A flow rate control device includes a needle valve mounted within a body section and is configured such that the needle valve is advanced and retracted within the body section by the rotation of a handle, thereby adjusting the flow rate of fluid flowing between a first port and a second port. The handle is surrounded by a cover to prevent a change in the adjusted flow rate.

In one embodiment, a manifold apparatus may include a number of housings. The housings may receive an electrical or a fluid conduit. The manifold apparatus may also include an actuation mechanism of each of the number of housings configured to control a supply of electricity or fluid from the respective electrical or fluid conduit to one or more industrial automation equipment, and a locking mechanism including a number of armatures. Each of the number of armatures is associated with a respective housing of the plurality of housings, and each of the number of armatures is configured to physically prevent a respective actuation mechanism of the respective housing from changing states.

A control valve assembly includes a valve body having inlet and outlet ends, and an endless valve seat therebetween. A clapper disk is pivotably mounted within the valve body, and is pivotable between a sealingly closed position and an open position according to a pressure differential across the clapper disk. A U-shaped arm is rotatably supported in the valve body, and rotatable between a first position, wherein a bight of the U-shaped arm is positioned out of an operational range of movement of the clapper disk such that the clapper disk is freely movable between the open and closed positions thereof, and a second position, wherein the bight of the U-shaped arm engages and maintains the clapper disk in the sealingly closed position thereof. A selectively rotatable control arm operatively coupled with the U-shaped arm and utilized to move the U-shaped arm between the first and second positions thereof.

A method for filling and venting a device for extracorporeal blood treatment is disclosed, such as a patient module in a heart-lung machine, without attached patient. A filling liquid from a filling liquid container located higher than the device flows by gravity via a venous side of the system into a reservoir and flows onwards into a blood pump located at the lower end of the reservoir, wherein a first controllable valve (HC1) for a venting line of a filter is opened and, after the response of an upper filling level sensor in the reservoir, is closed. An upper level of the filter is positioned higher than the upper filling level sensor, and a start-stop motion of the blood pump is performed, as a result of which a stepped flooding of the filter is made providing for an advantageous de-airing of the device.

The subject matter of this specification can be embodied in, among other things, an apparatus that includes a valve with a valve housing having an axial bore, a first inlet port, a first outlet port, and a piston located within the axial bore and having a first fluid passage and configured to allow reciprocal axial movement of the piston within the axial bore between a first position in which the first fluid passage aligns axially with the first inlet port and the first outlet port to form a first fluidic circuit, and a second position in which the piston blocks at least one of the first inlet port and the first outlet port. The apparatus also includes a lockout assembly configurable to fix the piston into a selected position in a first configuration, and not interfere with reciprocal axial movement of the piston in a second configuration.

A valve lockout device includes an elongated main body defining an interior cavity for receiving a valve to be secured. A cap with a notch for receiving a cable is affixed to one end of the main body, with a wing pivotably attached to the cap so that the wing movable between an open position and a closed position. The wing in the closed position is operable to secure a cable with the notch in the cap. With the lockout device in place over a valve and a cable secured around the valve and to the lockout device, the valve is secured against operation and users and operators are notified of the lockout condition.

A movable shutter for a fluid conduit including two half-bodies consisting of a tube that forms a conduit, to the ends of which are affixed a flange and a plate having a bearing surface; a gate with a body defined by two longitudinal surfaces located opposite the bearing surfaces, which gate is mounted movably between the bearing surfaces, between a closed position and an open position; and a locking mechanism suitable for keeping the plates in a position in which they are either separated or close together, wherein at least one protruding element is provided on at least one of the bearing surfaces or on at least one of the longitudinal surfaces, such that if the gate is not properly positioned, the protruding element forms an obstacle that prevents the locking mechanism from keeping the plates in the position in which they are close together.

The invention relates to a torque support for a valve lock (5) in order to prevent a rotation of the lock with respect to the valve (1), wherein a connection housing (8) adjoins the valve lock and at least one boom (9, 9a) carried by the connection housing rests against the valve housing in the pivoted-out end position. Similarly, the torque support can also be connected to the valve housing and the boom can rest against the connection housing, or the connection housing is integrated in the valve lock.
