A valve is provided having a housing defining first and second flow areas. First, second and third flow ports open into the first flow area, while fourth and fifth flow ports open into the second flow area. A flow passage is provided having one end opening into the first flow port and another end opening into the second flow area. First and second flow control gates are disposed in the first and second flow areas, respectively, and are rotatable between first and second positions. With the first and second gates in the first position, the first gate seals off the third flow port opening such that the first and second flow ports are in fluid communication via the first flow area, and the second gate seals off the flow passage opening such that the fourth and fifth flow ports are in fluid communication via the second flow area. With the first and second gates in the second position, the first gate seals off the first flow port opening such that the second and third flow ports are in fluid communication via the first flow area, and the second gate seals off the fourth flow port opening such that the first and fifth flow ports are in fluid communication via the flow passage and the second flow area.

Backwash valve

A valve is disclosed. The valve has a housing that defines a central area and has at least two flow ports therethrough. A cover is provided that has a flapper assembly pivotally attached thereto. The cover is removably attachable to the housing in a plurality of orientations to selectively orient the flapper assembly adjacent any one of the ports such that fluid is permitted to flow into the central area of the housing through the adjacent port. The flapper assembly prevents the fluid from flowing back out of the central area through the adjacent port. The cover may have a transparent portion to permit the flapper assembly to be viewed and inspected during operation. A double seal arrangement is also disclosed.
