RESILIENT SEAT SEAT SWING CHECK VALVE, PN10/16
Free RH side, brass-bushings, EN 558-48, SS shaft, EPDM, A2 bolts, 250µm blue EP coating
Resilient seat swing check valve, for drinking water and neutral liquids incl. treated waste water free of solids and fibrous impurities to max. 70°C
AVK series 41 swing check valves come with both metal and resilient seats. Installed in pumping applications to prevent back flow they can be used for drinking water as well as waste water. The disc is connected to the shaft via a flexible bush that allows disc and valve seat to adjust exactly. All interior parts are stainless steel or coated with drinking water approved epoxy or EPDM. The series 41 valves are available with either enclosed shaft end or protruding shaft end where a lever with a weight or a spring can be fitted to mitigate pressure surges.| Variant 41/60-003 | |
