Larox manual valves are ideal for shut off applications that involve
abrasive or corrosive slurries, powders or coarse substances. Our advanced
flow control solutions meet even the most stringent customer specifications.

The operating principle of a Larox 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 Larox valves provide a
100% tight shut-off.

Larox valves offer substantial savings through improved performance, longer
service lifetime and lower maintenance costs.
Modular Design
Our modular valve design has 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
tailored to suit most process conditions. Self-cleaning Larox 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.

The Built-in Quality of The Larox Valve
Larox valve builds on several quality components. The highly resistant and
durable sleeve forms an integral part of the valve structure and is the only
part in contact with the medium. Centerline closing minimizes sleeve stretch.
The encapsulated stem mechanism is protected and lubricated to ensure
trouble-free operation. Stainless steel stem and sidebars add to improved wear
and corrosion resistance. The enclosed Larox valves have external open/closed
position indicators. Optional features include an alarm sensor for remote
leakage detection. Maintenance is trouble free as sleeve changes can be done
without special tools.
