Safety group Securfix NG 4807 18 litres 6 bar 24570

Compact safety group for reliable protection against overpressure in closed DHW heating systems. 

The flow-through diaphragm expansion vessel with nitrogen filling ensures optimum function by keeping the inlet pressure stable over a longer period of time. The diaphragm safety valve has a drain funnel that reliably drains off any escaping water. A three-way ball valve enables the expansion vessel to be shut off easily and drained quickly for maintenance work.
The integrated check valve is replaceable and equipped with a test device.

Thanks to the sturdy suspension frame with snap-in mechanism, the safety unit can be mounted quickly and securely on the wall.
