Abstract
A trim system for a fluid control valve that includes a first stem driver coupled to a first actuator of the valve, a cage coupled to the first stem driver, a first handle coupled to the cage, a second stem driver coupled to a second actuator of the valve, and a second handle coupled to the second stem driver. The first stem driver and the cage are configured to compensate for axial and angular misalignment between the first handle and the first actuator, and the second stem driver and the second handle are configured to compensate for axial and angular misalignment between the second handle and the second actuator. Rotation of the first handle is configured to rotate the first actuator through the first stem driver and the cage, and rotation of the second handle is configured to rotate the second actuator through the second stem driver.
