Flowrox™ pinch valve type PVE

Flowrox PVE pinch valve has a closed housing design and consist of three main components: the sleeve, the body and the actuator. The sleeve is the only part that is in contact with the process medium. The construction and materials of all three main components can be selected to suit most process conditions.

The valve is full bore and the media is only in contact with the rubber sleeve. Self-cleaning Flowrox valves provide 100 % tight shut-off even if solids have built up on the sleeve wall. When compressed, any crystallized particles flake off the sleeve surface and are washed downstream. PVE pinch valves are ideal for shut-off and control applications involve abrasive or corrosive slurries, powders or coarse substances.

Properties
  • Easy Maintenance
  • Housing in Cast iron EN-JL 1040, Carbon steel 1.0619 and Stainless steel AISI 316, (some sizes available in polyurethane)
  • PVE valve handles abrasive media and is fit for the most demanding applications
  • Various sleeve material choices according to end-use applications
