Pinch Valves

GENERAL INFORMATION

Pinch Valve DQV

The Pinch Valves are pressure controlled Shut-Off Valves. Neutral gases or liquids can be used as control medium. Pinch Valves can also be used as a regulating or dosing Valve if the tax pressure is changed, e.g. via a proportional pressure control Valve. Due to an extensive choice of elastomer for the special sleeve and different materials for the Valve body and flanges, the Pinch Valve finds application in many areas. Pressure and friction losses are insignificant due to the free passageway. By means of pressurization the sleeve closes the flow densely. Sleeves are closing densely within
liquid, gaseous and also within viscous fluent or powdery fluids.

  • Valve body and flanges made of aluminium alloy or stainless steel
  • Free Valve opening without pack up points
  • Cavity free
  • Long durability of the sleeve
  • Sleeve with FDA conform mixtures for the food area
  • Applicable in EX-zones according to ATEX due to conductible sleeves
  • Application also in a vacuum area
  • Maintenance-free work
  • Flange or thread connections
  • Flanges with special linings (silicone, stainless steel and other)
