Title: The Innovative Contributions of Arnold Dalene

Introduction

Arnold Dalene is a notable inventor based in Ringwood, NJ (US). He has made significant contributions to the field of valve technology, particularly with his innovative designs that enhance functionality and efficiency.

Latest Patents

Dalene holds a patent for a "Rotary ball valve with retracting seat." This invention features a valve body with spaced inlet and outlet ports that control the flow through an interposed ball. The ball is rotatable about a fixed axis that intersects the flow axis at its geometric center. In the closed position, an annular valve-seat member makes circumferentially sealed contact with the ball. This member is designed for axial displacement, allowing it to engage or disengage from the ball. The actuation of the valve is coordinated with the ball's rotation, ensuring that the valve-seat engages only when the valve is closed. This innovative design allows for smooth valve-opening rotation while maintaining clearance with the ball.
