摘要： A filter bag assembly includes: a flexible first sheet; a flexible second sheet overlying and secured to the first sheet so that a compartment is formed therebetween; a porous filter sheet disposed between the first sheet and the second sheet so as to divide the compartment into a first compartment and a second compartment; a first port secured to the second sheet so as to communicate directly with the first compartment; and a second port secured to the second sheet so as to communicate directly with the second compartment, the second port being spaced apart from the first port. The porous filter sheet is disposed so that fluid entering the first compartment through the first port must pass through the filter sheet before entering the second compartment or exiting through the second port.

摘要： A check valve assembly includes a first port fitting and a second port fitting with a base secured therebetween. The base has an annular sleeve encircling a seat, the seat having a central mounting hole and one or more flow channels passing therethrough. An umbrella valve includes a flexible sealing disk having an outer surface and an opposing inner surface, a mounting stem extending from the inner surface and projecting into the mounting hole of the base, the sealing disk being movable between a first position wherein at least a portion of the sealing disk sits on the seat so as to cover the one or more flow channels and a second position wherein the sealing disk is resiliently flexed so as to at least partially uncover the one or more flow channels. A retention plate is disposed between first port fitting and the seat of the base so that the retention plate sits against the outer surface of the sealing disk.

摘要： A filter bag assembly includes a flexible bag bounding a compartment that is configured to hold a fluid. An inlet port and an outlet port are each secured to the flexible bag so as to communicate with the compartment. A porous filter sheet is disposed within the compartment of the flexible bag so that fluid entering the compartment through the inlet port must pass through the filter sheet before exiting the compartment through the outlet port. A first retention seal secures the porous filter sheet to a portion of the flexible bag within the compartment, the first retention seal having an outer perimeter edge that forms an annular continuous loop.
