SG160S
Safety group
with interchangeable safety valve insert
Product specification sheet
Application
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 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.
Special Features
• DIN/DVGW-approved
• Fully approved for noise level protection to class 1
• Replacement insert tested to TRD 721
• Easy venting
• Meets KTW recommendations for potable water
Construction
The safety group comprises:
• Housing with G
• Connections (versions AA, AB and AC)
• Shutoff valves

SG160S Safety group
Method of Operation
Safety groups of this type combine check valve, shutoff valves,
test point and diaphragm type safety valves in one appliance.
Flow first passes through the check valve and this flow holds the
valve disc in the open position against the force of a spring.
The downstream safety valve is a direct operating safety valve.
That is, the opening force operates against the force of a spring.
The shutoff valves enable the check valve to be checked and
serviced.
