RA-G

The high capacity valves, type RA-G, are primarily used in one-pipe systems.
All RA-G valves can be combined with all thermostatic sensors in the RA-series.
The RA-G valves are fitted with a grey protective cap. This protective cap must not be used as a manual shut off device. A special manual shut off device is available (code no. 013G3300).
The pressure pin in the gland seal is of chromium steel and works in a lifetime lubricated O-ring. The complete gland seal assembly can be replaced without draining the system.
In order to avoid deposition and corrosion the composition of the hot water must be in accordance with the VDI 2035 Guidelines. It is recommended that formulations containing mineral oil are avoided.
