A valve block includes a fluid-transfer plate with multiple inlet bores connecting to a common inlet channel, and multiple outlet bores connecting to a common outlet channel. The inlet bores and the outlet bores are arranged in a curved shape. The valve block also includes a pressure plate and diaphragm aligned and connected to the fluid-transfer plate in a way that allows pressurized material in the pressure plate to control the state of the channels formed by the inlet and outlet bores.

A valve device includes a body, a solenoid valve, and a manual valve mounted to the body. The manual valve being configured to open and close the gas flow channel via a manual operation. The gas flow channel includes a first flow channel including the valve-side opening portion, and a second flow channel including the tank-side opening portion, and includes an intersection portion in which a first center axis that is a center axis of the first flow channel and a second center axis that is a center axis of the second flow channel intersect with each other. A center axis of the solenoid valve coincides with an extension line of the first center axis and a center axis of the manual valve coincides with an extension line of the second center axis.

An attachment structure includes expansion valves used in a vehicle, and a housing to which the expansion valves are attached. The housing includes a flow path through which heat medium circulating in a heat pump cycle of an air conditioner of the vehicle flows, and the flow path is opened and closed by the expansion valves.

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.

In some implementations, an apparatus comprises a pipe, a stud that is forge-welded to the pipe, creating a forge-welded stud, a bracket that is operably coupled to the forge-welded stud, and a ladder support operably coupled to the bracket.

An integrated multi-port solenoid valve, comprising: at least two sub-solenoid valves (20), each sub-solenoid valve (20) comprising at least two connection ports; and at least one first joint (30), each first joint (30) comprising at least two connection joints, wherein at least one first connection port in the at least two connection ports is used for connection to other sub-solenoid valves (20), each first joint (30) is used for connecting any two sub-solenoid valves (20), and each connector joint is connected to the first connection port. The present integrated multi-port solenoid valve integrates multiple sub-solenoid valves, and any connection ports of each sub-solenoid valve is communicated with each other to meet control requirements of a variety of working conditions. The integrated multi-port solenoid valve has lightweight design, few components, a light weight, and low cost of use. Also provided are a vehicle thermal management system and a vehicle.

Passage forming blocks of a first pilot valve and a second pilot valve each include a supply passage, which opens in a first surface and a second surface and is connected to a valve chamber, a first output passage, which opens in the first surface and are connected to the valve chamber, and a second output passage, which opens in the first surface. Further, the passage forming blocks each include an output passage connecting recess. The output passage connecting recess is provided in a section of the second surface that overlaps with an opening region of the first output passage, which opens in the first surface, and is connected to the second output passage. The first output passage of the first pilot valve is connected to the second output passage of the second pilot valve via the output passage connecting recess of the second pilot valve.

A valve block may be assembled, in a controlled environment, a valve block to be modular and purpose built for a specific application. The specific application may be an operation to be performed at a well site. The modular purpose built valve block may be function tested, in the controlled environment. Additionally, the modular purpose built valve block may be pre-packaged, in the controlled environment, to have a digital system to operate and automate the modular purpose built valve block. Further, the modular pre-packaged purpose built valve block may be deployed to the well site, and the modular pre-packaged purpose built valve block may be fluidly coupled to a wellhead. The modular pre-packaged purpose built valve block may be operated to perform the operation at the well site.

A housing assembly for a manifold includes a first housing with an inlet and a plurality of outlets, a second housing, and a valve retainer engaged with the first and second housings. The valve retainer includes a retention plate defined between first and second surfaces, a plurality of slot walls extending from the first surface, and a protruding edge that extends from a flanged lip and surrounds the plurality of slot walls. The retention plate defines a plurality of slots corresponding to the plurality of slot walls. The first housing may define a groove that receives the protruding edge, and the second housing may include a rim that engages the flanged lip of the valve retainer. Valve housings including first and second mating structures separated by wall segments may be positioned in outlets of the first housing and corresponding slots of the valve retainer.
