SPECIAL VALVES

SAMPLE OF SOME VARIATIONS

  • Revolutionary option to traditional rotary valve—impellor valve, a low profile lightweight multi-vane butterfly valve. St st seat & vane ensures most applications can be  met
  • In-line lump crusher, ideal for process lines where product has tendency to agglomerate which is broken back down to powder when passing through this valve. Host of material options & throughputs
  • Blow line diverter valve—ideal for pneumatic conveying lines with multiple destinations. Generally supplied as twin route outlets, although other variants are available
  • Heavy duty flip/flop valve, another alternative to traditional rotary valves as maintains process pressure during operation
