Abstract: There is provided a fluidic pinch valve system 10 for interrupting the flow of material through a conduit assembly. The fluidic pinch valve system 10 generally includes a substantially rigid valve body 100; an axially extended tube member 200 disposed within the valve body 100; and, an injection mechanism 300 coupled to the valve body 100 for injecting a fluid therein. The valve body 100 includes first and second ends and a wall portion 110 extending therebetween. Within the wall portion 110 is formed a bore extending axially from the first end to the second end. An injection port 140 is formed through the wall portion 110 to be in open communication with the bore. The tube member 200 is disposed within the valve body's bore and is formed having distal first and second sealing portions 120a, 120b and a sidewall portion 210 extending therebetween to define an axial passage.

Abstract: A tower press filtering system (1) is provided. System (1) includes a frame assembly (10) having at least one support engagement portion (14); a collapsible filter tower assembly (20) having a plurality of displaceable filter plate members (20); a press assembly (30) having a support plate member (300), a compression mechanism (320), and a press plate (326); and, a stabilization assembly (40) for automatically maintaining press plate (326) in a fixed planar orientation during displacement thereof. System (1) also includes a port assembly (50) having a substantially rigid conduit segment (52) that maintains coupling with the manifold section (210) of at least one filter plate member (200). System (1) also includes a mechanism by which the coupling of each compression mechanism (320) employed may be adjustably coupled to support plate (300).

Abstract: An interchangeable pinch valve system (10) is provided with a valve body (20) having a longitudinal dimension which is substantially identical to standard longitudinal dimensions for ball, gate and the like type valves of similar flow path diameter. The reduced longitudinal dimension of pinch valve system (10), as compared to prior art systems, is achieved by a flexible-walled tubular sleeve (50) having a pair of transversely directed folds (60, 62) which provide sufficient sleeve material to enable the pinch closing of the flow passage (52) without substantially stretching the tubular sleeve wall (51). The valve body 20 is provided with a pair of recessed openings (22, 24) formed in the interior of valve body wall (21) in parallel spaced relation transverse to the fluid flow axis of the valve for receipt of the respective folds (62, 60), whereby the tubular sleeve (50) is in contiguous contact with the interior surface of valve body wall (21).
