Planning instructions:
 
The internal space of Nocado ball valves can be rinsed during the CIP process by switching.
 
According to international guidelines the applica- tion of rinsing valves is recommended for the au- tomatic, hygienically unobjectionable CIP-clean- ing. Nocado can provide ball valves with rinsing connections and rinsing valves.
 
Nocado ball valves are used where the full and free passage without change of direction is necess - ary either for the product (e.g. extrusion of but- ter) or for the procedure (e.g. pigging).
 
Nocado produces ball valves with different sizes of drive connections depending on the nominal size. This should be taken into consideration at the order.
