    摘要： Internal valve apparatus are described. An example internal valve includes a body having a valve seat disposed in a fluid flow passageway between an inlet and an outlet. A flow control member is operatively coupled to the body and movable between a first position to engage the valve seat to restrict fluid flow through the valve and a second position to move away from the valve seat to allow fluid flow through the valve. A removable actuator is coupled to the body and operatively coupled to the flow control member to cause the flow control member to move between the first and second positions. A portion of the removable actuator is cantilevered in the fluid flow passageway between the inlet and the outlet when the removable actuator is coupled to the body.

    摘要： Field removable bonnet assemblies for use with valves are described herein. An example field removable bonnet assembly for use with internal valves includes a body that is to be removably coupled to the internal valve. The body defines a bore that is to receive a valve packing. Additionally, the field removable bonnet assembly includes a shaft having a cam assembly that is to rotatably engage a stem of the internal valve. The shaft is rotatably coupled to the body and the shaft is at least partially positioned within the bore. Further, the field removable bonnet assembly includes a removable adjuster that is externally accessible to enable an adjustment of the removable adjuster relative to the body to change a force exerted by the valve packing on the shaft. The removable adjuster is field removable to replace or repair the valve packing.

    摘要： Fluid flow control members for use with valves are described herein. An example fluid flow control member for use with a valve includes a body having a first seating surface to control a flow of fluid through the valve. The body defines a second seating surface opposite the first seating surface to control a flow of fluid through the valve. Additionally, the body defines an aperture to receive a stem of the valve, and a bore surrounded by the first seating surface to receive at least one of a seal or a sliding member each of which have a first surface to be engaged by a second surface of a spring seat coupled to the stem to control a fluid flow through the valve.

    摘要： Methods and apparatus to indicate a position of a valve are described. An example position indicator apparatus includes a follower operatively coupled to a flow control member of a valve to sense a displacement of the flow control member. The example apparatus further includes a status indicator to provide an indication that corresponds to the displacement of the flow control member to determine one of a plurality of predetermined operational positions of the valve and a visual display to cooperate with the position indicator to indicate a position of the valve corresponding to one of the plurality of predetermined operational positions of the valve.

    摘要： Internal valve apparatus are described. An example internal valve includes a body having a valve seat disposed between an inlet and an outlet. A flow control member operatively coupled to the body moves between a first position in which the flow control member engages the valve seat to restrict the flow of fluid through the valve and a second position in which the flow control member is spaced from the valve seat to allow the flow of fluid through the valve. The example internal valve further includes a removable actuation member disposed within the body and responsive to a fluid pressure to cause the flow control member to move between the first and second positions.
