pressure-control valve / flow control / for gas / proportional
F-002A / F-003A / F-003B series Bronkhorst



  • Function:

    pressure-control, flow control

  • Media:

    for gas

  • Other characteristics:


  • Flow rate:

    500 m³/h (17,657 ft³/h)


It is made up of patented indirect acting control valves that is best used for high flow rates, up to 500 m3n/h N2-equivalent. They are utilized to complete Vary-P valve as described above, as pilot valve. Thus, these are also pressure compensated.

The pilot manages the pressure at the back portion of the spring loaded cylinder, of which the front side is subject to the inlet pressure of the main valve. This cylinder provides the power for the main valve. Once the delta-P becomes larger than the spring force, the main valve, will soon open.
