Features & Benefits:

Stainless steel valve housing, cast in North America, ensures superior housing solidification and metallurgy; eliminates pits and dimples where contaminants could accumulate.
Product contact surfaces of the housing, and all rotor surfaces, are a No. 4 finish.
Tool-less, single-step access to rotor and internal surfaces; simplifying cleaning, validation, and inspection.
RotorRail™ feature maintains rotor and endplate alignment during dis-assembly; ensures fast and accurate rotor and endplate re-alignment during re-assembly.
Available in 7 heights, from 7 3/8" to 23"; and 7 flange inside diameters from 4" to 15".
CNC-machined components and housing provide precision tolerances; eliminates axial shaft movement, extends maintenance cycles.
Outboard bearing design protects bearings in high-temperature and high-PSIG applications; removes bearings from direct path of damaging contaminants.
Easily manages pressure differentials up to 15 PSIG.
Excellent performance in high-temperature applications up to 500°F.
8-vane rotor with beveled tips and sides.
Direct-drive motor package.
