'Iris' Valve ControlsGravity Discharge OfFree-Flowing Bulk Materials

Salina Vortex' Iris Valve, which is designed to control the gravity discharge of free-flowing bulk materials from bins, bulk bags, chutes and hoppers, comes in two models: the IP (infinite position) and the QL(quick lock).

The IP Model is said to offer infinitely adjustable positioning between fully open and fully closedby rotating the handle through a 180-deg arc. It is available in lightweight aluminum construction with a bronze control ring or all stainless steel construction in 4-, 6-, 8-, 10- and 12-in sizes.

The QL Model offers rapid, multiple-set positioning through a trigger-type handle lock. Itis available in 4-, 8- and12-in. sizes in aluminum construction with self-lubricated, hard plastic control ring and handle. A 15-in. size is available in aluminum with Teflon-coated aluminum control ring and handle.

A form-fitted nylon fabric sleeve is said to provide a dust-tight seal without damaging the product being handled. An anchored wire sleeve frame eliminates sleeve slippage, which is associated with traditional iris valves.

Optional sleeve material for both models, as well as 'double sleeving' for the QL model, is available for difficult, more abrasive or custom applications. For pricing information, contact the company by using the Key Contact Directory on p 42.
