TECHNICAL DESCRIPTION

The proGAV 2.0 is a valve made from titanium.
It consists of an adjustable differential pres-
sure unit and a gravitational unit.

5. rotor
6. tantalum ball
7. sapphire ball
The adjustable differential pressure unit con-
sists of a stable titanium housing in which
a tried and tested ball cone valve (1) is
integrated in the proximal section. A torsion
spring (4) determines the opening pressure
of this unit. The pretension of the spring, and
therefore the valve opening pressure, can be
adjusted through the skin using a revolving
rotor on a bearing (5).
