Cleanout conduit valve installations may include at least one cleanout housing having a cleanout housing interior and configured for placement in the cleanout conduit hole with the at least one cleanout conduit extending into the cleanout housing interior. A cleanout housing opening may overlie the cleanout housing interior. An openable cleanout housing door may be disposed in the cleanout housing opening. At least one cleanout conduit valve assembly may be configured to be disposed in fluid communication with the at least one cleanout conduit in the cleanout housing interior of the at least one cleanout housing. The at least one cleanout conduit valve assembly may include a valve housing configured for mounting on the at least one cleanout conduit. A valve mount may be carried by the valve housing. A valve may include a valve arm pivotally carried by the valve mount. A valve stop may extend from the valve arm. A valve body may be carried by the valve arm. The valve body may have a sealing surface. The valve may be positional between a closed valve position configured to seal the valve housing and a full open valve position configured to unseal the valve housing. The valve stop may engage the valve body in the full open valve position.

Disclosed is a valve, comprising a valve body, an inner valve seat and a valve core. The valve core is mounted in the valve body. The inner valve seat is mounted in the valve body. The inner valve seat has a annular body and a seal structure extending inwards from an inner peripheral surface of the annular body, wherein the seal structure is arranged in such a manner that the seal structure seals a gap formed among the valve body, the inner valve seat and the valve core when the valve is in a closed state. After the valve is used for discharging liquid, the amount of liquid residue inside the valve can be greatly reduced.

The invention relates to a valve assembly (100) for a multi-scroll turbine (10) for controlling an overflow of exhaust gases between a first spiral (36) and a second spiral (38) and for controlling a bypass opening (50). The valve assembly 100 comprises a lever (110) and a valve closing element (120) which is operatively connected to the lever (110). Furthermore, the valve assembly (100) comprises a spring element (130) which is designed to pre-bias the valve closing element (120) the against lever (110).

A hinged valve is provided. The hinged valve includes a valve body, a valve stem, a valve disc, an actuator and a sliding member. The valve body is a housing, which is provided with a valve stem hole for partially accommodating the valve stem. The valve body has a passage with an inlet and an outlet. The valve disc is connected to the valve body through a hinge, so that the valve disc is able to rotate around the rotation axis of the hinge.

A mass spectrometer is disclosed comprising a rotatable isolation valve (1) having a curved, spherical, cylindrical or concave portion. At least a portion of an ion guide (2) is positioned so as to extend within a swept volume of the isolation valve (1) enabling the ion guide (2) to be positioned close to a second downstream ion guide (3) and for ions to be transmitted from the first (2) ion guide to the second ion guide (3) with high ion transmission efficiency.

Cleanout conduit valve installations may include at least one cleanout housing having a cleanout housing interior and configured for placement in the cleanout conduit hole with the at least one cleanout conduit extending into the cleanout housing interior. A cleanout housing opening may overlie the cleanout housing interior. An openable cleanout housing door may be disposed in the cleanout housing opening. At least one cleanout conduit valve assembly may be configured to be disposed in fluid communication with the at least one cleanout conduit in the cleanout housing interior of the at least one cleanout housing. The at least one cleanout conduit valve assembly may include a valve housing configured for mounting on the at least one cleanout conduit. A valve mount may be carried by the valve housing. A valve may include a valve arm pivotally carried by the valve mount. A valve stop may extend from the valve arm. A valve body may be carried by the valve arm. The valve body may have a sealing surface. The valve may be positional between a closed valve position configured to seal the valve housing and a full open valve position configured to unseal the valve housing. The valve stop may engage the valve body in the full open valve position.

The invention relates to a valve assembly (10) for a charging device, in particular for a wastegate of an exhaust gas turbocharger, comprising a spindle (100), a lever arm (110) coupled to the spindle (100), and a valve unit (200). The lever arm (110) has a connecting element (112), designed as at least partially spherical, and the valve unit (200) has an accommodation region (212) with at least one first conical accommodation surface (214) in which the connecting element (112) is arranged.

Pivot valves have a valve seat and a valve closure mounted for pivoting movement through a closure chamber in a passage. The pivot valves may be selectively set in a check mode and an open mode. Flapper valves have a hydrofoil extending from a flapper. Valve assemblies comprise the pivot valves and flapper valves and have an open condition, a check condition, and a shut-off condition.

A valve for use in an engine exhaust conduit. The valve includes a base portion and a body portion extending from the base portion. The base portion is configured for pivotably mounting the valve within the engine exhaust conduit. The base portion defines a valve pivot axis. The valve is pivotable about the valve pivot axis during use. The body portion has an upstream side and a downstream side opposite the upstream side. The upstream side is exposed, during use, to fluid flow in the engine exhaust conduit. The body portion has a generally pointed shape defining a rounded tip at a location of the body portion furthest from the base portion in a length direction of the valve. The length direction of the valve is generally perpendicular to the valve pivot axis.
