Safety Groups<br />

21-12<br />

SECURA-Safety group for pressurised hot water storage units up to 200 litres, SG162<br />

SG162 safety groups are controls to DIN 4753 Part 1 and DIN 1988 for the protection of pressurised<br />

hot water storage units with capacities up to 200 litres. They are composite assemblies which integrate<br />

in one unit all necessary safety components, including check valve, shutoff valve, test point and<br />

diaphragm-type safety valve. The safety valve protects the downstream cylinder, pressure vessel etc.<br />

by automatically opening when excess pressure occurs. The check valve prevents back pressure,<br />

backflow and back syphonage of water from the hot water unit.<br />

Approvals TUEV approved, certified to Pressure Equipment Directive 97/23/EG,<br />

Reference No. CE 0035.<br />
