Patent ID: 7415376

Claim:
A valve exercising system for rotating a valve between open and closed conditions, the system comprising: a fluid pump for moving fluid through the system through a fluid path; a fluid motor for being operated by fluid moving through the fluid path; a connector configured to connect the fluid motor to a valve for rotating the valve between an open condition and a closed condition; a torque sensor in communication with the motor, the torque sensor being configured to sense torque generated by the fluid motor for applying to the connector; a rotation speed sensor in communication with the motor, the rotation speed sensor being configured to sense the speed of rotation of the fluid motor; a torque controller in communication with the fluid path, the torque controller being manually adjustable by a user to control an amount of torque generated by the fluid motor; a rotation speed controller in communication with the fluid path, the rotation speed controller being manually adjustable by the user to control the speed of rotation of the motor; and an alarm device in communication with the torque sensor, the alarm device being configured to generate an alarm when the torque sensor senses the torque of the fluid motor reaches a threshold level.
