Safety group with interchangeable safety valve insert, SG160S
|
|
| |
| Type SG160S safety groups 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
valves, test point and diaphragm type safety 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. |
