Type 905 H
For the protection of heating systems according to DIN 4751 and DIN EN 12828 to prevent damage due to excess pressure during filling.
The filling valve is installed in the feed line. The filling of the system is automatically controlled by the built-in pressure reducer. The filling valve shuts off when the set pressure is reached and thus prevents overfilling.
For use in Germany, the hose connection has to be disconnected from the filling valve after filling of the plant. For use outside Germany, this valve can be supplied with a male union joint G 1/2” on the inlet side. Please inform us when ordering which kind of connection you require.
