Diverter Valves - Air Flow

Diverter Valves and Automatic Diverter Valves

Diverter valves are primarily used by customers wanting to …well…divert material or air between two different locations.

Automatic Diverter Valve

For example, the wood processing industry has often used them to direct collected wood dust or chips that is being blown into one of two trucks, When one truck is full the valve is shifted and the material is blown into the other. Likewise the paper industry also uses them to ‘pull’ paper trim between two different locations.
While diverting material could be accomplished using a branch and a series of gates or auto gates, the diverter valve is much more efficient and since it is manufactured using much heavier materials- (1/4″ steel body) a diverter valve is able to better sustain multiple and rapid transitions with heavy material that can cause problems with gates.
When you order a Diverter Valve for your dust collection or other ducting system from US Duct, you are assured of getting a heavy duty valve with a tight sealing door that is built to last for years. An inspection door allows you to clean out the valve (helpful for applications involving colored plastics) or as needed to replace the rubber seal on the door.

The valves are available in manual or automatic. US Duct’s Automatic Diverter Valves are pneumatically operated and electrically controlled. The pneumatic cylinder requires 90 psi to operate but uses very little volume. Duel solenoids activate the cylinder. The solenoids are activated by virtually any electrical signal—12/24 V, AC/DC, or 110/220 line voltage. These solenoids operate off of milliamps and therefore require only minimal wiring. The valve is powered in both directions to deflect the air through the primary or secondary exit.
