Abstract: A self-cleaning filter assembly includes a cylindrical cartridge filter element supported on a coaxially mounted hydrodynamic bearing for rotation of the cartridge filter element about its longitudinal axis. The cylindrical cartridge filter element includes a hollow interior for receiving filtered water. A water spray manifold is provided proximate to the cartridge filter element and includes spray nozzles for providing a water spray capable of rotating the cartridge filter element about its longitudinal axis. A diverter valve receives flow of water to be filtered. With the diverter valve in a first position, the received flow of water submerges the cartridge filter element, with the filtered water received at the hollow interior of the cartridge filter element. With the diverter valve, in a second position, the received flow of water is provided to the water spray manifold causing it to fill under pressure.

Abstract: A cylindrical heat exchanger member can be formed from multiple stacked ring shaped tubular members wherein an inlet and outlet of each ring shaped member terminate at a single header interface, thus permitting access to the inlet and outlet of each ring shaped member at a single location which enables rapid configuration of an combination of flow paths through the multiple ring shape members as well as simple and efficient cleaning of each ring shaped member.

Abstract: 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.

Abstract: A valve is disclosed. The valve includes at least two valve bodies that each have an annular chamber for operably supporting a flow control member. An adjoining member is attached between the valve bodies and houses an adaptor for engaging a portion of each flow control member such that rotation of one flow control member rotates the other flow control member. Each flow control member can engage the adaptor at a plurality of orientations about an actuation axis that extends through the valve. A method for reorienting to interconnected valve bodies relative to each other is disclosed.
