A pipe cleaning assembly has a connection fixture having a body defining a cavity. A first aperture, opposing first auxiliary aperture coaxially aligned with the first aperture, second aperture, and opposing second auxiliary aperture coaxially aligned with the second aperture are in fluid communication with the cavity. A first connection flange extends from and surrounds the first aperture, a second connection flange extends from and surrounds the second aperture, a third connection flange extends from and surrounds the first auxiliary aperture, and a fourth connection flange extends from and surrounds the second auxiliary aperture. A bonnet is inserted through the second auxiliary aperture and is positioned within the cavity of the body and includes a generally cylindrical wall and a plurality of openings formed through the cylindrical wall to direct fluid flowing through the connection fixture.

Example seal glands for butterfly valves are disclosed herein. An example butterfly valve disclosed herein includes a valve body and a valve retainer mounted to the valve body, where the valve body and the valve retainer define a circumferential cavity. The example circumferential cavity includes a first surface substantially perpendicular to a longitudinal axis of a flow path of process fluid through the butterfly valve, a second surface substantially perpendicular to the longitudinal axis, where the second surface offset from the first surface, and a third surface extending between the first surface and the second surface. In the example butterfly valve, the first surface, the second surface, and the third surface enable a seal to translate within the cavity in a direction substantially parallel to the first surface.

A thrust bearing for use with a rotary valve is provided. The thrust bearing includes a journal portion and a thrust portion. The journal portion is sized to be disposed between a valve body of the rotary valve and a drive shaft of the rotary valve. The thrust portion is sized to be disposed between the valve body and a control member disposed within the valve body and movable relative to a valve seat disposed within the valve body via a drive shaft to control fluid flow through the valve body. The thrust portion includes a flat surface adapted to engage a corresponding flat surface of the valve body when the bearing is subject to a combined thrust and torsional load via the drive shaft, such that the bearing can accommodate the combined thrust and torsional load.

Bearing for rotary control valve

Actuator stem and rod end bearings having locking mechanisms are described. An example apparatus for use with a control valve actuator includes a rod end bearing having a bearing retainer and a shaft portion extending from the bearing retainer, where the shaft portion defines a first face. An actuator stem has a first end to be operatively coupled to a diaphragm plate of the control valve actuator and a second end to be coupled to the rod end bearing, where the second end defines a second face. The first face engages the second face to provide a lock that prevents rotation of the actuator stem relative to the rod end bearing when the actuator stem is rotated in a first direction.

Apparatus to bias valve closure members are described. An example valve includes a valve body having an opening defining a passageway. The opening has an axis that is substantially coaxially aligned with a flow path axis defined by the passageway. A first shaft supports a closure member within the passageway of the valve body and relative to the opening and an end cap removably coupled to the valve body retains the shaft within a bore of the valve body. A spring is disposed between the first seating surface and a second seating surface opposite the first seating surface to provide a force to oppose the weight of the closure member and facilitate alignment of the closure member relative to the opening of the passageway.

Apparatus to bias valve closure members

Actuator stem and rod end bearings having locking mechanisms are described. An example apparatus for use with a control valve actuator includes a rod end bearing having a bearing retainer and a shaft portion extending from the bearing retainer. The apparatus also includes an actuator stem having a first end to be operatively coupled to a diaphragm plate of the control valve actuator and a second end to be coupled to the rod end bearing. A locking mechanism coupled to the actuator stem or the rod end bearing prevents the actuator stem and the rod end bearing from decoupling when the actuator stem is coupled or de-coupled to the diaphragm plate.

Actuator stem guide apparatus for use with fluid valve actuators are described. An example actuator stem guide apparatus includes a base having an opening to allow an actuator stem of the fluid valve actuator to tilt or lean within the base to enable a lever of the fluid valve actuator to rotate and a guide receiving area adjacent the opening of the base. A guide is coupled to the guide receiving area and the guide has a bearing surface to slidably engage the actuator stem to limit lateral movement of a diaphragm assembly relative to a longitudinal axis of the opening to prevent the diaphragm assembly from engaging an inner surface of an actuator housing as the actuator stem moves between a first position and a second position.

A biasing apparatus includes a first spring seat that has a first seating surface and a first protruding member extending a predetermined distance from the first seating surface and a second spring seat that has a second seating surface and a second protruding member extending a predetermined distance from the second seating surface. The first and second protruding members engage to slidably couple the first and the second spring seats.
