A seat leak measurement system for a ball valve is described. The system includes: a ball valve with a cavity drain line, the ball valve including a cavity pressure sensor; a valve seat leak measurement apparatus including: a cable with a connector, the connector having an external grounding cable; an apparatus electronic control system in communication with the valve sensor retrieval fitting and with valves of the valve seat; an fluid inlet line with a quick pipe coupler, the fluid inlet line having an apparatus drain valve and an isolation valve; a pressure indicator transmitter connected to the fluid inlet line, the pressure indicator transmitter in electronic communication with the apparatus electronic control system; a temperature indicator transmitter connected to the fluid inlet line, the temperature indicator transmitter in electronic communication with the apparatus electronic control system; and a flow elements manifold receiving fluid from the fluid inlet line.

This disclosure relates to a valve comprising a housing, an actuating shaft and a plurality of groups of valve body elements. The plurality of groups of valve body elements are disposed in the housing and capable of rotating in the housing. The actuating shaft is configured to selectively actuate at least one group of valve body elements in the plurality of groups of valve body elements to rotate. The valve is provided with a plurality of fluid passages therein, and the actuated at least one group of valve body elements can connect or disconnect at least one of the plurality of fluid passages. The valve provided by the present disclosure can control and switch more fluid passages when an output power of an actuating device is limited.

An actuator housing for a valve apparatus for a coolant circuit of a motor vehicle includes an actuator housing part for receiving at least one actuator component. The actuator housing also includes a valve housing part for at least partially limiting and hydraulically sealing a region of a valve device to be hydraulically sealed.

A control valve assembly includes a valve body defining an inlet, an outlet and a fluid flow pathway therebetween. A ball valve is positioned within the fluid flow pathway and includes a rotatable ball having an inlet opening, an outlet opening and a flow pathway therebetween, an upstream seat ring positioned at an inlet side of the ball, and a downstream seat ring positioned at a downstream side of the ball, the seat rings being configured to substantially seal off fluid flow between upstream and downstream sides of the ball except through the ball fluid flow pathway. At least one of the upstream and downstream seat rings is a dynamic sealing seat ring. A retainer ring is positioned between the dynamic sealing seat ring and a portion of the rotatable ball to substantially prevent deformation of a portion of the dynamic sealing seat ring in a direction toward the ball.

A press-fitting component (1) including at least one main body (2) having at least one inlet (4), at least one outlet (5) and at least one channel (3) connecting the inlet (4) with the outlet (5), as well as at least one press-fitting (90) defined in correspondence of at least one of the outlet (5) and the inlet (4) of the main body (2). The press fitting further comprises a predetermined number of projections (9) emerging internally from the main body (2) and made in one piece with the main body (2). A process of assembling the component (1) with a pipe and a process of manufacturing the component (1).

A fire extinguishing system valve (1), in particular wet alarm valve, dry alarm valve or spray water valve, having a housing (3) which has a fluid inlet chamber (9), a fluid outlet chamber (11) and a closing body (13) which can move back and forth between a blocking state and a release state, wherein the fluid inlet chamber (9) and the fluid outlet chamber (11) communicate directly with one another in a fluid-conducting manner in the release state, and the closing body (13) prevents the direct communication between the fluid inlet chamber (9) and the fluid outlet chamber (11) in the blocking state. The housing (3) has a dedicated discharge duct (30) which has at least one inlet (30a, b) connected to the fluid outlet chamber (11) and an outlet (30c) leading out of the housing (3) of the fire extinguishing system valve (1), and which is integrated into the housing (3).

A fluid valve, in particular for a motor vehicle and/or a temperature control system, having a housing and a valve body disposed in the housing so as to be rotatable about a rotation axis. The housing has a first port and a third port disposed on opposite side of a normal plane in relation to the rotation axis and a second port which is radially spaced apart from the rotation axis and in the direction of the rotation axis is disposed between the first and the third port. The valve body in at least one rotary position connects at least two ports of the housing to one another, and in at least one other rotary position does not connect the two ports to one another.

An apparatus for handling fluid within an at least partially electrically powered vehicle, including: a valve device with a valve housing, the valve housing includes at least eight radially arranged port openings for fluid to flow in or out, a valve body, which is arranged inside the valve housing and is rotatable about an axis of rotation R, and the valve body includes at least four connecting channels for fluidly connecting two port openings, respectively.

A valve having a hollow body which extends along a main axis (X), in which at least one secondary body is arranged at one end of the hollow body substantially coaxial to the main axis (X) and has an inner end portion with a collar protruding towards the inner surface of the hollow body is disclosed. The hollow body has at least one annular groove in which a ring is arranged at least partially to prevent the movement of the secondary body towards the end of the hollow body, in which the ring is divided into at least two arcs configured to be inserted individually inside the groove of the hollow body to form the ring.

An operation valve includes a valve that controls the flow of a fluid, a cylindrical operator that operates opening and closing of the valve by rotating the operator in a peripheral direction, and has a first step parallel to a central axis of the operator, a storage that stores the valve, includes a flow channel of the fluid therein, and has a second step corresponding to the first step on an outer periphery of the storage in a first state in which the valve is closed, and an elastic body that urges the operator toward the storage.
