The Core of Our Valve

The core of the Larox pinch valve is the elastic sleeve, which is the only part in contact with the medium. The full bore sleeve integrates the valve to the pipeline. This full bore design eliminates turbulence and minimizes pressure losses. Technologically advanced Larox sleeves guarantee high wear and corrosion resistance, a trouble free operation, and extended lifetime. Our sleeves are 100% tight.

Larox sleeves are handmade layer by layer in a quality process covered by ISO 9001:2000. The standard sleeve design consists of three sets of layers: the inner layer, the reinforcement layer and the outer layer.

A Wide Range of Material and Design Options

Pinch valves are often applied in aggressive, abrasive and corrosive media types, or in high-pressure applications. To cover a wider range of applications, our R&D has developed several sleeve materials and constructions to meet these industry specific needs. The high-grade Larox sleeve materials range from wear resistant styrene butadiene to numerous other elastomers and rubber compounds. These materials are highly resistant to abrasive and corrosive slurries, powders and granular substances. By introducing a HNBR, hydrogenated nitrile sleeve material, Larox sleeves can now handle temperatures up to 160°C.
