A method of cleaning a complex powder transfer system including providing a powder transfer system having a washing fluid source, a spray device valve in fluid communication with the washing fluid source, a backflush valve in fluid communication with the washing fluid source, a receiving device having an upper chamber, a lower chamber, and a membrane filter disposed between the upper and lower chambers. The method includes opening the backflush valve to initiate a backflush cycle, running the backflush cycle to wash the upper chamber with a fluid, and closing the backflush valve after the backflush cycle completes. The method includes opening the spray device valve to initiate a spray device cycle, running the spray device cycle to wash the lower chamber with fluid, and closing the spray device valve after the spray device cycle completes. The method includes opening a pressure valve to provide PCA to the receiving container.

A flue pipe clearance device is provided. The flue pipe clearance includes a cap portion dimensioned and adapted to operatively associate with an end of an outbound pipe. The flue pipe clearance device includes an inlet that fluidly communicates to the end of the outbound pipe when the cap portion and outbound pipe are operatively associated. Pressurized gas may be selectively applied to the inlet so as to urge the evacuation of debris or fluids in the outbound pipe through an exhaust end of the outbound pipe.

A method and apparatus for cleaning and treating HVAC systems with a deployed agent preferably includes an aerosol generating device, a plurality of vent sealing devices, an outlet connection conduit and an inlet connection conduit. The HVAC system includes at least one supply duct and at least one return duct. The aerosol generating device includes an inlet and an outlet. The outlet is connected to a return vent of the at least one return duct with the outlet connection conduit. A supply vent of the at least one supply duct may be connected to the inlet with the inlet connection conduit. However, the inlet does not have to be connected to the supply vent if the aerosol generating device is retained in an enclosure. A booster chamber may be used to increase the flow rate of the deployed agent from the aerosol generating device.

An apparatus has a plurality of inlet ports each connectable to a material supply container and an outlet port. A disk-shaped valve body has a first side and an opposite second side with a straight throughgoing passage from the first side to the second side, the body being displaceable relative to the inlet ports to provide a switchable connection between a respective one of the plurality of inlet ports and the outlet port. The passage can be also be connected with a respective one of the various inlet ports to enable feeding of different materials successively to the outlet port. One of the inlet ports is a flushing medium inlet port of a flushing device, and the passage can connected with the flushing medium inlet port by displacement of the valve body for flushing the passage.

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, whichdepending on a rotary position of the rotary partconnects 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.

There is disclosed a method and apparatus for finishing an internal channel of a component. The method comprises installing the component in a flow circuit which is configured to drive a fluid flow through the internal channel and controlling the fluid flow through the internal channel so that cavitation bubbles are continuously generated by a hydrodynamic effect to erode the internal channel by implosion of the cavitation bubbles. The fluid flow may comprise abrasive media which may abrade the internal channel.

A method is provided involving a gas turbine engine system. The method includes configuring a plug within a fluid passage in the gas turbine engine system, where the plug is between first and second portions of the fluid passage. Material is removed from an interior surface of the fluid passage in the first portion of the fluid passage to provide removed material, where the plug substantially prevents the removed material from entering the second portion of the fluid passage. The removed material is directed out of the fluid passage. The plug is removed from the fluid passage.

A water-aided plunger assembly for removing plumbing blockages and fixing clogged drains. Once fully assembled the water-aided plunger includes a plunger arm with a hollow channel to facilitate passage of pressurized water therethrough, a plunger head to create a suction force, a tubular house to connect the assembly to a water source, and a faucet adaptor to ensure connection across a wide range of faucets of varied shape and size. The faucet adapter also creates a vacuum seal around the faucet acting as the water source so as to preserve the vacuum and suction force required by the plunger head.

An improved pilot system that allows an automatic maintenance valve to be flushed of buildup. The improved pilot system is used to flush the three chambers of an automatic control valve. The pilot system comprises of lines, ball valves, a strainer, a restrainer plug, a flow stabilizer, a flow restrictor, a pressure reducing pilot, and a couple of isolating valves.

A method of cleaning a cylinder head using pressurized fluid and a tooling assembly for the same includes a jet ignition insert attached to a spark plug well defined by the cylinder head. The insert defines an opening in fluid communication with the spark plug well. The insert includes an end wall attached to the insert distal end to close one end of the opening and the end wall defines holes. The tooling assembly includes a tool configured to clean the insert. A first engagement surface of the insert and a second engagement surface of the tool engage each other to form a seal that surrounds the holes of the insert such that the pressurized fluid is directed through the holes and into the opening of the insert during the first operation procedure of the tooling assembly to flush debris out of the holes of the insert.
