For connections to the distribution network and to the meter it is necessary to use meter valves which guarantee the interception of the fuel fluid and the isolation of the system from the network.
Made with a closing ball, these meter valves conform to EN331 which defines all criteria for [...]


A fitter certainly has many advantages when choosing brass manifolds for implementing systems, whether they are sanitary or heating. The use of these items ensures assembly is more economical as the use of less rigid pipes speeds up the installation phase. The reliability of the system is [...]

The more the user requirements, the broader the proposals by the GNALI BOCIA company in the field of gas taps, which you can find installed on stoves and burners, whether civil, industrial or camping and outdoor applications.
Starting from the needle version, passing through the cone ones to [...]

When you need compact solutions for connecting multiple users to a single tank in gas fired plants, the best solution is to use mini control units; we can find them in various models in the special catalogue.
GNALI BOCIA has always tried to meet the needs of the end customer in terms of ease [...]

Impurities present in heating installation fluids, generally water, can lead to generating dissolved gases which tend to accumulate in the highest points of the circuit, including radiators. Air relief valves placed on radiators allow discharging air accumulation outside the system as this can [...]

We find electrical resistances for heating the system fluid both in domestic and industrial systems, be they part of pressurised circuits or free. They are produced by inserting a filament inside a copper tube, when this is crossed by the current it produces heat. This is separated from the [...]

When we talk of system safety, we immediately think of a fail-safe device such as the fuel shut-off valve which interrupts the fuel flow to the boiler when a higher temperature than the pre-set safety one is registered on exit. Calibration of a complex mechanism such as the fuel shut-off valve [...]

The GNALI BOCIA catalogue offers non-extensible model FL286 stainless steel flexible tubes whose length of two metres maximum corresponds perfectly to the new EN14800 regulation. They are made from a corrugated pipe of austenitic stainless material which ensures the stainless steel flexible [...]

Regulating gas distribution pressure may be done through locally installed pressure regulators, particularly for low and small flow values. However, when the pressure and flow values are much higher we can use balanced pressure regulators. The models produced by GNALI BOCIA are spring loaded [...]

System parts adjacent to the meter, both upstream and downstream, are extremely important in the field of Natural Gas distribution. Meter valves enable intercepting gaseous fluids both upstream and downstream of the metering device and must ensure perfect sealing. Produced in chrome-plated [...]
