Abstract

Improved valve assemblies (e.g., multi-position valve assemblies) are provided. More particularly, the present disclosure provides for high efficiency multi-position rotary backwash valve assemblies. In exemplary embodiments, the present disclosure provides for a four-position rotary high efficiency valve assembly for a swimming pool or spa filter. The present disclosure provides multi-position valve assemblies having infrequent maintenance and allowing for user-friendly service. The present disclosure provides for improved multi-position valve assemblies and related features, systems and methods of use. Improved, convenient and effective systems and methods for utilizing improved multi-position valve assemblies (e.g., high efficiency multi-position rotary backwash valve assemblies) are provided. The valve assembly can be utilized in fluid systems as a flow control assembly (e.g., as a backwash valve associated with a pool or spa filter).

Dependent claims

A valve assembly comprising:

a housing extending from a first end to a second end and defining a receiving cavity between the first and second ends, the housing having a first source port, a second source port, a first filter port and a second filter port;
a first pocket and a second pocket positioned on an interior surface of the housing, the first pocket extending around and in communication with the first and second source ports, and the second pocket extending around and in communication with the first and second filter ports;
a first seal carrier releasably disposed in the first pocket, the first seal carrier including a first aperture in communication with the first source port and a second aperture in communication with the second source port;
a second seal carrier releasably disposed in the second pocket, the second seal carrier including a first aperture in communication with the first filter port and a second aperture in communication with the second filter port;
a hub member movably disposed in the receiving cavity between the first and second seal carriers, the hub member including a first aperture, a second aperture, a third aperture and a fourth aperture, the hub member defining a first channel from the first aperture to the third aperture, and the hub member defining a second channel from the second aperture to the fourth aperture;
wherein when the hub member is moved to a filter position, the first aperture of the hub member is aligned with the first source port, the second aperture of the hub member is aligned with the second source port, the third aperture of the hub member is aligned with the first filter port, and the fourth aperture of the hub member is aligned with the second filter port;
and
wherein when the hub member is moved to the filter position, fluid can flow from the first source port through the first channel of the hub member and through the first filter port, and through the second filter port through the second channel of the hub member and through the second source port.
