1 Low-maintenance designAll moving parts are located outside the fluid.
2 High operating reliabilityThe thrust bearing minimises the closing torques required.
3 Optimised long-term operationThe position indicator with integrated stem protection prevents ingress of contamination.
4 Excellent functional reliabilityIncreased functional reliability of the diaphragm thanks to balanced diaphragm suspension.
5 Optimum hydraulic designThe valve hydraulics without dead volume offers optimum conditions for high-purity fluids.
6 Absolutely reliable sealing to atmosphereA single sealing element, the diaphragm, provides hermetic sealing to the atmosphere and perfectly tight shut-off. The specially enclosed diaphragm1) ensures long service life and high operating reliability.
7 Long service lifeThe diaphragm support increases valve life and extends the pressure limit of the diaphragm.2)
