6 / 16 in Pneumatic Conveying

MD Series

Rotary Valve for Metering, Feeding and Airlock Applications

For long-term savings, ACS designed this valve to reduce total lifecycle maintenance requirements. The MD Series housings are cast in North America and CNC-machined to precise tolerances, eliminating axial shaft movement, seal leakage, and shortened bearing life.

Features & Benefits:

Available in 7 heights, from 7 3/8"H to 23 1/2"H; and 7 flange diameters from 4" to 16".
Cast-iron valve housing with superior metallurgy provides strength and durability for a longer overall lifespan.
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.
8-vane rotor with beveled tips and sides.
