Rotary Airlock Valves
Diverter Valve
Double Dump Valves
Rotary Valves
Diverter Valves
Double Dump Valves
  • Feeder applications with no pressure, used purely to feed product from a bin or hopper
  • Filter applications e.g. cyclones, baghouses and various collectors where fine dust must be collected whilst maintaining an air seal.
  • Pneumatic conveying applications where feeding material into a system against pressure or vacuum.
  • Used in the pneumatic conveying industry
  • Reroute powder, pellets or granules from one discharge to another.
  • Used for low-pressure feeding applications on fibrous, large particle and/or very abrasive products
  • Used where rotary airlocks would typically jam and/or suffer intolerable wear.

Butterfly Valves
Gate Valves
Butterfly Valves
  • Heavy duty valves with cast bodies, knife gate, stuffing box with packing and oversized air cylinders. 
  • ASA 150 lb bolt hole pattern.
  • Options include resilient seat for sealing against pressure or vacuum; solenoid valves and proximity sensors. 
  • The knife gate is also available with hand crank actuator.
  • Consists of a circular disc with its pivot axis at right angles to the direction material is flowing.
  • Made up of a body, seat, disc, stem, and actuator.
  • Each component part is available in a variety of materials called “trim features.”
  • Properly combining trim features to address material handled and environment is important in selecting the correct model valve for its intended service.
