Rotary valves, like any other component in a conveying, storage or environmental control system, must be tailored to each individual application in order to ensure the best possible results. Not all rotary valves are capable of accommodating the wide range of conveying variables that are prevalent in today's bulk product handling market. When properly installed, and applied with the operating parameters that pertain to a given conveying application, our TaperFlo® IST (tapered bore), series is more than capable of meeting the demands of high pressure, high temperature, and highly abrasive or corrosive applications of these rigorous operating conditions, as well as the simplest gravity feed/discharge application.

To offer the greatest versatility a basic rotary valve must first be constructed in such a way that it will routinely handle both light duty, and by including certain special features, more arduous conveying applications. These special features include abrasive, or corrosive resistant coatings, mechanical seals, special mating flange drilling or other features that meet these parameters effectively, efficiently and economically.

Engineered and manufactured in the United States, and constructed of durable long life ductile iron, the TaperFlo® body bore, with corresponding mild steel, closed end, heavy duty rotor is engineered to offer the system operator the unique ability to very easily adjust the valve's rotor-to-housing radial clearance in order to significantly reduce the negative effects of differential pressure, and guarantee maximum product throughput. Drilled and tapped seal and end cover purge ports, and body vent are standard features supplied on all rotary valves, but can be plugged if not required.

Each of our TaperFlo® rotary valve designs is available in standard ductile iron sizes 6" - 16", stainless steel sizes 6" to 14". A variety of rotor designs to accommodate very wide range of conveying requirements are available. Our registered Duresist^TM rotor constructed of a special stainless steel installed in a ductile iron, Tungsten Carbide coated valve body is incredibly effective at reducing detrimental effects common to abrasive product conveyance, and can very effectively extend valve life well beyond that where more conventional abrasion resistant materials are used.
