Válvulas rotatorias resistentes a la abrasión
Prater Abrasion Resistant Rotary Airlock Valve is the preferred choice for highly abrasive or corrosive products. The rotary airlock’s ceramic lined cast iron housing achieves better performance than airlocks made of solely of cast iron, stainless steel, or Ni-hard. The thick-wear layers of alumina ceramic coating throughout the airlock maintains the rotary valve’s precision tolerances and provides long wear life. Other features include an over-sized mounting flange, Heavy-duty outboard bearings, self-adjusting packing glands (a Prater Exclusive), and pre-drilled end plates for air purge.
the Ceramic Series Rotary Airlock ensures up to +/- 12 PSI pressure differential and up to 300°F. Constructed from either cast iron or stainless steel, the Ceramic Series valve is fully equipped with eight-blade rotors with your choice of speed and square sizes of 6, 8, 10, 12, 14 and 16 inches. Its heavy cast iron houses an over-sized mounting flange, heavy-duty outboard bearings, self-adjusting packing glands (a Prater exclusive) and pre-drilled end plates for superior air purge. Additionally, ceramic options include ceramic-lined end plates, ceramic-lined rotors and tungsten carbide throat. Options include ceramic lined end plates, ceramic lined rotors, and tungsten carbide throat.
Prater ceramic airlocks reduce maintenance costs and help avoid losses in production, all the while achieving higher efficiency by holding our tighter tolerances longer. When heavy-duty just is not enough, our Ceramic Series is the proven solution to rotary airlocks that wear out in high-abrasive applications.
