A grid valve may include an annular stationary plate having a first annular surface, and an annular rotatable plate disposed on the annular stationary plate and rotatable relative to the annular stationary plate. The annular rotatable plate may have a second annular surface, and each of the annular stationary plate and the annular rotatable plate may define a plurality of holes in the respective annular surfaces thereof. The grid valve may further include a first magnet disposed on the first annular surface and a second magnet disposed on the second annular surface such that the first magnet repels the second magnet.

Embodiments of the invention described herein thus provide improved flush valves that are designed with improved venting features and improved inlet designs. The described venting features and inlet designs, either alone or in combination, can help prevent ingestion of waste into the interior of the valve.

A valve sealing device for a tilting-armature valve, including: a sealing body having a first surface configured to close in a fluid-tight fashion a valve seat and/or an opening in a valve; and a retaining body which is arranged on a surface of the sealing body which is opposite the first surface, and is configured to secure the valve sealing device in and/or on a cutout in a valve, in particular in a cutout in a tilting armature of a tilting-armature valve, in particular in which the sealing body and/or the retaining body is essentially cylindrical in shape. A related method to make the valve sealing device and a tilting-armature valve that includes the valve sealing device are also described.

A bulk adhesive transfer system for transferring adhesive particulate to a melter includes a bulk supply and a transfer device, which may define a hopper of the melter, a mobile bin, and/or a buffer unit. The transfer device is configured to receive unmelted adhesive particulate from the bulk supply and then be selectively docked with the melter to transfer the adhesive particulate to the melter. The bulk adhesive transfer system may also include a knife gate valve device, which includes a plurality of ports that sequentially open and close to control flow of the adhesive particulate towards the melter. The bulk adhesive transfer system simplifies refilling operations for a melter while enabling continuous operation of the melter, even when the transfer device is undocked for removal from the melter.

A valve in which the flow control element includes a fixed disk and a rotatable disk, and a Venturi nozzle for measuring flow through the valve, arranged in a straight configuration.

A valve assembly that may include a stationary device that may be configured to couple to a fluid conduit within the fluid conduit and may include plural opening elements defining a plurality of apertures for passage of a fluid to flow therethrough. The valve assembly may also include a movable device having plural closing elements corresponding to the apertures, and each closing element may be configured to slide into contact with a corresponding aperture to reduce or prevent a flow of the fluid through the corresponding aperture, and the closing element configured to spread a force of the fluid across a face of the closing elements.

A flow rate control valve has a waterproof function of a driving motor. The flow rate control valve is for transferring a fluid pumped by a water supply pump to a nozzle unit and a nozzle cleaning unit for cleaning the nozzle unit. The flow rate control valve includes al least one housing in which the fluid pumped by the water supply pump is accommodated, and at least one driving motor configured to change a communication area of each of the at least one housing, the nozzle unit, and the nozzle cleaning unit by rotation. At least one sealing adapter is formed between the at least one housing and the at least one driving motor so as to prevent the fluid from flowing into the at least one driving motor.

A reactive particles supply system that may include an adjustable gas supply unit that is arranged to supply gas and to set a gas condition, a reactive particles supply unit that may be arranged to receive the gas, and an adjustable reactive particles output unit that may include a reactive particles input, a second reactive particles output, and a reactive particles path. The second reactive particles output is configured to output reactive particles towards an opening of a vacuumed chamber. The adjustable reactive particles output unit is arranged to mechanically configure at least one element of the reactive particles path according to the reactive particles condition.

A valve in which the flow control element includes a fixed disk and a rotatable disk, and a motor operable to rotate the rotatable disk. The motor is disposed in the bore of the valve, aligned with the long axis of the valve body and the axis of rotation of the rotatable disk.

A rotary valve system includes a first body having a first plurality of fluid channels. The first fluid channels have a common first inlet to receive a fluid and a first outlet. The system includes a second body coupled to the first body. The second body has a second plurality of fluid channels. The second fluid channels have a second inlet and a second outlet. The system includes a plate assembly having a plate coupled between the first body and the second body. The plate is movable between at least a first, open position in which the first outlet of at least one of the first fluid channels is in fluid communication with the second inlet of at least one of the second fluid channels and a second, closed position in which the second inlet of each of the second fluid channels is substantially completely obstructed by the plate.
