Abstract
Actuator levers, collets and collet tools for use in process control devices are disclosed. An example apparatus includes a tool for installing or removing a collet from an actuator lever. The example tool comprises a tool body and at least one of a plurality of inner-diameter threads, a plurality of outer-diameter threads, or a plate to removably couple the tool to at least one of an actuator lever or a collet. The tool is configured to apply a force to at least one of the actuator lever, the collet, a valve shaft, or an intervening structure to install the collet in or remove the collet from the actuator lever.
Claims22
A process control apparatus comprising:
- an actuator lever;
- a collet;
- and
- a tool for installing or removing the collet from the actuator lever, the tool comprising:
- a tool body;
- and
- at least one of a plurality of inner-diameter threads, a plurality of outer-diameter threads, or a plate to removably couple the tool to at least one of the actuator lever or the collet, wherein the tool is to apply a force to at least one of the actuator lever, the collet, a valve shaft, or an intervening structure to install the collet in or remove the collet from the actuator lever.
A process control apparatus comprising:
- an actuator lever;
- a collet;
- and
- means for installing the collet in or removing the collet from the actuator lever, wherein the means for installing or removing comprises:
- means for removably coupling a collet tool to at least one of the actuator lever or the collet;
- and
- means for applying a force through the collet tool to at least one of the actuator lever, the collet, a valve shaft or an intervening structure to install the collet in or remove the collet from the actuator lever.
