Greater safety with the shut-off valves of the fuel

Shut-off valve are positive safety devices that protect the system under pressure.

Even the shut-off valves found in the GNALI BOCIA catalogue are realized in CW617N brass, moving from the premise of a body forged and then plated that is capable of ensuring resistance to the action of combustible fluid. Every other component is chosen by lending priority to the product’s duration and reliability.
The task of shut-off valves of the fuel is to avoid damages to the system, caused by excess temperature increases that may result in high pressure peaks; this safety is obtained by interrupting the flow towards the burner.
The safety achieved by using these valves is intrinsic, in that the device is equipped with a positive safety mechanism which sees to the task of closing the passage, both under alert conditions and in the event that the main components of shut-off valves are damaged. The device reset, again from a viewpoint of protection, may only be attained through a manual activation.
The intervention threshold in the event of shut-off valves being affected by emergency is factory-calibrated at 97°C, and makes it possible to protect the system and especially the environments from the possible consequences.
