Reliable Heavy Duty Pinch Valves for Shut-Off and Control Applications

Flowrox heavy duty pinch valves are designed for shut off and control applications involving abrasive or corrosive slurries, powders or granular substances. In the open position, the valve is full bore with no flow restrictions. During closing, two pinch bars squeeze the valve sleeve shut on the centerline. Bubble tight shut-off is provided even if solids have built up on the sleeve wall. Flowrox heavy duty pinch valves are benchmark in heavy industry and most demanding conditions.

  • Typical payback time 15 months in on/off applications
  • Save 2/3 on spare part costs
  • Reduce downtime costs by 70%

Heavy Duty Pinch Valve

Flowrox heavy duty pinch valve is made to last and is ideal where shut-off and control applications involve abrasive or corrosive slurries, powders or coarse substances. The rubber sleeve is the only wearing part which significantly reduces maintenance costs and extends service intervals. Advanced flow control solutions paired with superior valve and elastomer technology meet even the most demanding customer specifications.

Flowrox pinch valves are ideal solutions where shut-off and control applications involve abrasive or corrosive slurries, powders or coarse substances. Our advanced flow control solutions meet even the most demanding customer specifications.

  • We provide tailor-made flow control solutions precisely in accordance with the customer specification
  • We offer comprehensive sizing and selection service
  • Low cost maintenance and long service intervals – the inside sleeve is the only replaceable part

Special for harshest control applications:

Flowrox extra thick polyurethane sleeve

For high-wear control valve applications, we can also provide Flowrox extra thick polyurethane (PU) sleeve. It is engineered for extreme sliding abrasion, low angular and low velocity impact conditions. For more information, click here.

  • Reduced total cost of ownership

Extra thick sleeve - Flowrox

Only part in contact with the abrasive slurry is the abrasion-resistant polyurethane inner lining of the sleeve.

Benefits & features

Improved process efficiency

100% tight shut-off even if solids have built upon the sleeve wall. When compressed, any crystallized particles flake off the sleeve surface.

Improved customers' productivity

Full bore: Ensured free flow of the medium and less pumping energy is required.

Ease of maintenance

Only the sleeve is in contact with the medium and is the only replaceable part. Can be easily changed on site.

Accurate control

Improved controllability with conical sleeve results in linear control curve.

Extended service intervals

High corrosion resistance and flexible sleeve.

Tailor-made for your processes

The construction and materials of the three main components (sleeve, body and actuator) can be tailored to suit your process conditions.
