DAB Dobermann Slide Valves

The D Range – medium heavy duty slide valves.

These robustly constructed valves are intended for general purpose use on medium/heavy duty applications and typically have openings of 300-1500 and beyond. Their design and construction can change significantly depending upon their application, but as fabricated units they can be readily customised to suit most requirements. Typical duties are bin, hopper and large silo isolation, screw feeder and conveyor shut-off, in-flight catchments, and weighing applications where a variable trickle feed option may be required.

• Construction – mild steel, stainless steel contact parts, all stainless or composite specials.
  
  
• Inlets – square, round or rectangular.
  
  
• Outlets - square or rectangular with optional transition piece to round flange or stub.
  
  
• Operation – manual (push/pull, handwheel or chainwheel), electro-pneumatic, motorised or hydraulic.
  
  
• Deflectors – Vertical by preference as this leaves no obstruction, hang-up or wear area exposed to the product flow. Where a common inlet and outlet size are essential, inclined deflectors may be used.
  
  
• Slide plate – thickness to suit duty. A knife edged may be appropriate for some duties.
  
  
• Plate seal – glanded type with appropriate packing or double retained felt type.
  
  
• Plate support – PETP, Nylon, mild steel or stainless steel eccentric studs.
  
  
• Finish – Blue/silver hammer, natural, bead blast, polished or custom.
