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.
