RIEGER Overflow valves E8 are a combination of angle valves and relief valves. Unlike an overflow valve, this valve opens on request up to 100% stroke like shut-off valve. It is possible to seal the overflow valves.
One possible application is the protection of forced-feed pumps e.g. peristaltic pumps.
The overflow valve E8 is suitable for all liquid pumpable media.
Overflow valves are no safety valves.
For this purpose we recommend the TÜV certified safety valve type SH .
