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.

摘要： Methods and apparatus to indicate a position of a valve are described. An example position indicator apparatus includes a status indicator to provide an indication that corresponds to a displacement of a poppet relative to a seat ring of the fluid valve to determine one of a plurality of predetermined operational positions of the fluid valve. A follower is coupled to the poppet to follow movement of the poppet between the plurality of predetermined operational positions of the fluid valve. A coupler operatively couples the status indicator and the follower.
