
Pressure safety valve factory is maunted and must be of nominal diameter of 1/2 inch
calibrated to a maximum of 3 bars.
This security element which belongs to the group of pressure limiters must be of such
construction to withstand short-term overdrafts and temperatures and pressure as well as
the content in the liquid glycol for heating.
This safety element must be subjected to periodic re-calibration , of which the investor,
i.e. the user of the boiler must have valid documentation.

Recommend and install a pressure gauge (Figure 4) the hydraulic installation.

Safety valve must be mounted on the highest point directly to the boiler and the boiler
without any pipeline or any other elements in between. For this purpose there is a
specially designed connector (see picture). Any reduction in the diameter of the
connector during servicing and assembly of a new safety valve is strictly forbidden.

Drain or exhaust of the safety valves must be of pipes with a diameter at least equal to the
nominal diameter of the outlet part of the valve. You are allowed to use up its production
of an arc of radius r> 3d.

The safety valve must have a nameplate and the following information on it:
- Name of manufacture;
- Designation of type of safety valve / year of testing;
- Nominal flow rate;
