Safety groups of this type are used to protect pressurised water heaters according to the requirements
of DIN 4753, Part 1, DIN 1988 and DIN EN1488.
They are compact appliances which incorporate all the necessary safety devices such as check valve,
shutoff valve, test point, diaphragm type safety valve and pressure reducing valve in one unit. The
safety valve protects the downstream cylinder, pressure vessel etc. by automatically opening when
excess pressure occurs. The check valve prevents back pressure, backflow and back syphonage of
water from the hot water unit. In addition, a balanced seat pressure reducing valve is fitted on the inlet
to control the supply pressure to that required for the system.
