Applications

Kice VPOT airlocks are cast-iron, outboard-bearing valves that incorporate a blow-through style connection to a pneumatic conveying line. They are made for situations where height considerations or special product characteristics come into play.

Custom features

  • Trailing edges relieved (TER) is a process that machines the back side of the rotor tips and sides to a 45-degree angle, reducing the surface area of the tip and lessening the chance of an airlock binding when handling sticky products.
  • Inlet plows are standard on Kice cast-iron valves. This creates a scissor action as each rotor blade enters the housing, reducing the likelihood that a piece of product will bind an airlock in the nip point.
  • Kice rotors on all valves are cast iron and precision-machined to match each valve body for efficient performance and long life. Rotors have open ends and are full depth. Eight blades come standard.
  • Bolt-on rotor tips are available in an assortment of different materials depending on the material being handled. AR steel tips can be used for abrasive material. Flexible urethane tips can be used for fibrous materials that may choke a valve.
  • Special clearances between the rotor blades and the housing are engineered for specific temperature and product concerns.
  • Square and round inlets and outlets are available on most Kice airlock models.
  • Coating and plating such as hard chrome, nickel and Nedox can be applied to machined surfaces inside Kice airlocks to meet special product requirements.
  • Bolt-on pans are used with drop-through style airlocks that feed pneumatic conveying lines.
  • Air purge seals are available on outboard-bearing airlocks to help keep product away from bearings.
  • Kice surge hoppers are used on the inlets of airlocks that feed pneumatic conveying lines. They provide a clear path for airlock bypass air to leave the product stream relatively slowly without carrying product with it. Surge hoppers are available as round or square units depending on the application.
  • Inlet shunts are used to keep product out of the nip point, the area where the rotor enters the housing.
  • Materials of construction include cast iron, fabricated steel or stainless steel.
