Product informations
Safety valve with INAIL qualified and calibrated diaphragm, which automatically, without the presence of energy other than that of the pressurized fluid, discharges a sufficient amount of fluid to prevent the predetermined safety pressure from being exceeded to protect the heat generator and the system. This valve is used in closed circuit heating systems with a rated output of more than 35 kW and using hot water with a temperature below 110°C; causes of valve tripping can be:
- elevation of the operating fluid temperature above the preset maximum value resulting in uncompensated expansion
- insufficient dimensioning of the expansion tank
- excessive circuit filling pressure
