Butterfly valve for burner regulation
FVA/FVS series Hauck

  • butterfly valve for burner regulation FVA/FVS series Hauck
Operating conditions encountered in the automatic controlling of gas and air flows often require valves with an adjustable flow curve which can be altered at various points of opening to obtain the desired amount of flow. Such flexibility is not obtainable with ordinary adjustable port valves having a fixed height of port opening over the entire range of operation.

With Hauck adjustable Flow Valves, the flow rate can be easily changed at any of the 10 or more adjusting points provided. Therefore, the valve flow curve can be characterized to suit different constants in pressure, flow suction, or discharge resistance occuring at the minimum, maximum or in-between capacities. Infinite flexibility of flow characteristics is thus available. These valves are designed for use as control valves and they should not be used as shutoff valves.
