The AL and BL Dairy valves are available in 6 sizes, covering a capacity range from approximately 2,5 to 58 litre per revolution at 100% filling. The BXL valves are available in 4 sizes representing a capacity range of the rotor from 5,5-34 litre per revolution at 100% filling. The AXL-BXL size corresponds with the dimension of the inlet flange.
The body and end covers are made from AISI 316 stainless steel (DIN 1.4408). The rotor is made from AISI 316L stainless steel (DIN 1.4404). For special applications internal and external mirror polishing of the valve is possible.
For the BL-BXL valves tri clamp connections are also available.
The shaft sealing is by means of gland packing or air purge.
