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.   Guided Axial Check Valves Threaded A simple little valve with Brass body, Nitrile & Nylon Disk and Stainless Spring.  Rated 12 Bar at DN10 (3/8") and 16 Bar on the other sizes, the ends are screwed BSP Parallel.
