Special advantages:

  • Streamlined, smooth passage with minimum directional change of product
  • Particularly advantageous for fatty products
  • Prevents the formation of deposits of heat-sensitive products
  • Hose switch can be used at pressures of up to 3 bar absolute

Preferred applications:

AZO hose switch was developed for use in pneumatic pressure conveying systems. Due to their design standard diverter valves with rotary elements cause a directional change of the delivery flow, resulting in a larger pressure drop. With the AZO hose switch a solution has been developed that makes it possible to achieve minimum directional change of product.

Functional principle:

Hose switches are used to switch product flow in conveying systems. Depending on the delivery direction, it is possible to direct product coming from two lines into one delivery line or vice versa. The non-connected line is sealed off tight.
After a pneumatic cylinder has precisely aligned the slide plate with attached hose connector flush with the mating connection piece, a hollow chamber seal per connector is inflated with compressed air. Due to this change in shape, the seals snuggle up to the slide plate, thus sealing the gap between the slide plate and connector housing. The air pressure is measured by a pressure switch with two switching points, which regulate seal inflation and product delivery. The end position of the slide plate is precisely aligned by adjustment facilities on the slide plate mount and by an adjustable stop on the cylinder head. This ingenious design makes it easy to disassemble the slide valve and clean the hose switch.
