Abstract: A pressure vessel in accordance with the present invention comprises a cover, movable between an open position and a closed position, and a clamp for releasably clamping the cover in its closed position. The clamp includes a handle for manually operating the clamp. The handle is movable between a first position, in which the clamp releasably holds the cover in its closed position, and a second position, in which the cover is free to be moved to its open position. The pressure vessel further comprises locking means, including a latch pin for releasably locking the handle in its first position upon actuation of the latch pin, and actuating means, including a flexible diaphragm which is responsive to an increase in pressure within the pressure vessel, for actuating the latch pin when the pressure within the vessel has reached a predetermined level.

Abstract: A flow control assembly is provided with a cartridge which includes a body sized and shaped so as to be received in a housing of fluid handling apparatus, such as duplex strainers and diverter valves. The body has a first chamber and a second chamber adjacent to the first chamber. The first chamber includes a first fluid inlet and first and second fluid outlets, while the second chamber includes second and third fluid inlets and a third fluid outlet. A first valve is movably positioned in the first chamber. The first valve is movable between a first position, in which fluid passes from the first fluid inlet to the first fluid outlet, and a second position, in which fluid passes from the first fluid inlet to the second fluid outlet. A second valve is also movably positioned in the second chamber.

Abstract: A sealing ring for use in connection with a filter bag assembly of a filter is disclosed. The sealing ring includes an annular body having an outer annular wall projecting from the body. The outer wall is flexible such that it can engage an adjacent surface of the filter in a liquid-tight manner for forming a seal between the surface and the sealing ring.
