Valves having removable internal actuation mechanisms |
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.
