The conclusion is that sooner or later, the rotary valve has to be undertaken a revision and worn out parts have to be replaced. Otherwise the leakage will increase, and the operation and duty of the valve cannot be fulfilled anymore. The OEE (overall equipment effectiveness) will decrease. Gericke has developed its EHDM rotary valve for these applications. The goal is to increase the lifetime, shorten the downtime and make the maintenance very easy and done in place! This is realised by a design which foresees all parts under stress of abrasion as inserts. These parts can easily be exchanged.
The EHDM valves are available in all sizes of the Gericke rotary valve range.
Gericke RotaVal manufactures various types of rotary and diverter valves. For hygienic applications, the extendable HDMF models have proven themselves and can even be equipped with the contact detection device RotaSafe™.
