With the function and benefits of the Varilte Evolution, the Evolution PSV (Pressure Setting Valve) has the added benefit of taking the guesswork out of cushion adjustment and makes it automatic! The PSV works by sensing the amount of internal cushion pressure. As air is released, internal pressure decreases as the user is immersed in the cushion for effective pressure distribution. Sitting on a fully inflated Evolution PSV cushion, the client simply opens the PSV to the appropriate position. When the PSV senses that enough air has been released, it automatically shuts off the flow. The client then closes the PSV. Adjustment is simple and consistent.
