Pinch and knife gate valves from Larox Flowsys are said to be ideal for use by process industries worldwide carrying out abrasive, corrosive and other demanding shut-off and control applications.

According to the company, its manual and automatic pinch valves are suitable for shut-off or control applications that involve abrasive or corrosive slurries, powders or coarse substances.

The operating principle of a Larox valve is said to be 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 centreline.

The pinch valves provide a 100 per cent tight shut-off.

The highly resistant and durable sleeve forms an integral part of the valve structure and is the only part in contact with the medium.

Centreline closing minimises sleeve stretch.

The encapsulated stem mechanism is protected and lubricated to ensure trouble-free operation.

Stainless steel stem and sidebars improve wear and corrosion resistance, according to the company.

The enclosed Larox valves feature external open/closed position indicators.

Optional features include an alarm sensor for remote leakage detection.

Maintenance is said to be trouble free as sleeve changes can be done without special tools.

Larox heavy-duty knife gate valves are built with a cast body and they feature a heavy-duty stainless steel blade.

Removable seats on either side of the gate provide a bidirectional bubble-tight seal, with no metal parts in contact with the slurry.

In the open position, the two sleeves seal against each other in the centre of the valve, providing a full bore through which the slurry can travel without being in contact with any metallic components.

Closing the valve forces the gate progressively down between the two mating sleeve ends until it reaches the fully closed position, at which point the sleeves seal tight against either side of the gate, effectively sealing and completely containing the line pressure.
