Designed for normal to heavy industrial service, the Heavy-Duty Aerolock™ rotary valve will perform at up to 1.0 bar [15 PSI] pressure differential. The round or square inlet/outlet configurations of this airlock rotary valve allow maximum product flow while maintaining an optimum air seal.

HD Aerolock Rotary Valve Features
The gaskets provide a positive seal between Aerolock rotary valve flanges and components directly above and below. They are made of 6 mm [.25 in] thick white neoprene and are comprised of sections that interlock to ensure they stay in place and provide an airtight seal.
Bearings - thrust end
The radial-thrust, tapered roller bearing assembly is preloaded to provide minimum rotor deflection. This results in close rotor clearance to maximize rotary valve wear life.
Bearings - drive end
The radial ball bearing assembly provides firm shaft support on the rotary valve drive end and allows expansion and contraction due to temperature changes along the longitudinal axis.
Housing and endplates
The housing and end plates are machined from castings and are made of wear iron, chrome-plated wear iron, or stainless steel. They have round or square flanges, and the shear action inlet reduces stress on the rotary valve housing and rotor.
The eight-blade, open end rotor maintains a minimum two-blade labyrinth seal to minimize rotary valve air leakage. Relieved tips reduce rotor drag on materials that tend to build up on housing, and the design reduces pressure points that cause extrusion of materials molded or shaped by pressure. Rotors can be equipped with flat tips for use with cereal products or relieved tips for materials that would normally form skins or thin sheets between the end plates and hub area. Materials of construction include steel and stainless steel.
