Safety group with interchangeable safety valve insert and pressure reducing valve, SG160SD
|
|
| |
| 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 non return valve, shutoff
valves, test point, diaphragm type safety valve and pressure reducing valve in one unit. The automatic self opening and closing of the safety valve protects the downstream hot water unit. The non return valve prevents back pressure, backflow and back syphonage of contaminated water. In addition, a balanced seat pressure reducing valve is fitted on the inlet to control the supply pressure to that required for the system. |
