Shick Esteve’s Tube Selector Valves are constructed for use in both vacuum and pressure pneumatic conveying applications. The TSV uses an exclusive diverting position design for effective convergence or divergence of material. The piston is raised or lowered into position, without rotation, by selectively injecting compressed air into each end of the cylinder. This movement allows the horizontal borings, located on two separate planes within the piston, to align with the housing ports to achieve a straight-through or divert position. Shick Esteve’s TSVs can handle a maximum line pressure of 50 PSI with an air supply of 80 to 100 PSI of clean, dry air without lubrication.
