize the losses that may develop within the circuit in which they [...]

Use the automatic air vents on heat sinks.
To improve the efficiency and operation of radiators and heaters, it is necessary to have air vent valves available. They can be mainly of two types: - Manual air vent valves: present on most long-standing radiators, they require human intervention by unscrewing a valve. - Automatic air vent [...]

The UNI-IGC 7129 still allows the use of extendable flexible water pipes.
The UNI-CIG 7129 standard represents the reference standard for the production and marketing of extendable and flexible pipes for water. This type of pipes is a valid alternative widely used in applications that require extendable or difficult to position and put into operation without the [...]

Boiler safety valves do not always leak because they are faulty
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 [...]
