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 seat to control a fluid flow through the valve. The body defines a seating surface, an aperture to receive a stem of the valve and a plurality of substantially flat surfaces to enable gripping an exterior surface of the body.

Fluid flow control members for use with valves

Fluid flow control members for use with valves are described. An example poppet apparatus for use with an internal valve includes first and second opposing seating surfaces to control fluid flow through the internal valve. Additionally, the example poppet apparatus includes an aperture to receive a stem of the internal valve. Further, the example poppet apparatus includes a flow diverter to divert fluid flow through the poppet apparatus to substantially prevent the fluid flow from compressing a spring to be at least partially positioned in the poppet apparatus.

Field removable bonnet assemblies for use with valves are disclosed. An example internal valve includes an internal valve body and a field removable bonnet assembly. The field removable bonnet assembly includes a body that is to be removably coupled to the internal valve body and a shaft to be at least partially positioned within the body. The field removable bonnet assembly also includes an adjuster including a first adjuster portion and a second adjuster portion. The body defines a bore having a first diameter portion and a second diameter portion larger than the first diameter portion. The first diameter portion is to receive a valve packing. The second diameter portion to be threadably engaged by the second adjuster portion. The adjuster is externally accessible to adjust the first adjuster portion within the first diameter portion to change a force exerted by the valve packing on the shaft.

Redundant metal-to-metal seals for use with internal valves are described. A plug having redundant sealing functionality for use with a poppet of an internal valve includes a tapered surface to sealingly engage a seat of the poppet. Additionally, the plug includes a seal adjacent the tapered surface and disposed in a groove defined by the plug to sealingly engage the seat.

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.

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.
