Device for a valve system, comprising: a housing with a seat for being coupled to a base and exchanging water streams when the housing is in a first coupling position, the seat comprising a first seat opening fluidly connecting to a first base opening when the housing is in the first coupling position; an adjuster which is contained inside the housing for adjusting the flow rate of one of the water streams; and a controller for controlling the adjuster. To avoid any complications in the event of an error while making the system more versatile, the seat comprises a breakable portion which can be broken off from the seat to enable it to be coupled in a second coupling position, the first seat opening subsequently fluidly connecting to a second base opening.

A valve housing (1) has first and third openings (1.1, 1.3), and first and second actuating elements (6.1, 6.2) that are movable along a longitudinal axis of the housing (1). A return element (5) is between the actuating elements (6.1, 6.2), and exerts a force to keep the actuating elements (6.1, 6.2) in a rest position to close or open the first and third openings (1.1. 1.3). First and second wires (4.1, 4.2) are formed from a shape memory alloy. The first wire (4.1) is on the first actuating element (6.1) and the second wire (4.2) is on the second actuating element (6.2). An electric current to the first or second wire (4.1, 4.2) contracts the respective wire (4.1, 4.2) and moves the corresponding actuating element (6.1, 6.2) into an activated position against the force exerted by the return element (5).

A refrigerator appliance includes a water system. The water system has a fluid circuit and valve assembly. The valve assembly is configured to control flow through the fluid circuit. The valve assembly has a valve, at least one actuator disposed on the valve, and a framework configured to secure the at least one actuator to the valve. The framework has first and second upright members, a crossmember, and an electrical connector. The first and second upright members secured to the valve on opposing sides of the at least one actuator. The crossmember is secured to opposing ends of the first and second upright members relative to the valve such that the valve, first upright member, second upright member, and crossmember form a closed loop around the at least one actuator. The electrical connector is electrically connected to the at least one actuator and is secured to the crossmember.

A valve including: a body having: a first aperture; a second aperture; a first channel in fluid communication with the first aperture; a second channel in fluid communication with at least part of the second aperture; and an outlet aperture; an adjusting portion associated with the body, the adjusting portion providing a stop; a piston in fluid communication with the first channel, the second channel and the outlet aperture; a thermostatic element configured to assist with moving the piston in response to engaging with the stop, the piston being configured to regulate fluid flow from the first channel and the second channel to the outlet; and a return spring configured to assist with biasing the thermostatic element, wherein part of the fluid flow entering the first channel flows along the piston and exits from a portion of the second aperture.

A valved manifold module is disclosed, constructed and arranged to be readily connected in a chain with similar modules to form a manifold assembly. The modular manifolds allows for expansion or modification of the manifold assembly to control a group of pneumatically or hydraulically driven pumps, valves or combinations thereof in a liquid flow control apparatus. The valved manifold module can be configured to accept a group of four substantially identical valve assemblies, and can be controlled by a local controller mounted to the manifold module, thus forming an independently programmable valved manifold module. The resulting modular system is expandable to allow for coordinated operations of a liquid flow control system, using substantially independent controller functions originating at the manifold assembly level.

A new and innovative high-pressure priming valve is provided for use in high-pressure fluid systems that require a high level of fluid purity. The priming valve includes at least three ports, some of which are angled. The priming valve also includes a needle that variably blocks and unblocks a pathway to one of the ports between normal operation and a priming operation, respectively. The priming valve includes a sealing insert positioned below a stack of washers that maintain the needle's alignment in response to high fluid pressures exerted on the needle. The sealing insert helps prevent fluid from contacting the stack of washers, which helps prevent biological growth within the valve. The angled ports help facilitate priming valve drainage to further help prevent biological growth. By helping prevent biological growth, the sealing insert helps prevent fluid contamination and enables the priming valve to be utilized for high-purity fluid applications.

A multi-fuel switching device, including a gas part, is provided. The gas part includes a switching valve. The switching valve includes a housing having an air inlet and an air outlet. An internal rotation of the housing is provided with a valve core located between the air inlet and the air outlet. The valve core is provided with a first airway and a second airway. Cross-sectional sizes of the first airway and the second airway are different. The first airway or the second airway is selected through rotating the valve core to connect the air inlet and the air outlet. The solution solves the issue that a fuel switching device in the prior art cannot adapt to three or more fuels, which causes an internal combustion engine to be unable to maintain the optimal working state.

A switching valve includes a valve body, a diaphragm, and a driving assembly. The valve body includes a valve cavity, a water inlet, a first water outlet, and a second water outlet in communication with the valve cavity. The diaphragm includes two unsealing parts connected with the driving assembly and respectively arranged opposite to the first water outlet and the second water outlet. Each unsealing part can control opening or closing of the first water outlet or the second water outlet. The driving assembly can individually drive each of the unsealing parts to switch between opening and closing such that at least one of the first water outlet and the second water outlet is in an open state.

A valve housing for a fluid valve having at least one fluid channel through which a fluid can flow is provided. The valve housing can have a receiving space for a valve closing body movable in the valve housing, the receiving space having an opening, via which the valve closing body is introduced into the receiving space of the valve housing, and at least one first valve seat being formed in the receiving space and projecting into the receiving space in such a way that at least one undercut is formed in the receiving space by the first valve seat, and the valve housing being an integral injection-molded part, the at least one valve seat being produced integrally with the valve housing by an injection molding process.

A valve apparatus that includes a valve assembly including a valve retainer body that houses a movable poppet that defines a valve member that is configured to contact a conically shaped valve seat of the valve retainer body; and a motor assembly including a rotatable shaft that is configured to actuate the valve assembly; wherein the rotatable shaft includes a thread formed at an end thereof, the thread being engaged with a sleeve that through rotation of the thread by the rotatable shaft will translate the sleeve towards and away from the movable poppet to transfer an axial force to the poppet that forces the valve member into engagement and disengagement with the valve seat to open and close the valve assembly.
