A system for managing flexible conduit or tubing used in pharmaceutical, bioprocess, or food/dairy applications includes a segment of flexible conduit or tubing and a plurality of conduit tracks, each conduit track including a conduit channel disposed on a first side thereof and extending along the length of each respective conduit track and dimensioned to receive the segment of flexible conduit or tubing therein, each conduit track further including a connector channel disposed on a second, opposing side and extending along the length of each respective conduit track and containing the one or more connectors that connect adjacent conduit tracks. The conduit tracks can be connected to each other or other process components.

The invention relates to a valve body for a process valve, wherein an interior space of the valve body connects at least two ports to one another in a fluid-conducting manner, wherein at least one partition wall separates adjacent flow chambers of the interior space from one another, and wherein an outer shell and the at least one partition wall, at least in a blocking portion of the valve body extending essentially perpendicularly to a blocking axis, are made of a flexible material.

A pinch valve 1 comprises a tube body 3 made of an elastic material having a flow path formed inside, a pressing part 4, a rod member 6 attached to a front end of the pressing part 4, and a coupling part 35 provided on the outer surface of the tube body 3 and coupling the rod member 6 to the tube body 3 in a transverse arrangement with respect to the tube body 3, wherein pressing or releasing the tube body 3 by the pressing part 4 through the rod member 6 makes the tube body 3 deform and opens or closes the flow path.

A dense phase pump has two housings that are attached together using a single releasable fastener. The fastener can be released to allow the two housings to be separated thereby providing access to replaceable components. The replaceable components may include one or more pinch valves or one or more barrier elements. A pinch valve for a dense phase pump has a shape or profile for aligning the pinch valve when the pinch valve is installed in a pinch valve body. The pinch valve optionally has two end flanges, with each end flange having a shaped periphery. The two end flanges may have the same size and shape so that the pinch valve can be installed in either of two orientations that are inverse. A dense phase pump has a pump chamber that can be purged by purge gas that enters the pump off-axis from a purge path axis.

A fluidic device comprises a channel, a gate, and one or more additional elements. The channel is configured to transport a fluid from a source to a drain. The gate includes a chamber with an adjustable volume that affects fluid flow within the channel by displacing a wall of the channel toward an opposite wall of the channel based in part on fluid pressure within the chamber exceeding a threshold pressure. A high pressure state of the gate corresponds to a first chamber size and a first flow rate of the fluid. A low pressure state of the gate corresponds to a second chamber size that is smaller than the first chamber size and a second flow rate that is greater than the first flow rate. The additional elements are configured to reduce the threshold pressure past which the chamber decreases the cross-sectional area of the channel.

A valve device for controlling a fluid flow, in particular an air flow, having at least one inlet and at least two outlets, at least one of the outlets being fluidically connectable in each case to the inlet via a through-channel of at least one manipulable guide means. The through-channel of the guide means can be changed at least indirectly via a control fluid flow either with regard to at least a section of its internal cross section or can be rotated at least to a limited extent with regard to its orientation with respect to the outlets and the inlet can be rotated at least to a limited extent.

In one aspect, system to form a pneumatically-actuated transistor logic includes a first deformable conduit; a first extensible bladder disposed at a first location along the first conduit; a first structure in proximity with the first bladder and configured to constrain expansion of the first bladder; wherein the first structure and the first bladder are configured to allow flow of fluid through the first conduit when the first bladder is in a first state and to prevent flow of fluid through the first conduit when the first bladder is in a second state.
