Flowrox pinch valves are ideal solutions where shut-off and control applications involve abrasive or corrosive slurries, powders or coarse substances. The number of designvariations is virtually unlimited as the modular structure of a Flowroxvalve enables the selection of any actuator, valve body construction and sleeve material to fit specific process conditions.The operating principle of a Flowrox valve is simple. In the open position, the valve is at full bore with no flow restrictions thus making the valve an integral part of the pipeline. During closing, two pinch bars squeeze the sleeve shut on the centerline. The Flowrox valves provide a 100% tight shut-off.

Modular Design

Flowrox modular valve design has three main components: the sleeve, the body and the actuator (manual, pneumatic, hydraulic and electric). 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 tailored to suit most process conditions. 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.

  • Size range: standard range from 25 mm to 1.000 mm
  • Temperatures: -50°C to +160°C
  • Operating pressures: vacuum to 100 bar

Flowrox provides pinch valves with enclosed, open, sealed and general line valve bodies.  We provide tailor-maid flow control solutions precisely in accordance with the customer specification.
