Advantages
– Reliable sealing ensured by one single sealing element (the diaphragm), which provides hermetic sealing to atmosphere and absolutely tight shut-off. The specially enclosed diaphragm ensures long service life and high operating reliability.
– Increased functional reliability of the diaphragm thanks to balanced diaphragm suspension
– Maintenance-free as all moving parts are separated from the fluid by the diaphragm.
– High level of reliability as the thrust bearing minimises the closing torques required.
– Optimised long-term operation as the position indicator with integrated stem protection prevents the ingress of contaminants.
– High level of reliability as the valve hydraulics without dead volume ensure optimum conditions for high-purity fluids.
– Long service life as the diaphragm support increases valve life and extends the pressure limit of the diaphragm.
– Both the SISTOMaXX diaphragm material and the body material 1.4409 and coating material polyamide (Rilsan) meet the recommendations of the German Environment Agency (Elastomer Guideline) and DVGW Worksheet W270. -
