Features & Benefits:

Available in 11 heights, from 10"H to 44"H; and 11 square-flange sizes from 6" to 26".
Valve housing cast in North America; ensures superior strength and solidification of housing's metallurgy.
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; with super-duty series up to 22 PSIG.
Excellent performance in high-temperature applications up to 750°F.
Cast iron housing.
8-vane rotor with beveled tips and sides.
