Design 
Flanged end diaphragm valve; shut-off and sealing to atmosphere by completely enclosed spiral-supported diaphragm. Body with or without lining. Position indicator with integrated stem protection. All moving parts are separated from the fluid by the diaphragm. Maintenance-free. 
Application 
In building services, industrial plants and power stations; suitable for drinking water, service water, air, oil, technical gases, from fluids handled in the food and beverages industry to abrasive and aggressive products in chemical and process engineering.
