The MZC valves are easily detachable in a few minutes. The AL Dairy valves are available in 6 sizes, covering a capacity range from approximately 2.5 to 58 liter per revolution at 100% filling. The AXL valves are available in 4 sizes from 200-350, capacity range of the rotor from 5.5-34 liter per revolution at 100% filling. The AXL size corresponds with the dimension of the inlet flange.
The body and end covers are constructed from AISI 316 stainless steel (DIN 1.4408). The rotor is manufactured from AISI 316L stainless steel (DIN 1.4404). For special applications, internal and external mirror polishing of the valve is possible. The shaft sealing is by means of gland packing or air purge. The standard models are suitable for temperatures up to 80 °C and a pressure up to 2 bar g. Flameproof and explosion shock-resistant versions up to 10 bar g are also available.
