Title: The Innovative Contributions of Stefan Hagmann

Introduction

Stefan Hagmann is a notable inventor based in Meierskappel, Switzerland. He has made significant contributions to the field of valve technology, holding a total of 3 patents. His work focuses on creating advanced solutions for fluid control, which are essential in various industrial applications.

Latest Patents

One of Hagmann's latest inventions is the pressure independent control valve. This innovative valve design features a valve body with an inlet, an outlet, and a flow channel that connects the two. A hollow piston is strategically placed within the valve body, allowing it to move and maintain different fluid pressures in the flow channel and inside the hollow piston. The design includes a chamber and a biasing member that urges the hollow piston towards the chamber, ensuring consistent pressure throughout the system.

Another significant invention by Hagmann is the flow regulating valve. This valve combines two throttle locations within a single housing. One throttle location is adjusted to maintain a constant differential pressure across the other throttle location. This design allows for flow control that is dependent solely on the degree of opening, rather than the differential pressure. The cone of the second throttle location consists of at least two individual portions that can be displaced relative to each other, providing a variable effective cross-section for the throttle location. This innovative approach is particularly suitable for controlling liquid flows in heating solutions.
