VALVE WITH DUAL ROTATION VALVE MEMBER
Abstract:
A valve with a dual rotational valve member is provided. The valve includes a first valve member and a second valve member. An actuation arrangement is operably positioned between the first valve member and the second valve member to rotate the first valve member in a first direction and the second valve member in a second direction opposite the first direction. This counter-rotation of the first and second valve members selectively aligns or misaligns a pair of flow ports of the first valve member with a pair of flow ports of the second valve member. When the pairs of flow ports are aligned, the flow path of the valve allows for straight through flow of a fluid through the valve thereby decreasing turbulence, back pressure, and noise.
