The Adjustable Sophy® Mini valve is a high-precision device of unparalleled simplicity.

The principle of the Sophy® valve resides in the variation in pressure exerted on a ball by a semi-circular spring at various points along its circumference. The spring is attached to a magnetic rotor which position can be non-invasively changed using an adjustment magnet. A series of indentations allows a variety of positions to be selected, each position representing a different pressure setting.

The Sophy® Mini Monopressure valve (SM1) is a low-profile high precision ball-in-cone valve. It has the small size, the shape of the Sophysa Adjustable Valves and is made of the same material.
