Blow-Through Rotary Valve

The Blow-Through Rotary Valve is designed for feeding loose products into high-pressure pneumatic conveying systems. Maximum positive pressure up to 1,0 bar.

 

 

 

 

 

Construction

Basic elements of the Blow-Through Rotary Valve are:

  • cast iron bod with rectangular inlet and modeled channel in bottom part,
  • cast iron rotor (without side walls) installed inside the body,
  • side covers with pressure bearings and sealing rings; inside the covers there is also installed connector allowing supply of air assuring additional sealing,
  • bearing covers
  • as an option drive consisting of moto-reducer, chain transmission with cover fastening plate


Operation principle

Product is directed to inlet of the airlock and as a result of rotor's revolutions it is evenly fed to the outlet, simultaneous cutting off the air low from the pneumatic conveying systems.
