RITAG wafer type swing check valves require almost no maintenance. The seat gasket can be made of metal or elastomer ( NBR, EPDM, FKM, PTFE). The vavle is self-centering and protected. ZRK1 and ZRK3 are among the best-selling check valves.
Wafer type swing check valves can be installed between flanges in vertical pipelines (figure 1) or in horizontal pipelines (figure 2).
The main areas of application are in industrial pipelines for gaseous and liquid media.
