Safety valves are necessary for your own protection

It is always necessary to install a safety valve, which can protect the system from excessive pressure due to malfunction, to the output of a hot water generator. This device takes care of lowering the excess pressure and of bringing back the internal plant pressure to acceptable values.
This safety valve is constructed and approved in accordance with the provisions of Directive 97/23/EC, also known as PED, and it is calibrated by the use of certificated databases. The response pressure is normally set in a range from 6 to 10 bar, but it is also possible to set it for different pressures on request. The maximum working temperature can reach 95 ° C.
Its construction is carried out starting from a CW617N brass blank, worked on latest generation numerical control machines. Thanks to modern processing, GNALI BOCIA can deliver a reliable, safe and long-lasting safety valve to the market.
The safety valve version for water heaters equipped with a manual control lever is also very useful, this enables the user to voluntarily intervene to relieve excess pressure or in case of the need to empty part of the plant.
The design and construction are made in order to avoid the annoying dripping problem, which could create problems as the discharge takes place freely and may cause the flooding of the premises.
