A diaphragm valve, comprising: a valve body in the form of a cylinder defining a center line and having a passageway defined by a length axis, said valve body having a cross section which is substanti

The invention is particularly applicable to a diaphragm valve for use in biotechnological applications and will be described with particular reference thereto. However, it will be appreciated that the

A diaphragm valve is provided with an improved sealing surface and a mechanical flow regulator for precise flow control. The valve has a body with an inlet chamber and an outlet chamber. Passages exte

It is therefore, an object of the present invention to provide the existing state-of-the-art with an improved flexible diaphragm valve of the type discussed above.
