A two-piece valve shell (body and bolted-on top bonnet) structure reduces possible leakage paths while also providing a top-side ball/stem installation/removal path (when the bonnet piece is not present) to facilitate initial valve assembly as well as subsequent inspection/removal of the ball/stem and other valve internals for conducting valve maintenance without requiring the valve body to be removed from its process connections. Internal wetted valve surfaces are coated with tantalum to provide a tantalum ball valve suitable for use as a sulfuric acid feed valve in severe high-temperature high-pressure industrial processes such as HPAL processes. Sealing cavities created by spaced-apart body-to-bonnet and/or stem-to-bonnet sealing structures can be inertly pressurized to hermetically isolate the sealing structures from ingress/leakage of corrosive process materials.

A valve including a valve body; an adjusting assembly having an actuating portion and a regulating part; a flood prevention device at least partly located in the valve body, with the flood prevention device having a regulating portion; and a relief aperture defined through a wall of the regulating part to assist in reducing pressure on the regulating portion when the regulating portion moves to a closed position.

A multi-way refrigerant valve includes an outer housing having an open surface, and in which a first inlet, a second inlet, and a third inlet, and a first outlet, a second outlet, a third outlet, a fourth outlet, a fifth outlet, and a sixth outlet are formed, an inner housing rotatable inside the outer housing to connect the inlets and the outlets, and including at least one connection flow path formed therein, and a cover member mounted to the open surface of the outer housing. As the inner housing is rotated at a predetermined interval by the driving unit, the first inlet is connected to one or both of the first outlet or the second outlet, the second inlet is connected to one of the third outlet or the fourth outlet, and the third inlet is connected to one or both of the fifth outlet and or the sixth outlet.

The present invention relates to a multiway valve for controlling at least one flow of at least one fluid, in particular within a motor vehicle, including at least one housing and one valve member disposed at least in areas within at least one valve space which is configured at least in areas within the housing, and by way of changing a rotary position of the valve member within the valve space about a first rotary axis, at least the amount of an inflow of the fluid from at least one first fluid connector into the valve space and/or at least the amount of outflow of the fluid out of the valve space is adjustable by at least one second fluid connector, and the multiway valve includes at least one insert which is disposed at least in areas between the valve member and the housing and is connected in a rotationally fixed manner to the housing.

A component for a ball valve that is configured to reduce noise. The component or “shoe” can install into the valve body, for example, on a downstream side of a throttling ball. In one implementation, the embodiments comprise an annular ring with an inner surface and an outer surface. The inner surface is cupped to receive a portion of the throttling ball. The outer surface may have a stepped profile with portions of the annular ring that have concentrically-decreasing diameter. This stepped profile sits in a corresponding recess in the valve body. Welds can be used to secure the shoe in place in lieu of fasteners, like bolts or screws.

A valve assembly including a valve having an opening and closing mechanism for controlling the flow of a fluid through the valve controlled by an actuator and an actuator mounting bracket secured to the valve. The actuator mounting bracket includes upper and lower clamps securing the valve actuator to the valve regardless of the valve position.

Gas circuit (1) for a kitchen appliance (2) comprising a gas rail (3) with a gas inlet (4) for connecting said gas rail (3) to a gas source (5) and with at least one gas outlet (6), said gas circuit (1) further comprising a gas tube (7) for providing gas from said gas outlet (6) to a gas hob (8), and said gas circuit (1) further comprising a gas valve assembly (9) connecting said gas tube (7) to said gas outlet (6) of said gas rail (3) in a flow conducting manner, said gas valve assembly (9) comprising a gas valve (10) with a valve body (11) and fixation means (12) fixing said valve body (11) to said gas rail (3) such that said gas valve (10) is supported by said gas rail (3), characterized in that said fixation means (12) comprise a first spring member (13a) looping around said gas rail (3) and/or said valve body (11), thereby resiliently bracing said gas valve (10) and said gas rail (3).

An actuator mounting kit and method for mounting an automatic valve actuator to a manually operated valve. The mounting kit includes a mounting bracket and a stem driver. The mounting bracket is connectable to the valve and has a bottom portion with a stem aperture through which a valve stem is extendable and a tongue matingly engageable with a slot of the valve body. The mounting bracket has an upper portion with a driver aperture aligned with the stem aperture. The stem driver has a first end matingly engageable with the valve stem and a second end extendable through the driver aperture in a way that the actuator is matingly enageable with the second end of the stem driver when the actuator is connected to the upper portion of the mounting bracket.

A stopcock for a channel that guides a flux medium in a medical endoscope, the stopcock having a housing accommodating a plug rotatable about an axis in a conical seat penetrated by the channel, wherein the housing has a bearing collar adjacent to the conical seat in the direction of the axis, in which bearing collar a handle body is mounted to be rotatable about the axis, the handle body supporting a handle outside the housing and rotationally coupled to the plug displaceable in direction of the axis and resiliently supported relative thereto, wherein the handle body has a radially elastic detent device engaging a circumferential inner groove of the bearing collar to be locking in direction of the axis, wherein the plug is arranged and configured bring the detent device out of engagement with the bearing collar upon displacement in direction of the axis into an unlocked position.
