概况介绍
Rotary Valve MD 1820
The Maximum-Duty (MD) 1820 AerolockTM is one of our largest rotary valves and is designed for high volume service. The MD 1 820 is commonly used with some of the most challenging materials including minerals, chemicals, fillers, food ingredients, filled pellets,PVC compound and diatomaceous earth. The MD 1 820 is engineered for heavy to severe industrial service with pressure differentials up to 1.4 bar(g) [20 psi(g)] and/or temperatures of 121 C [250° F].The ability to withstand severe shock loads and elevated temperatures make the MD 1820 Aerolock a“true maximum duty" performer.

The MD 1820 has a ten-blade, rotor that maintains a minimum three-blade labyrinth seal to minimize air leakage. The ten-blade rotor is available with flat or relieved tips in several rotor choices. The MD 1820 a single radial ball bearing on the drive side and two tapered roller bearings on the thrust side.
