1. Design
Diaphragm valve to DIN/EN with flanged ends; shut-off and sealing to atmosphere by spiral-supported diaphragm (DN 65 and above); body with or without lining, position indicator with integrated stem protection. All moving parts are separated from the fluid by the diaphragm. Maintenance-free.

2. Application
Industrial plants, chemical engineering, process engineering, for service water, air, oil, abrasive and aggressive fluids.

Material	EN-GJL 250
Nominal sizes	DN 15 to DN 300
Nominal pressure	PN 10
Permissible operating temperature	-20 to +160°C
Permissible operating pressure	10 bar

1. Reliable sealing ensured by one single sealing element (the diaphragm) which provides hermetic sealing to atmosphere and absolutely tight shut-off.
2. Long service life: The diaphragm support increases valve life and extends the pressure limit of the diaphragm.
3. Balanced diaphragm suspension for increased functional reliability of the diaphragm
4. High resistance to corrosion and abrasion with highquality body materials and linings
5. High level of reliability with thrust bearing minimising the closing torques required
6. Optimised long-term operation: The position indicator with integrated stem protection prevents the ingress of contaminants.
7. High level of reliability: The valve hydraulics without dead volume ensure optimum conditions for high-purity fluids.
8. Quick identification of valve position with clear visual indicator
9. High operating reliability: The stem and all internal operating elements are not in contact with the fluid.
