Title: Innovations by Inventor David E. Walrath

Introduction

David E. Walrath, an accomplished inventor based in Laramie, Wyoming, has made significant contributions to the field of valve technology. Holding a total of four patents, Walrath's work focuses on enhancing flow control mechanisms to achieve higher efficiency and reduced pressure drops in various applications.

Latest Patents

Walrath's latest inventions include an innovative "Apparatus and method of flow control through a valve." This design introduces an axially-rotated valve utilizing an axial eccentric split venturi system. This unique configuration allows for increased flow rates while minimizing pressure drop. The valve features two portions, with at least one being rotatable in relation to the other. Notably, the cross-section of the eccentric split venturi can have a non-axisymmetric shape, such as a semicircular cross-section, facilitating both optimal throttling capabilities and maximum flow capacity.

The applications of his inventions extend to freeze-resistant axially-rotated valves, which can transition from fully open to fully closed in just half a rotation. Furthermore, a well-designed internal wide radius elbow, connected to the rotatable portion of the venturi, aids in directing flow with reduced friction losses. The valve actuator operates in an axial manner, positioned outside the axial flow path to further enhance performance by minimizing friction.
