ROTARY

GENERAL INFORMATION

Rotary Valve DKZ 103/110 APS®

Basis of the Rotary Valves are the over many years proved Shut-Off Valves of the centric APS class. They can be used for charging and blocking. The APS construction indicates that the sealing element is pressed pneumatically to the perimeter of the disk in position “closed”! A steady pressure tightness is still guaranteed with slight wears by the constant contact pressure of the sealing element of the Flap Valve. Therefore it shows a special suitability for abrasive bulk material. The Shut-Off Valve can be employed depending on the used sealing material in a temperature range of – 40°C up to + 200°C. For the triggering of the pneumatic seal Warex offers different solutions in which the seal can, if necessary, deflated with vacuum support or be charged with nitrogen.

  • minimized wear, by operation nearly frictionless
  • considerably extended durability with abrasive (non-adhesive) products
  • considerably lower torque, therefore smaller drives
  • maintenance-free design
  • exchangeable seals
  • EX type for application in 0/20 zones according to type test BVS03/Atex-H024X
  • Seals with a lateral projection and an additional seal face guarantee a perfect sealing between
    flanges without additional flange seals
  • Shafts and armature head qualified for the construction of the different drive possibilities, cutting point
    according to DIN/ISO 5211

1. Valve opened
The special APS shut-off valve (Air-Pressure-Sealing) has a valve disc which is smaller than the corresponding sealing sleeve. The disc can close easily.

2. Valve closed
There is still a small gap remaining between the valve disc and sleeve – in this state, the fitting can be opened again with minimal torque.

3. Valve pressed
When the valve is closed, air is blown evenly on the seal, which ensures a secure and gentle shut-off with minimal friction. This is a major benefit with aggressive bulk materials, in particular.
