The automatic filling valve keeps steady the pressure of the water of the waterworks on pre-fixed values. The filter installed at the lower part of the automatic filling valve avoids all the impurities to flow into the same automatic filling valve. The incorporated check valve avoids the return of the water of the heating system into the main pipe. The adjusting chamber allows a reduced steady pressure at the outlet, even if, at the inlet, the pressure can be changed. In emergency, the water flow can be closed completely through the handwheel.
