A valve assembly includes a valve body having a flow bore extending along a valve body axis from a first end to a second end, wherein at least one of the first end or the second end includes an opening adapted to receive a fluid end, the opening having an opening diameter sized to enable at least one of a valve member, a valve stem, or a valve seat to be installed through the opening. The valve assembly also includes an actuator adapted to drive movement of a valve member between an open position and a closed position. The valve assembly further includes a bonnet coupled to the actuator, the bonnet being coupled to the valve body at a top location, the bonnet being coupled to the valve body while at least one of the valve member, the valve stem, or the valve seat is installed through the opening.

The present invention is an elastic (mechanically stretchable), sanitizing pouch configured to receive and hold an Electronic Device of a predetermined configuration. The elasticity of the fabric used maximizes surface contact with the Electronic Device and the closeness of the fabric of the invention with the outside surfaces of the Electronic Device. A liftable and removable cover flap on the front of the invention is used to hold and access the inside of the invention. The back of the invention includes at least one pocket. The invention further includes a pull tab to help lift an Electronic Device out of the invention. While inside the invention, the silver ions are released in the fabric and inhibit the colonization of bacteria, viruses and fungus on the Electronic Device.

A slide valve having a valve disc that is slidably movable between a fully-retracted fully-open position and a fully-extended fully-closed tight shutoff position by an actuating stem. The actuating stem is flexibly coupled to the valve disc. The valve disc is selectively modulated between the fully-extended fully-closed tight shutoff position and a partially-retracted non-tight shutoff position to prevent sticking of the valve disc in the fully-extended fully-closed tight shutoff position.

A gate valve includes a valve body and a valve cover. The valve body includes a first opening, a second opening, a third opening, a flow passage from the first opening to the second opening, and a gate channel from the flow passage to the third opening. The gate channel has a central longitudinal axis and a ridge defining a perimeter of the third opening. The valve cover can fit over the third opening and, under force on the valve cover, exert a clamping force on the ridge. The clamping force has a first force component perpendicular to the central longitudinal axis and a second force component parallel with the central longitudinal axis. The first force component of the clamping force is toward the gate channel. The ridge includes a first surface configured to mate with a first surface of the valve cover.

A metering device for bulk material has a metering container with an outlet opening provided with a rim. A slide is connected to a slide drive and closes the outlet opening. The slide is provided with a slide rim. The rim of the outlet opening and the slide rim, as a function of a displacement travel of the slide in a displacement direction, determine a travel-dependent outlet cross section of the outlet opening. The rim of the outlet opening; or the slide rim; or the rim of the outlet opening and the slide rim extend at a slant to the displacement direction of the slide.

A valve plate has a plate portion with an elastomeric seal on a front face and an elongated connecting portion spaced apart from a rear face by a slot for fastening the valve plate to a valve rod. The extension of the connecting portion in the width direction is defined by opposing first and second side edges of the connecting portion when viewed in a plan view of the rear face of the plate portion. A connecting structure is configured in the connecting portion in a central region of the longitudinal extension of the first side edge of the connecting portion for connecting the connecting portion to an end portion of the valve rod. The connecting portion is reinforced in a region of its extension in the width direction adjoining the second side edge, relative to a region of its extension in the width direction adjoining the first side edge.

Two problems with existing electronically controlled mixing valves for domestic use is their size and difficulty accessing and repairing them. Their size means that they often become hidden behind wall linings, and because of the way in which they are plumbed into the pipework of a house, they are difficult to access and remove for repair or replacement. Disclosed is a compact and replaceable mixing valve cartridge that can be mated to a fixed fitting that is permanently plumbed into the pipework of a house. The compact size allows the cartridge to be positioned behind the type of removable face plates that are often installed over existing manually operated mixing valves. Simplified valve actuators and a compact mixing and temperature sensing configuration have facilitated the compact size. The valve cartridge can simply be accessed, unbolted and removed, without the need for extensive plumbing re-work.

A method of manufacturing a device includes thermally spraying tungsten carbine in feedstock that does not include Cobalt but that includes Nickel, Copper, or a Nickel-Copper alloy, the method improves the base coating toughness, anticorrosion, and antifouling properties for high load application in sea water and brackish water environments. Additionally, a Cobalt-free material lowers material costs and reduces the global demand of Cobalt. Providing a topcoat of a Silicon-doped DLC significantly reduces the topcoat brittleness of common DLC failures such as “egg shell” in high stress applications. Thus, high hardness, low friction applications may be tailored in high stress applications.

A ring base member of a disc seat ring is fixed to a valve disc using a bolt. The valve disc is formed of a first austenitic stainless steel containing 17.0% by mass to 21.0% by mass of Cr and 8.0% by mass to 13.0% by mass of Ni. The ring base member is formed of a second austenitic stainless steel containing 17.0% by mass to 20.0% by mass of Cr and 8.0% by mass to 15.0% by mass of Ni.

A water softener valve mechanism includes a body provided with a main inlet, a main outlet and a discharge. The body has a static valve plate provided with a first passage, a second passage, a third passage, a fourth passage, a blind fifth passage, a sixth passage and a seventh passage and a dynamic plate rotatable relative to the static plate and having an elongated blind hole defined in a side face of the dynamic plate and an aligning hole to selectively communicate with the first passage, the second passage, the third passage and the fourth passage and a driving device mounted inside the body to drive the dynamic valve plate to rotate.
