  Auto filling valve

  Overview:

  The automatic filling unit is a device consisting of a pressure-reducing valve, stainless steel filter, shut-off valve, and a check valve. With a visual design, installed on the water inlet piping in sealed heating systems, and its main function is to maintain the pressure of the system stable at a set value, automatically filling up with water as required.

  With a visual design, installed on the water inlet piping in sealed heating systems, and its main function is to maintain the pressure of the system stable at a set value, automatically filling up with water as required.

   

  This product has the characteristic of being pre-adjusting, which means that it can be adjusted at the required pressure value before the system charging phase.

  After installation, during the filling or topping-off phase, the water feed will stop when the set pressure is reached.

   

  Built-in shut-off valve and check valve.

   

  A large diaphragm-seat seal working surface, bigger 40% more than the general product, guarantees greater precision and sensitivity to maintain its operating characteristics unchanged over time.

  Mounting instruction:

  The filling unit can be installed in either horizontal or vertical positions. It is, however, vital that the unit is not installed upside down. The direction arrow is the inlet.
  AF0520 unit, 0.2 bar pressure will be added by screwing the knob on the top one circle in the clockwise direction, conversely, the pressure reduced.
  AF0522 unit, no need to install pressure meter, just adjust the pressure at a set value before filling.

  Auto filling unit, the outlet pressure should be over 0.3bar than the static pressure, and the setting pressure should be less than the filling pressure or it can not work normally. It is normally installed at the water backflow part.
  Automatically filling, until it reaches the required valve.
  When filling water, the shut-off valve can be closed by hand.
  The valve disk can be cleaned or changed.

• The automatic filling valve is a device consisting of a pressure reducing valve with compensating seat, visual system pressure setting indicator, an inlet filter, anti-scale internal parts, a shut-off valve (round knob on bottom), and a check valve. And installed generally onto supplying pipe in sealed circulating heating or refrigerating system, it maintains the pressure of the system stable at a set value and prevent water-back flow happening, or automatically fills up water into supplying, device or end-user device when pressure differential happens between upstream and downstream
