Quick-Clean Aerolock Rotary Valve Features

Housing and end plates
The housing and end plates are machined from castings and are made of wear iron or chrome-plated wear iron. The shear action inlet reduces stress on the rotor and housing. They have round or square flanges and can have custom coatings applied to interior surfaces for demanding applications.

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 wear life. Undesirable movement along the longitudinal axis is prevented by the collar which locks the bearings to the shaft. A grease fitting is provided for ease of maintenance.

Bearings - drive end
Tapered roller bearings used in a preloaded carriage provide precise shaft alignment. The bearing carriage is equipped with grease fittings, making it easy to renew lubrication.

Seals

• T3 seal
  The general purpose T3 seal is used on both ends of the rotor shaft. The assembly is comprised of a Teflon® collar anchored to the shaft and two steelcased quad ring seals which fit over the Teflon collar. The seals remain stationary while the Teflon collar rotates with the shaft. The Teflon’s slick surface allows quad rings to operate in dry mode with good service life.
• Packing gland seal
  The packing gland seal uses Teflon impregnated yarn. As wear occurs, the seal’s effectiveness can be increased by tightening the collar.
• Air purge seal
  The air purge seal is available for severe service applications. Plant air is introduced through end plates and the air diffuser ring. This provides a zone of higher pressure outside the seals than inside the Aerolock.
• G5 seal 
  The G5 seal is for high service applications and includes a quad ring Buna-N seal on a stainless steel insert.

Gaskets
The gaskets provide a positive seal between Aerolock 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.

Rotors
The rotors are engineered for rugged applications. The shafts are sized for torsion and bending loads far above standard drive horsepower requirements. Ten blades maintain a minimum three-blade labyrinth seal to minimize air leakage. A choice of rotors allows the quick-clean rotary valve to be tailored to your application. The hubbed rotor, when used in conjunction with air purge seals, provides longer shaft seal life and less end plate wear, especially in applications with mildly abrasive materials. The open-end rotor with relieved tips is used to reduce drag on materials that tend to build up on the housing and end plates.

Simple Disassembly

	1. The T-bolts unscrew by hand, and the hub cap is easily removed
2. Using a hand-held wrench, the exposed end of the rotor shaft is turned clockwise approximately eight turns, disengaging the rotor from the drive end of the shaft.	3. With end plate separated from the housing, the end plate/rotor assembly is easily removed.
4. Without disturbing the seals or bearings, the rotor, end plates, and housing chamber are exposed for easy cleaning.
