Flowrox Sleeves
The core of the Flowrox pinch valve is the elastic sleeve, which is the
only part in contact with the medium. The full bore sleeve integrates
the valve perfectly to the pipeline, eliminates turbulence and
minimizes pressure losses. Technologically advanced sleeves
guarantee high wear and corrosion resistance, a trouble free
operation and extended lifetime.

SLEEVE DESIGN

Technical features
●
●
●

Pinch valves are commonly applied in aggressive, abrasive and corrosive
media types or in high-pressure applications. To stand these conditions
Flowrox sleeves are handmade layer by layer in a quality process covered by
ISO 9001:2000.
Outer layer – protects the sleeve

Size Range
25 mm – 1000 mm
Operating temperature
-50°C – +160°C
Operating pressure
from vacuum to 100 bar

Reinforcement cords – gives the sleeve
its pressure retraining capabilities
Inner layer – resistant to wear and
chemicals

Exellent wear resistance
High corrosion resistance
No turbulence
No jamming or clogging
No flowr restrictions
Reduced process downtime

High grade sleeve materials range from wear resistant styrene butadiene to
numerous other elastomers and rubber combounds. They are highly resistasnt
to abbrasive/corrosive slurries, powders and granular substances.

SPECIAL DESIGNS
Several sleeve design options such as a conical sleeve for control valves and
a vacuum sleeve for negative pressure applications are available.
Suction sleeve
Specially designed for negative pressure applications
such as suction lines and for applications where
sleeve pulsation occurs
Conical sleeve
Conical sleeves ensure the most accurate control in
flow control applications.
Sensomate sleeve
SensoMate sleeve detects and signals critical wear.
Polyurethane (PU) lined sleeve
Sleeve with polyurethane lining ensure improved
protection against wear.
