A diverter valve for conveying material to be conveyed, the diverter valve being cleanable using a method for CIP cleaning, comprises a housing with at least three passage openings to feed or discharge the material to be conveyed, the passage openings defining a conveying plane. The diverter valve further comprises a rotary part having an axis of rotation and an outer contour designed conically in relation to the axis of rotation at least in sections, the rotary part being arrangeable in the housing in a sealed manner, the rotary part being displaceable along the axis of rotation in an axially driven manner and being arranged such as to be drivable for rotation about the axis of rotation, the axis of rotation being oriented perpendicular to the conveying plane, a passage duct arranged in the rotary part, which—depending on a rotary position of the rotary part—connects in each case two passage openings for conveying material along the passage duct through the diverter valve. The CIP cleaning method of a diverter valve of this type comprises the pulling back and rotating the rotary part into an intermediate position to clean and then dry the diverter valve intensively. A particular feature is the embodiment configured without drainage in the housing of the diverter valve.

A valve system has an apparatus formed with a plurality of material inlet ports, a flushing inlet port, and an outlet port and respective supplies of at last two different liquid materials. The supplies are each connected to a respective one of the material inlet ports, and a supply of flushing medium is connected to the flushing inlet port. A rotor at the apparatus is formed with a passage and shiftable between a plurality of positions in each of which a respective one of the inlet ports is connected to the outlet port. A controller moves the rotor between the positions such that, after each time the rotor is in a position connecting one of the material inlet ports to the outlet port and material has passed through the passage, the rotor is moved into a position connecting the passage with the flushing inlet port for flushing out the passage.

An inflatable device equipped with a guiding mechanism and methods of installing the inflatable device to form a temporary barrier within a gas turbine engine are provided. In one aspect, an inflatable device includes a backbone and an inflatable bladder connected thereto. The backbone is formed of a flexible and inextensible material. The inflatable bladder is formed of an expandable material. To install the inflatable device within an annular chamber of a gas turbine engine, the backbone is inserted into a first access port of the engine and is moved circumferentially around the annulus of the chamber. The backbone is retrieved through a second access port. The inflatable bladder is moved into position within the chamber by pushing the backbone into the first access port and/or pulling the backbone out of the second access port. When positioned in place, the inflatable bladder is inflated to form an annular seal.

The firearm barrel cleaning system selectively cycles a stream of ultrasonic cleaning fluid through the barrel of a firearm, and further selectively ultrasonically induces cavitation within the cleaning fluid in the barrel for ultrasonic cleaning. The firearm barrel cleaning system includes a receiver assembly having a first end adapted for receiving the stream of cleaning fluid and a second end is adapted for insertion into the firearm receiver and sealing against a first end of the barrel to eject the stream of cleaning fluid into the barrel. A cap structure, having an outlet hose connector is clamped over the muzzle end of the barrel of the firearm. A pump selectively circulates the cleaning fluid through the receiver assembly, the barrel and out through the cap structure. An ultrasonic transducer is mounted on the receiver assembly for selectively inducing cavitation in the cleaning fluid.

A method (400) for restarting flow in a waxy crude oil transporting pipeline (100), comprising: dividing (402) the gel plug into plurality of smaller gel segments (112, 114, 116) by removing a fraction of gel volume creating plurality of voids (132, 134), introducing (404) a compressible fluid into each of the voids; and applying (406) a pressure at first end (112A) of a first gel segment (112) contiguous to a pumping unit thereby creating a high pressure gradient between first end and second end (112B) of the first gel segment, causing the first gel segment to degrade and move towards a first void (132) thereby compressing the compressible fluid, the movement of the gel segment deforms and breaks the gel segment whereby the broken gel segment migrates towards a next gel segment (114) until all the gel segments are sequentially broken and flow of the waxy crude oil restarts.

A sanitary valve including a body including at least two body openings; a plug disposed within the body, rotatable around a vertical axis, moveable along the vertical axis within the body, and including a plug top surface and at least two plug openings; a stem including a first stem end attached to the top plug surface and a second stem end; and an actuator attached to the second stem end and operable to rotate the stem and the plug around the vertical axis and to move the stem and the plug along the vertical axis.

A method for reducing emissions from a vessel includes isolating the vessel from a downstream fluid flow line, purging a fluid from the vessel by injecting purging media into the vessel to push the fluid through a check valve of a vent tubing and into the downstream fluid flow line, and draining the purging media from the vessel. A first end of the vent tubing is coupled to the housing of the vessel, and a second end of the vent tubing is coupled to the downstream fluid flow line. Further, the vent tubing includes a check valve disposed between the first end and the second end, and the check valve is configured to allow fluid to flow from the housing to the downstream fluid flow line.

A pipe cleaning assembly has a connection fixture having a body defining a cavity. A first aperture, opposing second aperture coaxially aligned with the first aperture, first auxiliary aperture, and opposing second auxiliary aperture coaxially aligned with the first auxiliary aperture are in fluid communication with the cavity. A first connection flange extends from and surrounding the first aperture and a second connection flange extends from and surrounding the second aperture. A rotatable bonnet inserted through the second auxiliary aperture and includes a cylindrical wall having an open first end, an end wall at a second end, and a plurality of openings through the wall. An actuator is mounted to the bonnet with an actuator shaft extending through an opening in the end wall. A valve plug is secured to the actuator shaft and positioned within the bonnet.
