Valve assembly employable with a downhole tool |
| 摘要 |
A valve assembly employable with a downhole tool configured for conveyance in a wellbore extending into a subterranean formation and method of operating the same. The valve assembly includes an actuator and a sensing apparatus configured to provide a first signal based on an environment associated with the valve assembly and a second signal based on a characteristic of the valve assembly. The valve assembly also includes a controller configured to provide a third signal to the actuator to alter the characteristic in response to the first and second signals. |

1. An apparatus, comprising:
a downhole tool configured for conveyance in a wellbore extending into a subterranean formation having a valve assembly, comprising:
an actuator;a sensing apparatus configured to provide a first signal based on a parameter of an environment associated with the valve assembly and a second signal based on a rotational position of a valve; anda downhole controller in the valve assembly configured to provide a third signal to the actuator to alter the position in response to the first and second signals. |
