An angle ball valve includes a housing, valve chamber, and first and second fluid ports. A hollow ball is disposed within the valve chamber and in abutment to sealing elements, and includes a first surface opening and second surface opening and is rotatable within the valve chamber about an axis of ball rotation between open and closed ball valve positions. A first sensor orifice is formed within the valve housing coaxial with the axis of ball rotation and receives a sensor, which extends into a second sensor orifice of the ball. A valve stem is operatively connected to the ball and extends along the axis of ball rotation opposite the first sensor orifice. The valve stem rotates the ball into and out of open and closed ball valve positions.

Gas meters including a first portion and a second portion are provided. The first portion is separate and distinct from the second portion and a physical barrier is positioned between the first portion and the second portion. The first portion includes at least a motor associated with a shut-off valve for the gas meter and the second portion includes at least an area for a gas stream to flow through. Related gas regulating devices are also provided herein.

The embodiments disclosed herein relate to an apparatus for monitoring a valve having: a body of the valve containing a control element; a neck extending from the body of the valve and connected to a mounting support, wherein the neck partially houses a valve stem connected to the control element and further wherein the valve stem extends through the mounting support; a gland ring mounted around the valve stem, wherein the gland ring is partially within the mounting support; a gland retainer mounted above the gland ring within the mounting support; one or more fasteners connecting the gland retainer to the body of the valve; and one or more load cells mounted around the fasteners and located above the gland retainer, wherein each load cell is configured to sense a clamping force between a top surface and a bottom surface of the load cell.

Valve body insert apparatus and related methods are described. An example method includes inserting a first sleeve in a drive shaft bore of a valve body. The first sleeve is to line a first inner surface of the drive shaft bore to protect the first inner surface of the drive shaft bore from corrosion or erosion, and the first sleeve defining a first opening to receive a drive shaft. The method includes applying cladding to wetted surfaces of the valve body defining a fluid flow passageway and to at least a portion adjacent a first end of the first sleeve positioned in the fluid flow passageway, where cladding material is not applied to portions of the first inner surface of the drive shaft bore covered by the first sleeve.

A throttle body or actuator for an engine, comprising a main body which defines at least one supply duct having a through lumen for a gas mixture, a choke valve placed inside said supply duct so as to modify said through lumen. The choke valve is provided with an occluding body connected to a control shaft, at least partially housed in a seat in the main body. The control shaft, inside the seat and on the side of the occluding body, is provided with a first gasket adapted to prevent the penetration of dirt and gas from the supply duct. Downstream of the first gasket, on the side of the control shaft, at least one vent is provided, adapted to allow the expulsion, outside the seat, of any gas which has leaked through the first gasket.

The invention relates to a shaft passage and a valve having such a shaft passage, as well as a method for producing a shaft passage, in which the shaft (21) has at least one drive portion (24) to which a drive for controlling the shaft (21) can be connected and has a connecting portion (25) opposite the drive portion (24), to which an actuating member (64) can be connected, and an inner shaft portion (26) in the through-bore (22) extending at least partially in the through bore (22), and having an inner shaft seal (36) to which an operating pressure of a medium to be controlled by the actuating member (64) is applied, and having a fluid shaft seal (34) which extends in the direction of the drive portion (24), and which is arranged between the inner shaft seal (34) and the outer shaft seal (42), wherein the fluid shaft seal (34) is formed between the through bore (22) and the inner shaft portion (26) of the shaft (21) and is pressure-relieved against an operating pressure of the medium to be controlled.

A stuffing box assembly for a valve includes a stuffing box and a packing module. The packing module carries one or more seals to engage with the stuffing box and a valve stem extending through the stuffing box. The packing module is able to be installed into, and removed from, the stuffing box as a single assembly. A valve stem can be formed with an integral ball on one end for engaging with a valve seat. The seals of the packing module create a fluid-tight seal against the valve stem and the stuffing box to inhibit fluid leakage through the stuffing box.

A connection socket for a tubular connection that includes: a socket cup having a metal alloy composition and a sealing portion, the sealing portion comprises a primary and a secondary sealing recess; a primary seal positioned within the primary sealing recess, the primary seal comprising an elastomeric material having a service temperature, and a secondary seal positioned within the secondary sealing recess, the secondary seal comprising a metal composition. Further, the secondary seal has a melting temperature at or above the service temperature of the primary seal.

A valve includes a housing and a rotary body arranged notably therein with a through opening for a fluid, wherein a flow path is shut off or is at least partially opened in accordance with the rotational angle position of the rotary body about an axis of rotation, wherein the rotary body is connected to a spindle by which the rotary body is rotatable, wherein the housing is provided with a covering, and wherein the spindle reaches through the covering. The spindle is dynamically sealed by a sealing device which follows movements of the spindle relative to the housing and/or to the covering.
