摘要
A valve control system for a wellbore includes a fiber composite actuator functionally coupled to a valve operating member and means for controllably charging an interior of the actuator with fluid under pressure. A valve for a wellbore includes a valve stem and a valve seat associated with a valve body. The valve stem and valve seat are configured to enable fluid flow from an inlet port in the valve body to an outlet port in the valve body when the stem is moved from the seat. An axial contraction fiber composite actuator is functionally coupled to the valve stem. The valve includes means for controllably charging an interior of the actuator with fluid under pressure.
