Jacob two-way valves

Two-way valves and modular pipework

The quality of Jacob’s two-way valves results from specific know-how with respect to press-moulded half-shell production. The extended bulging shape, produced using precision tools developed by the company, makes it possible to construct an inlet collar that is large enough prevent any reduction in cross-section. This also protects it from wear, which is particularly advantageous where sensitive products are to be conveyed. The form is pressed flat from the sides, which allows the inner flap to close more effectively. Users of two-way valves with a particular outer diameter usually expect that the internal diameter will be correspondingly large. In practice, however, considerable reductions in cross-section, depending on the type of construction, are the

norm. Jacob states that its valves have no such surprises, and that the valves also provide accuracy of fit, leak-tightness, a wear resistant design and unproblematic disassembly and replacement of parts. The Jacob modular pipework system (DN 60-800mm standard diameters) is used in many areas of industry, for the construction of bulk material conveyance systems and dust extraction or ventilation pipelines. Examples can be found in the food and luxury goods industry (coffee, cocoa, sugar, grain, tobacco), in concentrated feed production plants, in the packaging industry, the chemical, pharmaceutical and plastics industries (granulated material), in environmental engineering, recycling, automotive engineering, the chip industry, mechanical engineering,

the paper industry and the construction materials industry.

Jacob can provide short delivery times and easy-to-install pipe systems with wall thicknesses of 1 to 3mm using pull- ring connections or loose flanges, for all industries whose production processes require pipework systems made of stainless steel or powder-coated metal. The company’s 3D service provides customers with a DVD containing drawings of the pipes and fittings, as a practical and time-saving aid for creating engineering drawings. The new Jacob product catalogue can be requested from the company’s website.
