Axial Check Valves, are also called Spring Check Valves or Sprung Disc Check Valves because, as the disk moves from the seat, it compresses a spring mounted in line with the disc.

They fall broadly into two categories
Guided Axial Check Valves where the disc is connected to a shaft which runs within a guide.
Unguided Axial Check Valves, a less complicated design without a shaft, this type allows a shorter installed length and so most are wafer pattern.

Because of the sprung design both types are suitable for mounting in any orientation, however, care must be taken when selecting for downward vertical forward flow.

All our ranges of Axial Check Valves are simple, robust designs capable of operating over a wide range of conditions.

We carry stocks in the UK backed up by huge stocks at head office in France.
