RAF 13 is used to control filling of water reservoirs and tanks. RAF 13 is a non-modulating service valve, operating as an on/off valve. The RAF 13 is activated by line pressure and controls by a float pilot.
The valve opens at a low preset water level and closes at a high preset water level. Therefore, there is no need for energy other than line pressure.
The RAF 13 allows filling and draining of a reservoir or a water tank in a level range that can be easily changed.
The RAF 13 stays in its last position (fully open or fully close) as long as the water level is in between minimum and maximum preset levels.
Maximal Nominal Pressure: 16 bar.
